Question

Hi I’m tying to run an alter database statement and keep getting an error:
(this is to go in a script which will run against a number of databases)

SELECT is_broker_enabled FROM sys.databases WHERE name = db_name()

DECLARE @SQL NVARCHAR(1024)


IF (SELECT is_broker_enabled FROM sys.databases WHERE name = db_name()) = 0
BEGIN

    SET @SQL = N'ALTER DATABASE [' + db_name() + '] SET SINGLE_USER WITH ROLLBACK IMMEDIATE';
    SELECT @SQL;
    sp_executesql @SQL;

    SET @SQL = N'ALTER DATABASE [' + db_name() + '] SET ENABLE_BROKER';
    SELECT @SQL;
    sp_executesql @SQL;


    SET @SQL = N'ALTER DATABASE [' + db_name() + '] SET MULTI_USER';
    SELECT @SQL;
    sp_executesql @SQL;

END 

SELECT is_broker_enabled FROM sys.databases WHERE name = db_name()

I keep getting

Msg 102, Level 15, State 1, Line 11
Incorrect syntax near ‘sp_executesql’.
Msg 102, Level 15, State 1, Line 15
Incorrect syntax near ‘sp_executesql’.
Msg 102, Level 15, State 1, Line 20
Incorrect syntax near ‘sp_executesql’.

I’m doing something dumb – but like most syntax problems looking does not give rise to seeing…

Try with the exec keyword, like this:

exec sp_executesql @SQL;

That’s the way how you call another stored procedure from inside a stored procedure (you could also use EXECUTE, which does exactly the same). Take care not to confuse it with the Exec(...) function (see also here).
