+** The sqlite3session_config() interface is not threadsafe. If it is invoked

+** The first argument to the sqlite3session_config() function must be one

+** passed as the second argument must point to a value of type (int).
+** If this value is greater than 0, it is used as the new streaming data
+** chunk size for both input and output. Before returning, the (int) value
+** pointed to by pArg is set to the final value of the streaming interface

+** then throughout the query replace all other occurrences of COLUMN
+** with CONSTANT within the WHERE clause.
+**
+** For example, the query:
+**
+** SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=t1.a AND t3.c=t2.b
+**
+** Is transformed into
+**

+**
+** Return true if any transformations where made and false if not.
+**
+** Implementation note: Constant propagation is tricky due to affinity
+** and collating sequence interactions. Consider this example:
+**
+** CREATE TABLE t1(a INT,b TEXT);
+** INSERT INTO t1 VALUES(123,'0123');
+** SELECT * FROM t1 WHERE a=123 AND b=a;
+** SELECT * FROM t1 WHERE a=123 AND b=123;
+**
+** The two SELECT statements above should return different answers. b=a
+** is alway true because the comparison uses numeric affinity, but b=123
+** is false because it uses text affinity and '0123' is not the same as '123'.
+** To work around this, the expression tree is not actually changed from
+** "b=a" to "b=123" but rather the "a" in "b=a" is tagged with EP_FixedCol
+** and the "123" value is hung off of the pLeft pointer. Code generator
+** routines know to generate the constant "123" instead of looking up the
+** column value. Also, to avoid collation problems, this optimization is
+** only attempted if the "a=123" term uses the default BINARY collation.

+/*
+** SELECT REWRITING
+**
+** Any SELECT statement that contains one or more window functions in
+** either the select list or ORDER BY clause (the only two places window
+** functions may be used) is transformed by function sqlite3WindowRewrite()
+** in order to support window function processing. 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 funtions) 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.
