Remarks

Argument specified	Type of validation
None	All tables, materialized views, and indexes in the database are validated. The database itself is also validated, including checksum validation.
`owner_name`	All tables, materialized views, and indexes owned by the specified user are validated.
`tbl_name`	The specified table, or materialized view, and all of its indexes, that are owned by the current user are validated.
`owner_name` and `tbl_name`	The specified table, or materialized view, and all of its indexes, that are owned by the specified user are validated.

The values for tbl_name and owner_name are strings and must be enclosed in quotes.

The procedure returns a single column named Messages. Errors returned during validation appear in the column. If validation succeeds without error, the column contains No error detected.

Warning! Validating a table or an entire database should be performed while no connections are making changes to the database; otherwise, errors may be reported indicating some form of database corruption even though no corruption actually exists.

Example

The following statement performs a validation of tables and materialized views owned by DBA:

CALL sa_validate( owner_name = 'DBA' );
