![ISQL_COMMAND_TIMING option [DBISQL]](arrow-right.gif){kind=icon}
Controls the locking isolation level for Catalog Store tables.
0, 1, 2, or 3
0
Each locking isolation level is defined as follows:
1 Prevent dirty reads. Allow nonrepeatable reads and phantom rows.
2 Prevent dirty reads and guarantee repeatable reads. Allow phantom rows.
3 Serializable. Do not allow dirty reads, guarantee repeatable reads, and do not allow phantom rows.
This option determines the isolation level for tables in the Catalog Store. Sybase IQ always enforces level 3 for tables in the IQ Store. Level 3 is equivalent to ANSI level 4.
