Question

I ‘ve used the Query Builder tool of Visual Studio 2008 to build a stored procedure. This is the preview script:

IF EXISTS (SELECT * 
             FROM sysobjects 
            WHERE name = 'SelectQuery' AND user_name(uid) = 'dbo')
    DROP PROCEDURE dbo.SelectQuery
GO

CREATE PROCEDURE dbo.SelectQuery
(
    @StudentID int
)
AS
    SET NOCOUNT ON;
SELECT        StudentID, StudentName, StudentPhone, StudentAddress, 
              StudentBirthDay, StudentDescription, StudentStatus
FROM            tbl_Student
WHERE        (StudentID LIKE '%' + @StudentID + '%')
GO

But when I tried to execute it, I got an error:

Error Message: Conversion fail when converting the value '%' to datatype int.

Please help me!

Answer 1

You want to find rows where @StudentID is a substring of StudentID? If so

WHERE StudentID LIKE '%' + cast(@StudentID as varchar(10)) + '%'

Should work.
