Hi,
Is the following postgres function correct?
CREATE OR REPLACE FUNCTION "MyFun"("IdArgs" INTEGER)
RETURNS SETOF "B" AS
$BODY$
CREATE VIEW "A" AS SELECT * FROM "B" WHERE "Id" = $1;
SELECT * FROM "B";
$BODY$
LANGUAGE 'sql' VOLATILE
COST 100;
ALTER FUNCTION "MyFun"(INTEGER) OWNER TO postgres;
Where “B” is a table in the DB schema.
Executing “select * from "MyFun"(1) “ throws the following error:
ERROR: there is no parameter $1
LINE 2: ...W "A” AS SELECT * FROM "B" WHERE "Id" = $1;
----------------
Where as the following function works fine:
CREATE OR REPLACE FUNCTION "MyFun"("IdArgs" INTEGER)
RETURNS SETOF "B" AS
$BODY$
CREATE VIEW "A" AS SELECT * FROM "B" WHERE "Id" = 1;
SELECT * FROM "B";
$BODY$
LANGUAGE 'sql' VOLATILE
COST 100;
ALTER FUNCTION "MyFun"(INTEGER) OWNER TO postgres;
Where “Id” is hardcoded within the function.
Is this expected? Please reply.
Regards,
DP
