Question

I am trying to create a stored procedure in SQL Server 2008 where I am trying to replicate a simple query of

SELECT Col1, Col2 
FROM Table
WHERE Col1 LIKE 'A%'
    OR Col1 LIKE 'B%'
    OR Col1 LIKE 'C%'

as

CREATE PROCEDURE usp_MySP
    @ColValues varchar(100) = NULL
AS
SELECT Col1, Col2 
FROM Table
WHERE (@ColValues IS NULL OR Col1 LIKE (????))

Unable to replace ??. Basically I want to use LIKE with IN / OR. Any help?

Answer 1

If the number of parameters is unknown, then you will need to do a table operation. Basically something like

select
    col1,
    col2
from
    Table t
    inner join MyParameters p on (t.Col1 like p.Query)

In order to generate table MyParameters, you can either construct it in your code, or use the new table-valued parameters in 2008.
