Question

How can I write a MySQL query that returns true/false (1/0 actually) based upon the value of a column.

In my instance I want to return “hasDate” for a date time col, let’s call it myDateTime

if myDateTime has a value of 000-00-00 00:00:00 I want to return hasDate of 0 (false)

If myDateTime has any other value I want to return hasDate of 1 (true)

Thanks for your assistance.

Answer 1

Use a IF statement

SELECT IF(myDateTime = '0000-00-00 00:00:00',0,1) AS hasDate FROM myTable

But the best idea would be to change your data structure to avoid doing that.
