Messages with a severity level of 10 or less are informational and indicate problems caused by mistakes in information that a user has entered. Severity levels from 11 through 16 are generated by the user, and can be corrected by the user. Severity levels from 17 through 25 indicate software or hardware errors. When a level 17, 18, or 19 error occurs, you can continue working, although you might not be able to execute a particular statement.

The remains open when the severity level is 19 or less. When the severity level is 20 or greater, the server usually closes the . However, the user can reopen the connection and continue. In both cases, a is generated by the method executing the command.
