SQL Maintenance
If you want to use integrated security when you are using sqlmaint, you do not specify anything for the username and password.
If you are not using integrated security, you may need to include the username and password in double quotes.

Validate the output

After running sqlmaint, you should check the output to validate that it worked correctly and that any dbccs performed did not generate an error.
If it runs correctly, you will only see the output generated by the dbccs that shows what tasks were performed.
When running sqlmaint, Microsoft recommends that you DO NOT use the dbcc newalloc command or the dbcc textalloc command. This is because they are planning on getting rid of the command.

Here are some examples of how you might use sqlmaint.exe to accomplish various maintenance tasks based on specific conditions.
