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?

CREATE PROCEDURE Search_Project_Name
(@in_project_name_pattern VARCHAR(100))
AS
SELECT project_name
FROM Project_Groups
WHERE project_name
LIKE '%' + @in_project_name_pattern + '%';

But then why are you putting something this simple in a procedure and not just using the LIKE predicate?

...

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
