How to specify OR condition in SQL query?

Question

SQL

Good afternoon, I'm doing a lab, there is a request to get data from the call table:
$query = "SELECT * FROM zvonki WHERE res1='0' AND date < '$data_pl' AND id_sp='67' ORDER BY 'id' ASC LIMIT 1 ";
Now the request includes calls with conditions:
res1=0
date<$data_pl
id_sp=67 The
question is how to request calls with one request:
res1=0
date<$data_pl
id_sp=67 or 68 I'm stupid
, I can't figure it out.

Answer 1

SELECT * FROM zvonki WHERE res1='0' AND date < '$data_pl' AND id_sp IN (67,68) ORDER BY 'id' ASC LIMIT 1
