CREATE PROCEDURE [dbo].[usp_getstore_details]
@input VARCHAR(100)
AS  
BEGIN 
    DECLARE @out VARCHAR(100) 
    DECLARE @result INT 

    IF LEN(@input) = 2 
    BEGIN 
        --select  statement here. 
    END 
    ELSE IF @input LIKE '%[0-9]%' 
    BEGIN 
        --select statement here  
    END 
    ELSE  
    BEGIN 
        SET @result = LEN(@input) - LEN(REPLACE(@input, ',', '')) 
        IF @result > 1
        BEGIN 
            --select statement here  
        END 
        ELSE 
        BEGIN 
            --select statement here 
        END 
    END
