Introduction Db2 OR operator. The OR operator is a logical operator that combines two Boolean expressions or predicates. the OR operator is often used in the WHERE clause of the SELECT, UPDATE, and DELETE statements to specify a search condition for rows to be selected, updated, and deleted. Here is the syntax of the OR operator:

If a database object such as a table, view, or index is not fully qualified in a dynamic SQL statement, it will be implicitly qualified with the single authentication ID that the TP monitor is executing under, rather than user's ID. Any use of DB2 COMMIT or ROLLBACK statements for transactions that are not LOCAL will be rejected.
