Question

I’m not sure if I can do this in one query but I would like to.

I need all records like this:

SELECT a.field_1, a.field_2, b.field_3, b.field_4
  FROM tbl_a AS a, tbl_b AS b
 WHERE a.field_1 = b.field_3

And I would like to also exclude these records that fall into this condition:

IF a.field_1 IN (1,2,3,4) 
AND a.field_date < NOW()

UPDATE: (sorry for the confusion)

• So if field_1 equals 1,2,3 or 4 and has a date timestamp that is today I need to display the record (add to results)
• And if field_1 equals 1,2,3 or 4 and has a date timestamp that is less than today (remove it from the results).

Any ideas to get both results into one query

Notes (if this makes a difference):

• field_a can have a value a-z, 1-99 (two characters only)

Answer 1

Something like this?

SELECT a.field_1, a.field_2, b.field_3, b.field_4
FROM tbl_a AS a, tbl_b AS b
WHERE a.field_1 = b.field_3
AND (
CASE WHEN a.field_1 IN (1,2,3,4) THEN
      CASE WHEN A.FIELD_DATE = NOW() THEN 1 ELSE 0
      END
ELSE 1
END) = 1
