Avoiding Trouble with Lower Compatibility Modes

Avoiding Trouble with Lower Compatibility Modes

If you have a database that’s been upgraded from SQL Server 6.5 to a newer version (like 7 or 2000), but it’s still in compatibility mode 65, you can’t use keywords that don’t exist in this compatibility mode. One example of such a keyword is TOP. Look at the following SQL statement:

 SELECT TOP 10 * FROM My65Table ORDER BY 1

If this statement is executed in a database with compatibility mode 65, the following error message will be generated:

 Server: Msg 170, Level 15, State 1, Line 1Line 1: Incorrect syntax near '10'.

size=3>
To use TOP with a table in the upgraded 6.5 database, execute the command from another database in a higher compatibility mode, i.e. master:

 USE masterGOSELECT TOP 10 * FROM .dbo.My65Table ORDER BY 1

size=3>
