Devart.Data.Oracle Namespace / OracleQueueTable Class / PurgeQueueTable Method / PurgeQueueTable(String,Boolean) Method
Specifies the purge condition to use when purging the queue table. The purge condition must be in the format of a SQL WHERE clause, and it is case-sensitive. The condition is based on the columns of aq$queue_table view.
If block is true, then an exclusive lock on all the queues in the queue table is held while purging the queue table. This will cause concurrent enqueuers and dequeuers to block while the queue table is purged. The purge call always succeeds if block is true. This will not block enqueuers and dequeuers, but it can cause the purge to fail with an error during high concurrency times.
