Interface.
PURGEDATA table [IGNORE_TRIGGER] [NOLOG]
Syntax Description of PURGEDATA
table
is the name of the table from which to purge the data. See “Database Object Names” (page 228).
Considerations for PURGEDATA
• You must have SELECT/DELETE privileges on the table.
• table-name can be either a table name or a materialized view name.
• If table-name is a materialized view name, the IGNORE_TRIGGER is not supported and
will be ignored if specified.
• If the NOLOG option is not specified, an error is returned if PURGEDATA tries to purge a
table that has a materialized view defined on it.
• If the NOLOG option is not specified, an error is returned if PURGEDATA tries to purge a
materialized view that has a materialized view defined on it.
• Errors are returned if table cannot be accessed or if a resource or file system problem causes
the delete to fail.

Examples of PURGEDATA
