Question

I have a database of orders that looks roughly like this

   ORDER ID | AMOUNT | FIRSTNAME | LASTNAME
     1         50        JOHN       SMITH
     2         60        PAUL       JOHNSON
     3         20        FRANK      CAMERON
     5         80        JOHN       JOHNSON

I have a list of names that I need to pull their orders. For this example lets say “JOHN SMITH” and “PAUL JOHNSON”

I have tried a query like this

SELECT * FROM ORDERS WHERE FIRSTNAME IN ("JOHN", "PAUL") AND LASTNAME IN ("SMITH", "JOHNSON")

But obviously that didn’t work how I wanted as it included. I’m not sure how to go about it but I need to search something like

WHERE FIRSTNAME,LASTNAME IN ("JOHN","SMITH";"PAUL","JOHNSON")

OR

WHERE (FIRSTNAME,LASTNAME) IN {("JOHN","SMITH")("PAUL","JOHNSON")}

Obviously I know little about SQL so I’m getting stuck on syntax and terminology of what to search for?

Answer 1

You can separate the logic with an OR like this:

SELECT * FROM ORDERS
WHERE 
(FIRSTNAME = "JOHN" AND LASTNAME = "SMITH")
OR
(FIRSTNAME = "PAUL" AND LASTNAME = "JOHNSON")
