| 16:39 | Remove the EXCLUSIVE and CONCURRENT tokens from the tokenizer. Let the BEGIN statement be followed by an ID, but throw a syntax error if the ID is anything other than EXCLUSIVE or CONCURRENT. file: [694f5227] check-in: [c0bf92ec] user: drh branch: begin-concurrent, size: 1463 | |
|
2014-01-21
| ||
| 00:19 | Add support for the LEVEL pseudo-column in the recursive part of a common table expression. LEVEL has the value of 1 on the first iteration and successively larger integer values of subsequent iterations. It cannot have a table qualifier. Actual columns named "level" can still be accessed by including the table name qualifier. file: [9d876880] check-in: [cc1cb321] user: drh branch: level-pseudocolumn, size: 1403 | |

| ||
| 03:54 | Optimizations to the SQL language grammar that result in a small size reduction and speed increase. file: [9eb448a5] check-in: [cb5d1f83] user: drh branch: trunk, size: 1343 | |
|
2013-11-21
| ||
| 14:44 | Remove the obsolete TK_CONST_FUNC token type. file: [87ca6123] check-in: [9b4217f0] user: drh branch: trunk, size: 1283 | |
|
2009-09-23
| ||
| 02:29 | 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. file: [17dc593f] check-in: [98853f61] user: drh branch: trunk, size: 1343 | |
|
2009-09-22
| ||
| 20:08 | 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. file: [08eb3bdf] check-in: [3fc938c9] user: drh branch: trunk, size: 1283 | |
|
2008-08-20
| ||
| 16:35 | Refactor the name resolution procedures in the code generator. (CVS 5569) file: [215333be] check-in: [daf730d1] user: drh branch: trunk, size: 1163 | |
|
2008-08-08
| ||
| 14:19 | 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) file: [48a2ffae] check-in: [4cedc641] user: drh branch: trunk, size: 1168 | |
|
2005-11-24
| ||
| 22:22 | 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) file: [701697fa] check-in: [2dfc9863] user: drh branch: trunk, size: 1229 Added | |
