Question

If is_closed is returned as true from a query, how do I tell the query to set closing_time to closed, instead of displaying what is really in the row… such as 23:00:00 ?

I tried

AND IF(is_closed = 1, 1, 0) closing_time = 'closed'

but that resulted in

You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ‘closing_time = ‘closed’ GROUP BY venues.VENUE_NAME’ at line 27

Thanks!

edit closing_time is a date field.

Answer 1

In your field list add a conditional statement:

SELECT 
  < some column(s) here >, 
  CASE WHEN is_closed = 1 
       THEN 'closed' 
       ELSE closing_time END AS CLOSING_TIME_OR_CLOSED
...

In contrast to the IF statement, the CASE statement is ANSI SQL meaning you can run your query on any RDBMS which implements the ANSI standard.
