mysql - ON DUPLICATE KEY UPDATE ... with WHERE or subselection? -


i bit concerned 1 of mysql queries... following query receives variable $db_id... if row primary key exists query performs update.

$this->db->query("  insert         modules_text                                              (   module_id,                                                 module_content,                                                 module_index                                             )                          values              (   '{$db_id}',                                                 '{$content['text']}',                                                 '{$index}'                                             )                          on duplicate key                         update            module_content    = '{$content['text']}',                                         module_index      = '{$index}'                      "); 

now thing concerns me... there no relation if affected rows belong user. add statement update part or first make subselecion of rows permitted affected. like:

[...]             on duplicate key             update            module_content    = '{$content['text']}',                             module_index      = '{$index}'                        module_post_id    = '{$post]}' 

is somehow possible... until didnt find solution... appreciated... lot!!!!!

saludos sacha!

this isn't how on duplicate key works. update portion of insert occur if there's match unique key(s) or primary key table. (i.e.: unique/primary key(s) clause.)

see full mysql docs more information.
