Stored procedure in Where clause

  • Hi,

    below is the query to display the project_name where project_name matches the condition.

    select project_name from Groups

    where project_name like '%20%Catalog%'

    below is the stored procedure using for search string.

    create procedure dbo.STORED_PROC_NAME

    (

    @sstrg varchar(100)

    )

    as

    begin

    set nocount on;

    --declare @strg varchar(100) = 'Catalog',

    set @sstrg = '%' + REPLACE( @sstrg, '*', '%') + '%'

    SELECT project_name

    FROM groups

    WHERE project_name like @sstrg

    end

    i want to execute the same query with stored procedure

    select project_name from Groups

    where project_name like (EXEC STORED_PROC_NAME '%20%Catalog%')

    Please help.

  • The stored procedure returns the result set you want - why complicate it (and double the execution time)?

    You may have simplified things a little to help - in which case, you could run the results of the stored procedure into a #temp table and join to it in your query:

    CREATE TABLE #Projects (project_name VARCHAR(stringsize))

    INSERT INTO #Projects (project_name)

    EXEC STORED_PROC_NAME '%20%Catalog%'

    SELECT g.project_name

    FROM Groups g

    INNER JOIN #Projects p

    ON p.project_name = g.project_name

    In the early days, we had to load parameters into registers in the hardware. Why are you still doing that with local variables?

    ...

    Oh those old days,

    They gone away.

    But we sometimes do need this way,

    To stop a proc to sniff the lot

    So, query plan is what we thought

    :hehe:
