Question

I need help refining the WHERE clause on a query for the table below:

Key   |   Name   |   Role   |   Location
111   |   Bob    | Manager  |  All Locations
222   |   Jim    | Manager  |  All Locations
333   |   Tim    | Sales    |  Washington
444   |   Roy    | Sales    |  New York
555   |   Lee    | Sales    |  All Locations
666   |   Gus    | Sales    |  All Locations
777   |   Joe    | Admin    |  All Locations
888   |   Jen    | Admin    |  New York

I need to exclude all the ‘All Locations’ records, but keep the ‘All Locations’ records where the Role is Manager. To get the desired result:

Key   |   Name   |   Role   |   Location
111   |   Bob    | Manager  |  All Locations
222   |   Jim    | Manager  |  All Locations
333   |   Tim    | Sales    |  Washington
444   |   Roy    | Sales    |  New York
888   |   Jen    | Admin    |  New York

I feel that the query below would exclude all the All Locations records, including the Manager ones.

SELECT * FROM Table
WHERE (Location <> 'All Locations' AND Role <> 'Manager')

Answer 1

You should use OR instead of AND

SELECT * FROM Table
WHERE (Location <> 'All Locations' OR Role = 'Manager')
