Hi,
Looking for the correct syntax for an UPDATE LEFT JOIN query in PostgreSQL.
The equivalent MySQL query is :
UPDATE
Foo f LEFT JOIN Goo g on f.Foo_ID = g.Goo_ID
SET
f.Foo_ID = g.Goo_ID
WHERE
f.Foo_ID IS NOT NULL;
When I try to run this in Postgres, i get the following error:
ERROR: syntax error at or near "LEFT"
Is it possible to have UPDATE JOIN queries in PostgreSQL?
Thanks.
sorry the last message have a error
try whit this
update foo set Foo_ID = goo.Goo_ID from goo where goo.Goo_id = foo.Foo_id and foo_ID IS NOT NULL;
