[PATCH] PDO::FETCH_2D

Hi! As per my rfd from 2007-11-14, I prepared a FETCH_2D (work title) patch - where a row result consists of a two-dimensional hash, the first dimension being the table name, the second the field name. Summary: I propose to rearrange FETCH mode constants, such that FETCH_NUM, FETCH_ASSOC and (new) FETCH_2D are bitwise combineable: FETCH_ASSOC | FETCH_NUM = FETCH_BOTH FETCH_2D | FETCH_NUM = FETCH_2D_NUM FETCH_2D is the "core" of my proposal. It's like the ATTR_FETCH_TABLE_NAMES, enhanced in arrays. Columns are to be found on the second level: $result[tablename][columname] Columns that don't result from a table are added to a "null base" (work title). The default "null base" is the first level array: $result[computedcolumn] The connection attribute ATTR_2D_NULLBASE (work title) defines an alternative "null base": $result[nullbase][computedcolumn] FETCH_2D should be combineable with FETCH_ASSOC and/or FETCH_NUM. The corresponding entries are added to the "null base" (a reference). Status: The attached patch against CVS PHP_5_3 supports the described functionality with pdo_mysql and pdo_firebird (my primary). Please let me know if I'm on a totally wrong path. HPO
