I need a query to get list of product_id for the below conditions
I referred a stock question ( MySQL Multiple Where Clause ) and tried but not able to get the actual output.
Use OR
in your WHERE
clause and also use brackets to split each condition.
SELECT id, product_id, attribute_id, value
FROM shoppingcart
WHERE (attribute_id = 1 AND value IN ('B', 'C'))
OR (attribute_id = 2 AND value = 150)
OR (attribute_id = 4 AND value = 'NO')
Try this:
SELECT product_id FROM table_name WHERE
(attribute_id = 1 AND (
(value LIKE 'B,%' OR value LIKE '%,B' OR value LIKE '%,B,%' OR value LIKE 'B')
OR
(value LIKE 'C,%' OR value LIKE '%,C' OR value LIKE '%,C,%' OR value LIKE 'C')
)
)
OR
(attribute_id = 2 AND value = '150')
OR
(attribute_id = 3 AND value = 'NO')
