drh	6a2fe09387	Generalize the IS and IS NOT operators so that their right-hand side can be ... an arbitrary expression and not simple the constant NULL. They work like = and <> except that NULL values compare equal to one another an unequal to everything else. FossilOrigin-Name: 98853f6104076c50ea92175e17a3254bfbbd4619	2009-09-23 02:29:36 +00:00
drh	7ba5bc5bf2	Factor the UMINUS and UPLUS tokens out of the parser so that the parser ... tables can go back to using 8-bit values instead of 16-bit values. FossilOrigin-Name: 3fc938c961fd7810594224b91a2d6e1ac9e48084	2009-09-22 20:08:34 +00:00

drh	200a81dcb5	Disallow the ON CONFLICT clause on CHECK constraints. The syntax used to be ... allowed but never worked, so this should not present compatibility problems. Other internal grammar simplifications. (CVS 5546) FossilOrigin-Name: 4cedc641ed39982ae8cbb9200aa1e2f37c878b73	2008-08-08 14:19:41 +00:00
drh	fa3b19ef3d	Reduce the number of distinct token symbols in the parser so that the parser ... can store tokens in a single byte and thus be smaller in size. (CVS 2776) FossilOrigin-Name: 2dfc9863919c9eb1fd1064ab2817d752dd7f9293	2005-11-24 22:22:29 +00:00
