Therefore, do not attempt the optimization // ** if: // ** // ** (6a) The inner query uses multiple incompatible window partitions. // ** // ** (6b) The inner query is a compound and uses window-functions. // ** // ** (6c) The WHERE clause does not consist entirely of constants and // ** copies of expressions found in the PARTITION BY clause of // ** all window-functions used by the sub-query. It is safe to // ** filter out entire partitions, as this does not change the // ** window over which any window-function is calculated. // ** // ** (7) The inner query is a Common Table Expression (CTE) that should // ** be materialized. (This restriction is implemented in the calling // ** routine.) // ** // ** (8) If the subquery is a compound that uses UNION, INTERSECT, // ** or EXCEPT, then all of the result set columns for all arms of // ** the compound must use the BINARY collating sequence. // ** // ** (9) All three of the following are true: // ** // ** (9a) The WHERE clause expression originates in the ON or USING clause // ** of a join (either an INNER or an OUTER join), and // ** // ** (9b) The subquery is to the right of the ON/USING clause // ** // ** (9c) There is a RIGHT JOIN (or FULL JOIN) in between the ON/USING // ** clause and the subquery. // ** // ** Without this restriction, the WHERE-clause push-down optimization // ** might move the ON/USING filter expression from the left side of a // ** RIGHT JOIN over to the right side, which leads to incorrect answers. // ** See also restriction (6) in sqlite3ExprIsSingleTableConstraint(). // ** // ** (10) The inner query is not the right-hand table of a RIGHT JOIN. // ** // ** (11) The subquery is not a VALUES clause // ** // ** (12) The WHERE clause is not "rowid ISNULL" or the equivalent.

A single doclist may span multiple pages. Care is ** taken to ensure it is possible to iterate in either direction through ** the entries in a doclist, or to seek to a specific entry within a ** doclist, without loading it into memory. ** ** * large doclists that span many pages have associated "doclist index" ** records that contain a copy of the first rowid on each page spanned by ** the doclist. This is used to speed up seek operations, and merges of ** large doclists with very small doclists. ** ** * extra fields in the "structure record" record the state of ongoing ** incremental merge operations. ** */ /* ** There are two versions of the format used for the structure record: ** ** 1. the legacy format, that may be read by all fts5 versions, and ** ** 2. the V2 format, which is used by contentless_delete=1 databases. ** ** Both begin with a 4-byte "configuration cookie" value. Then, a legacy ** format structure record contains a varint - the number of levels in ** the structure. Whereas a V2 structure record contains the constant ** 4 bytes [0xff 0x00 0x00 0x01]. This is unambiguous as the value of a ** varint has to be at least 16256 to begin with "0xFF". And the default ** maximum number of levels is 64. ** ** See below for more on structure record formats. */ /* ** Details: ** ** The %_data table managed by this module, ** ** CREATE TABLE %_data(id INTEGER PRIMARY KEY, block BLOB); ** ** , contains the following 6 types of records. See the comments surrounding ** the FTS5_*_ROWID macros below for a description of how %_data rowids are ** assigned to each fo them. ** ** 1. Structure Records: ** ** The set of segments that make up an index - the index structure - are ** recorded in a single record within the %_data table. The record consists ** of a single 32-bit configuration cookie value followed by a list of ** SQLite varints. ** ** If the structure record is a V2 record, the configuration cookie is ** followed by the following 4 bytes: [0xFF 0x00 0x00 0x01]. ** ** Next, the record continues with three varints: ** ** + number of levels, ** + total number of segments on all levels, ** + value of write counter. ** ** Then, for each level from 0 to nMax: ** ** + number of input segments in ongoing merge. ** + total number of segments in level. ** + for each segment from oldest to newest: ** + segment id (always > 0) ** + first leaf page number (often 1, always greater than 0) ** + final leaf page number ** ** Then, for V2 structures only: ** ** + lower origin counter value, ** + upper origin counter value, ** + the number of tombstone hash pages. ** ** 2. The Averages Record: ** ** A single record within the %_data table. The data is a list of varints. ** The first value is the number of rows in the index. Then, for each column ** from left to right, the total number of tokens in the column for all ** rows of the table. ** ** 3. Segment leaves: ** ** TERM/DOCLIST FORMAT: ** ** Most of each segment leaf is taken up by term/doclist data. The ** general format of term/doclist, starting with the first term ** on the leaf page, is: ** ** varint : size of first term ** blob: first term data ** doclist: first doclist ** zero-or-more { ** varint: number of bytes in common with previous term ** varint: number of bytes of new term data (nNew) ** blob: nNew bytes of new term data ** doclist: next doclist ** } ** ** doclist format: ** ** varint: first rowid ** poslist: first poslist ** zero-or-more { ** varint: rowid delta (always > 0) ** poslist: next poslist ** } ** ** poslist format: ** ** varint: size of poslist in bytes multiplied by 2, not including ** this field. Plus 1 if this entry carries the "delete" flag. ** collist: collist for column 0 ** zero-or-more { ** 0x01 byte ** varint: column number (I) ** collist: collist for column I ** } ** ** collist format: ** ** varint: first offset + 2 ** zero-or-more { ** varint: offset delta + 2 ** } ** ** PAGE FORMAT ** ** Each leaf page begins with a 4-byte header containing 2 16-bit ** unsigned integer fields in big-endian format. They are: ** ** * The byte offset of the first rowid on the page, if it exists ** and occurs before the first term (otherwise 0). ** ** * The byte offset of the start of the page footer. If the page ** footer is 0 bytes in size, then this field is the same as the ** size of the leaf page in bytes. ** ** The page footer consists of a single varint for each term located ** on the page. Each varint is the byte offset of the current term ** within the page, delta-compressed against the previous value. In ** other words, the first varint in the footer is the byte offset of ** the first term, the second is the byte offset of the second less that ** of the first, and so on. ** ** The term/doclist format described above is accurate if the entire ** term/doclist data fits on a single leaf page. If this is not the case, ** the format is changed in two ways: ** ** + if the first rowid on a page occurs before the first term, it ** is stored as a literal value: ** ** varint: first rowid ** ** + the first term on each page is stored in the same way as the ** very first term of the segment: ** ** varint : size of first term ** blob: first term data ** ** 5. Segment doclist indexes: ** ** Doclist indexes are themselves b-trees, however they usually consist of ** a single leaf record only. The format of each doclist index leaf page ** is: ** ** * Flags byte. Bits are: ** 0x01: Clear if leaf is also the root page, otherwise set. ** ** * Page number of fts index leaf page. As a varint. ** ** * First rowid on page indicated by previous field. As a varint. ** ** * A list of varints, one for each subsequent termless page. A ** positive delta if the termless page contains at least one rowid, ** or an 0x00 byte otherwise. ** ** Internal doclist index nodes are: ** ** * Flags byte. Bits are: ** 0x01: Clear for root page, otherwise set. ** ** * Page number of first child page. As a varint. ** ** * Copy of first rowid on page indicated by previous field. As a varint. ** ** * A list of delta-encoded varints - the first rowid on each subsequent ** child page. ** ** 6. Tombstone Hash Page ** ** These records are only ever present in contentless_delete=1 tables. ** There are zero or more of these associated with each segment. They ** are used to store the tombstone rowids for rows contained in the ** associated segments. ** ** The set of nHashPg tombstone hash pages associated with a single ** segment together form a single hash table containing tombstone rowids. ** To find the page of the hash on which a key might be stored: ** ** iPg = (rowid % nHashPg) ** ** Then, within page iPg, which has nSlot slots: ** ** iSlot = (rowid / nHashPg) % nSlot ** ** Each tombstone hash page begins with an 8 byte header: ** ** 1-byte: Key-size (the size in bytes of each slot). Either 4 or 8. ** 1-byte: rowid-0-tombstone flag. This flag is only valid on the ** first tombstone hash page for each segment (iPg=0). If set, ** the hash table contains rowid 0. If clear, it does not. ** Rowid 0 is handled specially. ** 2-bytes: unused. ** 4-bytes: Big-endian integer containing number of entries on page. ** ** Following this are nSlot 4 or 8 byte slots (depending on the key-size ** in the first byte of the page header). The number of slots may be ** determined based on the size of the page record and the key-size: ** ** nSlot = (nByte - 8) / key-size */ /* ** Rowids for the averages and structure records in the %_data table. */ /* ** Macros determining the rowids used by segment leaves and dlidx leaves ** and nodes. All nodes and leaves are stored in the %_data table with large ** positive rowids. ** ** Each segment has a unique non-zero 16-bit id. ** ** The rowid for each segment leaf is found by passing the segment id and ** the leaf page number to the FTS5_SEGMENT_ROWID macro.

Only ** the P1, P2 and P5 operands of this opcode are also used, and are called ** This.P1, This.P2 and This.P5. ** ** This opcode helps to optimize IN operators on a multi-column index ** where the IN operator is on the later terms of the index by avoiding ** unnecessary seeks on the btree, substituting steps to the next row ** of the b-tree instead. A correct answer is obtained if this opcode ** is omitted or is a no-op. ** ** The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which ** is the desired entry that we want the cursor SeekGE.P1 to be pointing ** to.

    2. If the cursor is left pointing to a row that is before the target ** row, even after making as many as This.P1 calls to ** sqlite3BtreeNext(), then also fall through into OP_SeekGE. ** **
    3. If the cursor is left pointing at the target row, either because it ** was at the target row to begin with or because one or more ** sqlite3BtreeNext() calls moved the cursor to the target row, ** then jump to This.P2.., ** **
    4. If the cursor started out before the target row and a call to ** to sqlite3BtreeNext() moved the cursor off the end of the index ** (indicating that the target row definitely does not exist in the ** btree) then jump to SeekGE.P2, ending the loop. ** **
    5. If the cursor ends up on a valid row that is past the target row ** (indicating that the target row does not exist in the btree) then ** jump to SeekOP.P2 if This.P5==0 or to This.P2 if This.P5>0. **

For // ** example, if the SQL is this: // ** // ** SELECT * FROM t1, t2, t3 WHERE ...; // ** // ** Then the code generated is conceptually like the following: // ** // ** foreach row1 in t1 do \ Code generated // ** foreach row2 in t2 do |-- by sqlite3WhereBegin() // ** foreach row3 in t3 do / // ** ... // ** end \ Code generated // ** end |-- by sqlite3WhereEnd() // ** end / // ** // ** Note that the loops might not be nested in the order in which they // ** appear in the FROM clause if a different order is better able to make // ** use of indices. Note also that when the IN operator appears in // ** the WHERE clause, it might result in additional nested loops for // ** scanning through all values on the right-hand side of the IN. // ** // ** There are Btree cursors associated with each table. t1 uses cursor // ** number pTabList->a[0].iCursor. t2 uses the cursor pTabList->a[1].iCursor. // ** And so forth. This routine generates code to open those VDBE cursors // ** and sqlite3WhereEnd() generates the code to close them. // ** // ** The code that sqlite3WhereBegin() generates leaves the cursors named // ** in pTabList pointing at their appropriate entries. The [...] code // ** can use OP_Column and OP_Rowid opcodes on these cursors to extract // ** data from the various tables of the loop. // ** // ** If the WHERE clause is empty, the foreach loops must each scan their // ** entire tables. Thus a three-way join is an O(N^3) operation. But if // ** the tables have indices and there are terms in the WHERE clause that // ** refer to those indices, a complete table scan can be avoided and the // ** code will run much faster. Most of the work of this routine is checking // ** to see if there are indices that can be used to speed up the loop. // ** // ** Terms of the WHERE clause are also used to limit which rows actually // ** make it to the "..." in the middle of the loop. After each "foreach", // ** terms of the WHERE clause that use only terms in that loop and outer // ** loops are evaluated and if false a jump is made around all subsequent // ** inner loops (or around the "..." if the test occurs within the inner- // ** most loop) // ** // ** OUTER JOINS // ** // ** An outer join of tables t1 and t2 is conceptually coded as follows: // ** // ** foreach row1 in t1 do // ** flag = 0 // ** foreach row2 in t2 do // ** start: // ** ... // ** flag = 1 // ** end // ** if flag==0 then // ** move the row2 cursor to a null row // ** goto start // ** fi // ** end // ** // ** ORDER BY CLAUSE PROCESSING // ** // ** pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause // ** if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement // ** if there is one.

For example, with the ** schema: ** ** CREATE TABLE t1(a, b, c, d, e, f, g); ** ** the statement: ** ** SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e; ** ** is transformed to: ** ** SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM ( ** SELECT a, e, c, d, b FROM t1 ORDER BY c, d ** ) ORDER BY e; ** ** The flattening optimization is disabled when processing this transformed ** SELECT statement. This allows the implementation of the window function ** (in this case max()) to process rows sorted in order of (c, d), which ** makes things easier for obvious reasons. More generally: ** ** * FROM, WHERE, GROUP BY and HAVING clauses are all moved to ** the sub-query. ** ** * ORDER BY, LIMIT and OFFSET remain part of the parent query. ** ** * Terminals from each of the expression trees that make up the ** select-list and ORDER BY expressions in the parent query are ** selected by the sub-query. For the purposes of the transformation, ** terminals are column references and aggregate functions. ** ** If there is more than one window function in the SELECT that uses ** the same window declaration (the OVER bit), then a single scan may ** be used to process more than one window function. For example: ** ** SELECT max(b) OVER (PARTITION BY c ORDER BY d), ** min(e) OVER (PARTITION BY c ORDER BY d) ** FROM t1; ** ** is transformed in the same way as the example above. However: ** ** SELECT max(b) OVER (PARTITION BY c ORDER BY d), ** min(e) OVER (PARTITION BY a ORDER BY b) ** FROM t1; ** ** Must be transformed to: ** ** SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM ( ** SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM ** SELECT a, e, c, d, b FROM t1 ORDER BY a, b ** ) ORDER BY c, d ** ) ORDER BY e; ** ** so that both min() and max() may process rows in the order defined by ** their respective window declarations. ** ** INTERFACE WITH SELECT.C ** ** When processing the rewritten SELECT statement, code in select.c calls ** sqlite3WhereBegin() to begin iterating through the results of the ** sub-query, which is always implemented as a co-routine. It then calls ** sqlite3WindowCodeStep() to process rows and finish the scan by calling ** sqlite3WhereEnd(). ** ** sqlite3WindowCodeStep() generates VM code so that, for each row returned ** by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked. ** When the sub-routine is invoked: ** ** * The results of all window-functions for the row are stored ** in the associated Window.regResult registers. ** ** * The required terminal values are stored in the current row of ** temp table Window.iEphCsr. ** ** In some cases, depending on the window frame and the specific window ** functions invoked, sqlite3WindowCodeStep() caches each entire partition ** in a temp table before returning any rows. In other cases it does not. ** This detail is encapsulated within this file, the code generated by ** select.c is the same in either case. ** ** BUILT-IN WINDOW FUNCTIONS ** ** This implementation features the following built-in window functions: ** ** row_number() ** rank() ** dense_rank() ** percent_rank() ** cume_dist() ** ntile(N) ** lead(expr [, offset [, default]]) ** lag(expr [, offset [, default]]) ** first_value(expr) ** last_value(expr) ** nth_value(expr, N) ** ** These are the same built-in window functions supported by Postgres. ** Although the behaviour of aggregate window functions (functions that ** can be used as either aggregates or window functions) allows them to ** be implemented using an API, built-in window functions are much more ** esoteric. Additionally, some window functions (e.g. nth_value()) ** may only be implemented by caching the entire partition in memory. ** As such, some built-in window functions use the same API as aggregate ** window functions and some are implemented directly using VDBE ** instructions. Additionally, for those functions that use the API, the ** window frame is sometimes modified before the SELECT statement is ** rewritten. For example, regardless of the specified window frame, the ** row_number() function always uses: ** ** ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW ** ** See sqlite3WindowUpdate() for details. ** ** As well as some of the built-in window functions, aggregate window ** functions min() and max() are implemented using VDBE instructions if ** the start of the window frame is declared as anything other than ** UNBOUNDED PRECEDING. */ // C documentation // // /* // ** Add a single OP_Explain opcode that describes a Bloom filter. // ** // ** Or if not processing EXPLAIN QUERY PLAN and not in a SQLITE_DEBUG and/or // ** SQLITE_ENABLE_STMT_SCANSTATUS build, then OP_Explain opcodes are not // ** required and this routine is a no-op. // ** // ** If an OP_Explain opcode is added to the VM, its address is returned. // ** Otherwise, if no OP_Explain is coded, zero is returned. // */ func _sqlite3WhereExplainBloomFilter(tls *libc.TLS, pParse uintptr, pWInfo uintptr, pLevel uintptr) (r int32) { bp := tls.Alloc(160) defer tls.Free(160) var db, pItem, pLoop, pTab, v, z, zMsg uintptr var i, ret int32 var _ /* str at bp+0 */ TStrAccum var _ /* zBuf at bp+32 */ [100]int8 _, _, _, _, _, _, _, _, _ = db, i, pItem, pLoop, pTab, ret, v, z, zMsg ret = 0 pItem = (*TWhereInfo)(unsafe.Pointer(pWInfo)).FpTabList + 8 + uintptr((*TWhereLevel)(unsafe.Pointer(pLevel)).FiFrom)*80 v = (*TParse)(unsafe.Pointer(pParse)).FpVdbe /* VM being constructed */ db = (*TParse)(unsafe.Pointer(pParse)).Fdb /* Initial space for EQP output string */ _sqlite3StrAccumInit(tls, bp, db, bp+32, int32(100), int32(SQLITE_MAX_LENGTH)) (**(**TStrAccum)(__ccgo_up(bp))).FprintfFlags = uint8(SQLITE_PRINTF_INTERNAL) Xsqlite3_str_appendf(tls, bp, __ccgo_ts+25101, libc.VaList(bp+144, pItem)) pLoop = (*TWhereLevel)(unsafe.Pointer(pLevel)).FpWLoop if (*TWhereLoop)(unsafe.Pointer(pLoop)).FwsFlags&uint32(WHERE_IPK) != 0 { pTab = (*TSrcItem)(unsafe.Pointer(pItem)).FpSTab if int32((*TTable)(unsafe.Pointer(pTab)).FiPKey) >= 0 { Xsqlite3_str_appendf(tls, bp, __ccgo_ts+24870, libc.VaList(bp+144, (**(**TColumn)(__ccgo_up((*TTable)(unsafe.Pointer(pTab)).FaCol + uintptr((*TTable)(unsafe.Pointer(pTab)).FiPKey)*16))).FzCnName)) } else { Xsqlite3_str_appendf(tls, bp, __ccgo_ts+25122, 0) } } else { i = int32((*TWhereLoop)(unsafe.Pointer(pLoop)).FnSkip) for { if !(i < int32((*(*struct { FnEq Tu16 FnBtm Tu16 FnTop Tu16 FnDistinctCol Tu16 FpIndex uintptr FpOrderBy uintptr })(unsafe.Pointer(pLoop + 24))).FnEq)) { break } z = _explainIndexColumnName(tls, (*(*struct { FnEq Tu16 FnBtm Tu16 FnTop Tu16 FnDistinctCol Tu16 FpIndex uintptr FpOrderBy uintptr })(unsafe.Pointer(pLoop + 24))).FpIndex, i) if i > int32((*TWhereLoop)(unsafe.Pointer(pLoop)).FnSkip) { Xsqlite3_str_append(tls, bp, __ccgo_ts+24859, int32(5)) } Xsqlite3_str_appendf(tls, bp, __ccgo_ts+24870, libc.VaList(bp+144, z)) goto _1 _1: ; i = i + 1 } } Xsqlite3_str_append(tls, bp, __ccgo_ts+6474, int32(1)) zMsg = _sqlite3StrAccumFinish(tls, bp) ret = _sqlite3VdbeAddOp4(tls, v, int32(OP_Explain), _sqlite3VdbeCurrentAddr(tls, v), (*TParse)(unsafe.Pointer(pParse)).FaddrExplain, 0, zMsg, -int32(7)) return ret } // C documentation // // /* // ** These routines walk (recursively) an expression tree and generate // ** a bitmask indicating which tables are used in that expression // ** tree. // ** // ** sqlite3WhereExprUsage(MaskSet, Expr) -> // ** // ** Return a Bitmask of all tables referenced by Expr.

The only // ** exceptional case is: // ** // ** ROWS BETWEEN FOLLOWING AND UNBOUNDED FOLLOWING // ** // ** ... loop started by sqlite3WhereBegin() ... // ** if( new partition ){ // ** Gosub flush // ** } // ** Insert new row into eph table. // ** if( first row of partition ){ // ** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // ** regStart = // ** }else{ // ** AGGSTEP // ** } // ** } // ** flush: // ** AGGSTEP // ** while( 1 ){ // ** if( (regStart--)<=0 ){ // ** AGGINVERSE // ** if( eof ) break // ** } // ** RETURN_ROW // ** } // ** while( !eof csrCurrent ){ // ** RETURN_ROW // ** } // ** // ** Also requiring special handling are the cases: // ** // ** ROWS BETWEEN PRECEDING AND PRECEDING // ** ROWS BETWEEN FOLLOWING AND FOLLOWING // ** // ** when (expr1 < expr2). This is detected at runtime, not by this function. // ** To handle this case, the pseudo-code programs depicted above are modified // ** slightly to be: // ** // ** ... loop started by sqlite3WhereBegin() ... // ** if( new partition ){ // ** Gosub flush // ** } // ** Insert new row into eph table. // ** if( first row of partition ){ // ** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // ** regEnd = // ** regStart = // ** if( regEnd < regStart ){ // ** RETURN_ROW // ** delete eph table contents // ** continue // ** } // ** ... // ** // ** The new "continue" statement in the above jumps to the next iteration // ** of the outer loop - the one started by sqlite3WhereBegin(). // ** // ** The various GROUPS cases are implemented using the same patterns as // ** ROWS. The VM code is modified slightly so that: // ** // ** 1. The else branch in the main loop is only taken if the row just // ** added to the ephemeral table is the start of a new group. In // ** other words, it becomes: // ** // ** ... loop started by sqlite3WhereBegin() ... // ** if( new partition ){ // ** Gosub flush // ** } // ** Insert new row into eph table. // ** if( first row of partition ){ // ** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // ** regEnd = // ** regStart = // ** }else if( new group ){ // ** ... // ** } // ** } // ** // ** 2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or // ** AGGINVERSE step processes the current row of the relevant cursor and // ** all subsequent rows belonging to the same group. // ** // ** RANGE window frames are a little different again. As for GROUPS, the // ** main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE // ** deal in groups instead of rows. As for ROWS and GROUPS, there are three // ** basic cases: // ** // ** RANGE BETWEEN PRECEDING AND FOLLOWING // ** // ** ... loop started by sqlite3WhereBegin() ... // ** if( new partition ){ // ** Gosub flush // ** } // ** Insert new row into eph table. // ** if( first row of partition ){ // ** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // ** regEnd = // ** regStart = // ** }else{ // ** AGGSTEP // ** while( (csrCurrent.key + regEnd) < csrEnd.key ){ // ** RETURN_ROW // ** while( csrStart.key + regStart) < csrCurrent.key ){ // ** AGGINVERSE // ** } // ** } // ** } // ** } // ** flush: // ** AGGSTEP // ** while( 1 ){ // ** RETURN ROW // ** if( csrCurrent is EOF ) break; // ** while( csrStart.key + regStart) < csrCurrent.key ){ // ** AGGINVERSE // ** } // ** } // ** } // ** // ** In the above notation, "csr.key" means the current value of the ORDER BY // ** expression (there is only ever 1 for a RANGE that uses an FOLLOWING // ** or PRECEDING AND PRECEDING // ** // ** ... loop started by sqlite3WhereBegin() ... // ** if( new partition ){ // ** Gosub flush // ** } // ** Insert new row into eph table. // ** if( first row of partition ){ // ** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // ** regEnd = // ** regStart = // ** }else{ // ** while( (csrEnd.key + regEnd) <= csrCurrent.key ){ // ** AGGSTEP // ** } // ** while( (csrStart.key + regStart) < csrCurrent.key ){ // ** AGGINVERSE // ** } // ** RETURN_ROW // ** } // ** } // ** flush: // ** while( (csrEnd.key + regEnd) <= csrCurrent.key ){ // ** AGGSTEP // ** } // ** while( (csrStart.key + regStart) < csrCurrent.key ){ // ** AGGINVERSE // ** } // ** RETURN_ROW // ** // ** RANGE BETWEEN FOLLOWING AND FOLLOWING // ** // ** ... loop started by sqlite3WhereBegin() ... // ** if( new partition ){ // ** Gosub flush // ** } // ** Insert new row into eph table. // ** if( first row of partition ){ // ** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent) // ** regEnd = // ** regStart = // ** }else{ // ** AGGSTEP // ** while( (csrCurrent.key + regEnd) < csrEnd.key ){ // ** while( (csrCurrent.key + regStart) > csrStart.key ){ // ** AGGINVERSE // ** } // ** RETURN_ROW // ** } // ** } // ** } // ** flush: // ** AGGSTEP // ** while( 1 ){ // ** while( (csrCurrent.key + regStart) > csrStart.key ){ // ** AGGINVERSE // ** if( eof ) break "while( 1 )" loop. // ** } // ** RETURN_ROW // ** } // ** while( !eof csrCurrent ){ // ** RETURN_ROW // ** } // ** // ** The text above leaves out many details.
