Hi friends
I expect the following query output.
Select EmpId,EmpCode From Emp Where EmpId In(1,2,3)

Alter FUNCTION [dbo].[fnGetEmpCode]
(
@ParamStr Varchar(100)
)
RETURNS TABLE
AS
RETURN
--Select EmpId,EmpCode From Emp Where EmpId In(1,2,3)
Select EmpId,EmpCode From Emp Where EmpId In(@ParamStr)

--------------------------------
--Declare @ParamStr As Varchar(100)
--Set @ParamStr='1,2,3'
--Select * From dbo.fnGetEmpCode(@ParamStr)

I want to pass a set of emp ids as parameter. I dont know how to pass it, as an array or else as string parameter. The column EmpId is Int.
Plz help.

try like this


DECLARE @ParamStr VARCHAR(256)
SET @ParamStr = '1,2,3'

Select EmpId,EmpCode From Emp Where  '%,' + @ParamStr+ ',%' LIKE '%,' + CAST( EmpId   AS VARCHAR(255)) +',%' 

exec('Select EmpId,EmpCode From Emp Where  CAST( EmpId AS VARCHAR(255)) in('+@ParamStr+')')

Select EmpId,EmpCode From Emp Where  patindex('%,' + CAST( EmpId  AS VARCHAR(255)) +',%',','+@ParamStr+',' )>0
