Question

How Do I set multiple AND conditions?
ex.

SELECT *
FROM CONFIRMED
WHERE NOT EXISTS 
( 
    SELECT * 
    FROM Import_Orders
    WHERE Import_Orders.Customer = CONFIRMED.Customer
        AND Import_Orders.Reference = CONFIRMED.Reference
        AND Import_Orders.[Index] = CONFIRMED.[Index]  
        AND Import_Orders.QuantityToDeliver = CONFIRMED.QuantityToDeliver  
        AND Import_Orders.DateToDeliver = CONFIRMED.DateToDeliver  

);

I know this works on my tables with one WHERE & AND condition but not with several.

I Need a result of two tables where the above conditions do not match. I do not have identical keys in the two tables. Now with this code I get all the results that are in table CONFIRMED.

Answer 1

I am guessing that you have an ID on Import_Orders, if not use any field name that is turning up empty on the query. You would be better using field names rather than *. I have added an example for Import_Orders.

SELECT CONFIRMED.*, Import_Orders.ID, Import_Orders.Customer
FROM CONFIRMED 
LEFT JOIN Import_Orders
ON Import_Orders.Customer = CONFIRMED.Customer
AND Import_Orders.Reference = CONFIRMED.Reference
AND Import_Orders.[Index] = CONFIRMED.[Index]  
AND Import_Orders.QuantityToDeliver = CONFIRMED.QuantityToDeliver  
AND Import_Orders.DateToDeliver = CONFIRMED.DateToDeliver  
WHERE Import_Orders.ID Is Null
