You must have either DBA or VALIDATE authority to validate a database.
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.
Connect to the database as a user with DBA authority.
In the left pane, select the database.
From the File menu, choose Validate Database.
Follow the instructions in the Validate Database Wizard.
You can also access the Validate Database Wizard from within Sybase Central using any of the following methods:
Right-clicking the database, and choosing Validate Database.
Selecting the database, and choosing Tools » SQL Anywhere 11 » Validate Database.
Execute the sa_validate stored procedure:
The procedure returns a single column, named Messages. If all tables are valid, the column contains
No errors detected.
For more information, see sa_validate system procedure.
Run the dbvalid utility:
dbvalid -c "connection-string"
If you are checking the validity of a backup copy, run the database in read-only mode so that it is not modified in any way. You can only do this if there were no transactions in progress during the backup. See -r server option.
