SNAPSHOT_CONTAINER table function

Returns container configuration information from a table space snapshot.

Note: This table function has been deprecated and replaced by the SNAPCONTAINER administrative view and SNAP_GET_CONTAINER_V91 table function - Retrieve tablespace_container logical data group snapshot information


>>-SNAPSHOT_CONTAINER--(--dbname--,--dbpartitionnum--)---------><

The schema is SYSPROC.

Table function parameters

dbname: An input argument of type VARCHAR(255) that specifies a valid database name in the same instance as the currently connected database when calling this function. Specify a database name that has a directory entry type of either "Indirect" or "Home", as returned by the LIST DATABASE DIRECTORY command. Specify the null value to take the snapshot from the currently connected database.
dbpartitionnum: An input argument of type INTEGER that specifies a valid database partition number. Specify -1 for the current database partition, or -2 for all active database partitions. An active database partition is a partition where the database is available for connection and use by applications.
If the null value is specified, -1 is set implicitly.

If both parameters are set to NULL, the snapshot will be taken only if a file has not previously been created by the SNAPSHOT_FILEW stored procedure for the corresponding snapshot API request type.
