问题
I want to create a variable based on the table "query" (l_query query%ROWTYPE), but I got this message: invalid type name "query%ROWTYPE"
I also tried to use the fully qualified table name l_query dbname.public.query%ROWTYPE, but it didn't help me ether.
CREATE OR REPLACE FUNCTION somefunc()
RETURNS int AS $$
DECLARE
l_res dbname.public.query%ROWTYPE;
BEGIN
return 1;
END;
$$ LANGUAGE plpgsql;
PS:I do have the table query. I checked it a couple of times. I have this error only on the production server. Locally, I ran it with no problems
version
PostgreSQL 9.2.4 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit
回答1:
A non-quoted reference to query probably confuses the plpgsql parser since QUERY is also a keyword used in the RETURN QUERY ... construct.
The generic solution is to add double quotes around the problematic identifier:
DECLARE l_res "query"%ROWTYPE;
As for your fully qualified variant, there's another problem with it: only a schema name may prefix a table name, not a database name plus schema name.
These declarations should also work:
DECLARE l_res public."query"%ROWTYPE;
or
DECLARE l_res "public"."query"%ROWTYPE;
