(Ticket #2942) This used to not matter // ** until we introduced the group_concat() function. // ** // ** (17) If the subquery is a compound select, then // ** (17a) all compound operators must be a UNION ALL, and // ** (17b) no terms within the subquery compound may be aggregate // ** or DISTINCT, and // ** (17c) every term within the subquery compound must have a FROM clause // ** (17d) the outer query may not be // ** (17d1) aggregate, or // ** (17d2) DISTINCT // ** (17e) the subquery may not contain window functions, and // ** (17f) the subquery must not be the RHS of a LEFT JOIN. // ** (17g) either the subquery is the first element of the outer // ** query or there are no RIGHT or FULL JOINs in any arm // ** of the subquery. (This is a duplicate of condition (27b).) // ** (17h) The corresponding result set expressions in all arms of the // ** compound must have the same affinity. // ** // ** The parent and sub-query may contain WHERE clauses. Subject to // ** rules (11), (13) and (14), they may also contain ORDER BY, // ** LIMIT and OFFSET clauses. The subquery cannot use any compound // ** operator other than UNION ALL because all the other compound // ** operators have an implied DISTINCT which is disallowed by // ** restriction (4). // ** // ** Also, each component of the sub-query must return the same number // ** of result columns. This is actually a requirement for any compound // ** SELECT statement, but all the code here does is make sure that no // ** such (illegal) sub-query is flattened. The caller will detect the // ** syntax error and return a detailed message. // ** // ** (18) If the sub-query is a compound select, then all terms of the // ** ORDER BY clause of the parent must be copies of a term returned // ** by the parent query. // ** // ** (19) If the subquery uses LIMIT then the outer query may not // ** have a WHERE clause. // ** // ** (20) If the sub-query is a compound select, then it must not use // ** an ORDER BY clause. Ticket #3773. We could relax this constraint // ** somewhat by saying that the terms of the ORDER BY clause must // ** appear as unmodified result columns in the outer query. But we // ** have other optimizations in mind to deal with that case. // ** // ** (21) If the subquery uses LIMIT then the outer query may not be // ** DISTINCT. (See ticket [752e1646fc]). // ** // ** (22) The subquery may not be a recursive CTE. // ** // ** (23) If the outer query is a recursive CTE, then the sub-query may not be // ** a compound query. This restriction is because transforming the // ** parent to a compound query confuses the code that handles // ** recursive queries in multiSelect(). // ** // ** (**) We no longer attempt to flatten aggregate subqueries. Was: // ** The subquery may not be an aggregate that uses the built-in min() or // ** or max() functions. (Without this restriction, a query like: // ** "SELECT x FROM (SELECT max(y), x FROM t1)" would not necessarily // ** return the value X for which Y was maximal.) // ** // ** (25) If either the subquery or the parent query contains a window // ** function in the select list or ORDER BY clause, flattening // ** is not attempted. // ** // ** (26) The subquery may not be the right operand of a RIGHT JOIN. // ** See also (3) for restrictions on LEFT JOIN. // ** // ** (27) The subquery may not contain a FULL or RIGHT JOIN unless it // ** is the first element of the parent query. Two subcases: // ** (27a) the subquery is not a compound query. // ** (27b) the subquery is a compound query and the RIGHT JOIN occurs // ** in any arm of the compound query. (See also (17g).) // ** // ** (28) The subquery is not a MATERIALIZED CTE. (This is handled // ** in the caller before ever reaching this routine.) // ** // ** // ** In this routine, the "p" parameter is a pointer to the outer query. // ** The subquery is p->pSrc->a[iFrom]. isAgg is true if the outer query // ** uses aggregates. // ** // ** If flattening is not attempted, this routine is a no-op and returns 0. // ** If flattening is attempted this routine returns 1. // ** // ** All of the expression analysis must occur on both the outer query and // ** the subquery before this routine runs. // */ func _flattenSubquery(tls *libc.TLS, pParse uintptr, p uintptr, iFrom int32, isAgg int32) (r int32) { bp := tls.Alloc(96) defer tls.Free(96) var aCsrMap, db, pItem, pItemTab, pLimit, pNew, pOrderBy, pOrderBy1, pParent, pPrior, pSrc, pSub, pSub1, pSubSrc, pSubitem, pTabToDel, pToplevel, pWhere, zSavedAuthContext, v5 uintptr var i, iNewParent, iParent, ii, isOuterJoin, nSubSrc, v4 int32 var jointype Tu8 var _ /* w at bp+0 */ TWalker var _ /* x at bp+48 */ TSubstContext _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _ = aCsrMap, db, i, iNewParent, iParent, ii, isOuterJoin, jointype, nSubSrc, pItem, pItemTab, pLimit, pNew, pOrderBy, pOrderBy1, pParent, pPrior, pSrc, pSub, pSub1, pSubSrc, pSubitem, pTabToDel, pToplevel, pWhere, zSavedAuthContext, v4, v5 zSavedAuthContext = (*TParse)(unsafe.Pointer(pParse)).FzAuthContext /* VDBE cursor number of the pSub result set temp table */ iNewParent = -int32(1) /* Replacement table for iParent */ isOuterJoin = 0 /* The subquery */ db = (*TParse)(unsafe.Pointer(pParse)).Fdb /* Walker to persist agginfo data */ aCsrMap = uintptr(0) /* Check to see if flattening is permitted.

Later, the calling routine // ** should invoke sqlite3WhereEnd() with the return value of this function // ** in order to complete the WHERE clause processing. // ** // ** If an error occurs, this routine returns NULL. // ** // ** The basic idea is to do a nested loop, one loop for each table in // ** the FROM clause of a select. (INSERT and UPDATE statements are the // ** same as a SELECT with only a single table in the FROM clause.) 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 // // /* // ** If the WHERE_GROUPBY flag is set in the mask passed to sqlite3WhereBegin(), // ** the planner assumes that the specified pOrderBy list is actually a GROUP // ** BY clause - and so any order that groups rows as required satisfies the // ** request. // ** // ** Normally, in this case it is not possible for the caller to determine // ** whether or not the rows are really being delivered in sorted order, or // ** just in some other order that provides the required grouping.
