DatabaseOracle::limitResult | ( | $sql, | |

Construct a LIMIT query with optional offset.
This is used for query pages. The SQL should be adjusted so that only the first $limit rows are returned. If $offset is provided as well, then the first $offset rows should be discarded, and the next $limit rows should be returned. If the result of the query is not ordered, then the rows to be returned are theoretically arbitrary.
$sql is expected to be a SELECT, if that makes a difference.
The version provided by default works in MySQL and SQLite. It will very likely need to be overridden for most other DBMSes.
