Hi
I have the below query and need the best query to optimize the requirement


SELECT DISTINCT product_id  FROM fact_sales
WHERE (agent_id=1 AND product_code in (1)) 
AND product_id IN
(SELECT DISTINCT product_id FROM fact_sales
WHERE (agent_id=2 AND product_code in (3))
AND product_id IN
(SELECT DISTINCT product_id FROM fact_sales
WHERE (agent_id=3 AND product_code in (2))
AND product_id IN(
SELECT DISTINCT product_id FROM fact_sales
WHERE (agent_id=4 AND product_code in (1)))))

THANKS

below my table syntax

CREATE TABLE [dbo].[fact_sales](
[sales_id] [bigint] IDENTITY(1,1) NOT NULL,
[Product_ID] [bigint] NOT NULL,
[agent_id] [int] NOT NULL,
[product_code] [varchar](50) NULL,
[created_by] [int] NULL,
[created_date] [datetime] NOT NULL,
[modified_by] [int] NULL,
[modified_date] [datetime] NULL,
CONSTRAINT [PK_answer] PRIMARY KEY CLUSTERED
(
[sales_id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
when i run the below query i get error
[color=red]Conversion failed when converting the varchar value ' | | |0|0|0' to data type int.[/color]

-- alternative version
SELECT Product_ID
FROM (
SELECT f.Product_ID, agent_id, product_code
FROM #fact_sales f
WHERE (agent_id = 1 AND product_code = 1)
OR (agent_id = 2 AND product_code = 3)
OR (agent_id = 3 AND product_code = 2)
OR (agent_id = 4 AND product_code = 1)
GROUP BY f.Product_ID, agent_id, product_code
) d
GROUP BY Product_ID
HAVING COUNT(*) = 4

product_code is VARCHAR type...
What it means ' | | |0|0|0' ?
while converting '| | |0|0|0' to INT the error is causing
