Error Message:
Msg 10504, Level 16, State 1, Line 1
Cannot create plan guide ‘%.*ls’ because parameter @hints is incorrect. Use N’OPTION ( <query_hint> [ ,…n ] )’.
Severity level:
16.
Description:
This error message appears when you try to create a planguide, but the @hints parameter is incorrect.
Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.
Resolution:
Errors of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be executed this way. The @hints parameter must be provided in the form OPTION (hint1, …hint n)
Versions:
This error message was introduced with SQL Server 2005.
Example(s):
IF OBJECT_ID (‘dbo.t’) IS NOT NULL
DROP TABLE dbo.t;
GO
CREATE TABLE dbo.t
(
c1 int
);
GO
EXEC sp_create_plan_guide
@name = ‘Guide1’,
@stmt = ‘SELECT TOP 1
*
FROM
dbo.t
ORDER BY
c1 DESC’,
@type = ‘SQL’,
@module_or_batch = NULL,
@params = NULL,
@hints = ‘MAXDOP 1’;
EXEC sp_control_plan_guide ‘DROP’, ‘Guide1’;
Remarks:
In the above example we try to create a planguide. Because the @hints parameter does not meet the required form, the error is raised.
