I have 2 tables INVENTORY and PRODUCTS and I want to select some columns of the INVENTORY and one from the PRODUCTS. I wrote:
SELECT INVENTORY.product, INVENTORY.version, PRODUCTS.customer
FROM INVENTORY
INNER JOIN PRODUCTS ON
INVENTORY.product = PRODUCTS.product AND INVENTORY.version= PRODUCTS.version
and I get multiple times the same records.. How I fix it?
Simple distinct or group by:
SELECT DISTINCT INVENTORY.product, INVENTORY.version, PRODUCTS.customer
FROM INVENTORY
INNER JOIN PRODUCTS ON
INVENTORY.product = PRODUCTS.product AND INVENTORY.version= PRODUCTS.version
Or :
SELECT INVENTORY.product, INVENTORY.version, PRODUCTS.customer
FROM INVENTORY
INNER JOIN PRODUCTS ON
INVENTORY.product = PRODUCTS.product AND INVENTORY.version= PRODUCTS.version
GROUP BY INVENTORY.product, INVENTORY.version, PRODUCTS.customer
