When flattening a query of the form "SELECT * FROM (SELECT * FROM tbl WHERE x=?) WHERE y=?", ensure that the final WHERE clause is "x=? AND y=?" instead of "y=? AND x=?". Although it is still not guaranteed, this makes the order in which WHERE clause terms are processed comport more closely to users expectations. check-in: cf7f9e6d user: dan tags: trunk

Inline the relevent parts of sqlite3ExprAlloc() into spanExpr(), for a performance improvement. check-in: fe89225e user: drh tags: trunk
