X-Git-Tag: version-3.46.0~123
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=43a511927d1656ae73fdb808abdbc61d836b9668;p=thirdparty%2Fsqlite.git

Add the "VALUES-as-coroutine" optimization.  Large VALUES clauses on an
INSERT, for example, prepare and run in about half the time and with half
the memory.  This check-in also includes enhancements to the internal
sqlite3ExprIsConstant() routine to recognize pure SQL functions as constant
if they have constant arguments.
