Simple question - but my brain is not working:
This is my table
Column | Type |
Modifiers
-----------+------------------------+-----------------------------------------------------------------
id | integer | not null default
nextval('emr_clinicschedule_id_seq'::regclass)
clinic_id | integer | not null
date | date |
day | smallint |
status | boolean | not null
open | time without time zone |
close | time without time zone |
reason | character varying(64) |
active | boolean | not null
I want to find any value:
SELECT id FROM schedule WHERE clinic_id = '%s' AND date = '%s'
But I want to make sure the clinic exist first then find if the date
exist 2nd.
How do I do that?
Thanks in advance,
J
