Need some help with UPDATE syntax. I am attempting to do something like this:
WITH default_facility AS (
SELECT facility_id,
inkjetorlabel
FROM engagement_facility_defs
WHERE engagement_facility_def_id = 8
)
UPDATE engagement_facilities SET (
facility_id,
inkjetorlabel
)
= ( default_facility.* )
FROM default_facility
WHERE engagement_facilities.engagement_id =3
Postgres errors out on the SET() saying "number of columns does not match
number of values". Also tried default_facility.* without the parenthesis but
it does not like that syntax. This example is a bit simplified, in reality
there are 90 columns in both lists.
Is this syntax not possible? I have rewritten it to this form which works, but
I rather like the CTE syntax instead.
UPDATE engagement_facilities SET (
facility_id,
inkjetorlabel
)
= ( df.facility_id, df.inkjetorlabel )
FROM engagement_facility_defs df
WHERE engagement_facility_def_id = 8
AND engagement_facilities.engagement_id =3
