I have 3 columns in a table, in which 2 columns have string separated by a '|' pipe. Both these columns values depend on each other.
For an example: I have data in the table like this :
ID product quantity
1 A|B|C 1|2|3
2 X|Y|Z 7|8|9
I would like to change it to something like this :
ID product quantity
1 A 1
1 B 2
1 C 3
2 X 7
2 Y 8
2 Z 9
As i am working with SSMS, i don't have any other choice except SQL. I try to use cross apply but i am not getting right result. For 1 row i receive 9 rows instead of getting 3. could anyone suggest me which method should i use?
Thank you in advance!! JACK
Test Data
CREATE TABLE #t (ID INT, product VARCHAR(100) , quantity VARCHAR(100) )
INSERT INTO #t VALUES
(1 ,'A|B|C' , '1|2|3'),
(2 ,'X|Y|Z' , '7|8|9');
Query
WITH Products AS (
SELECT ID
, Product_Split.a.value('.', 'VARCHAR(100)') Products
, ROW_NUMBER() OVER (PARTITION BY ID ORDER BY (SELECT NULL)) rn
FROM (
SELECT ID
,Cast ('<X>'
+ Replace(product, '|', '</X><X>')
+ '</X>' AS XML) AS Product_Data
FROM #t
) AS t
CROSS APPLY Product_Data.nodes ('/X') AS Product_Split(a)
),
Quantities AS (
SELECT ID
, Quantity_Split.a.value('.', 'VARCHAR(100)') Quantity
, ROW_NUMBER() OVER (PARTITION BY ID ORDER BY (SELECT NULL)) rn
FROM (
SELECT ID
,Cast ('<X>'
+ Replace(quantity, '|', '</X><X>')
+ '</X>' AS XML) AS Quantity_Data
FROM #t
) AS t
CROSS APPLY Quantity_Data.nodes ('/X') AS Quantity_Split(a)
)
SELECT t.ID
, P.Products
, Q.Quantity
FROM #t t
LEFT JOIN Products P ON t.ID = p.ID
LEFT JOIN Quantities Q ON Q.ID = t.ID
AND Q.rn = p.rn
