sql zero leading in comparing 2 record set - sql

Question

I have a problem compare 2 set of data with and without leading zero.
In the Inventory_NBP, there is as 000000000000909120.
However, in PDM_Analysis, there exist only 909120 without the leading zero.
The current query below failed to retrieve any 000000000000909120 or 909120 as the "IN" condition is not met.
How do i modify the query below to fulfill my requirement?
sel * FROM Inventory_NBP.v_dmnd_rsrv_dpnd_rqr_mrp
WHERE plnt_id ='WA01'
and mtrl_id in('G29329-001', '000000000000909120', '13-0006-001')
and
(mtrl_id, plnt_id)
IN
( SELECT itm_cd, sap_plnt_cd
FROM PDM_Analysis.v_itm_plnt_extn
)

Answer 1

Do casting. This may solve your problem. Please check.
SELECT * FROM Inventory_NBP.v_dmnd_rsrv_dpnd_rqr_mrp
WHERE plnt_id ='WA01'
and mtrl_id in('G29329-001',CAST(CAST('000000000000909120' AS INT) AS VARCHAR(10)), '13-0006-001')
and
(mtrl_id, plnt_id)
IN
( SELECT itm_cd, sap_plnt_cd
FROM PDM_Analysis.v_itm_plnt_extn
)

Here's an example of how to match values regardless of leading zeros by padding (SQL Server 2008 syntax):
WITH T1
AS
(
SELECT *
FROM (
VALUES ('000000000000909120'),
('00000000099'),
('000000055'),
('22'),
('152')
) AS T (data_col)
),
T2
AS
(
SELECT *
FROM (
VALUES ('909120'),
('99'),
('00055'),
('0000000022'),
('152')
) AS T (data_col)
)
SELECT *
FROM T1 INNER JOIN T2
ON T1.data_col
= REPLICATE('0', LEN(T1.data_col) - LEN(T2.data_col))
+ T2.data_col
UNION
SELECT *
FROM T1 INNER JOIN T2
ON T2.data_col
= REPLICATE('0', LEN(T2.data_col) - LEN(T1.data_col))
+ T1.data_col;
