[Execute SQL Task] Error: Executing the query ...

Hi,

Here is my setup:

User Defined Variable:

Tab: General

DELETE FROM TmptblCase WHERE RequestDate > ?

Parameter Mapping:

Result Set:

Error Message:

[Execute SQL Task] Error: Executing the query "DELETE FROM TmptblCase
WHERE       RequestDate > ?" failed with the following error: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

What wrong here?

Regards
