ilDBOracle::in | ( | $a_field, | |

$a_type = "" |
|||
) |
Overwritten implementation of $ilDB->in
to avoid ORA-01795 (maximum number of expressions in a list is 1000)
This implementation rewrites the in clause to field IN (1,2,3,...,1000) OR field IN (1000,1001,...,2000)
Example: $ids = array(10,12,18); $st = $ilDB->prepare("SELECT * FROM table ". "WHERE ".$ilDB->in("id", $ids), $ilDB->addTypesToArray($types, "integer", count($ids))); $set = $ilDB->execute($st, $ids);
