Hello,
I need to know why can't I do it?
CREATE OR REPLACE FUNCTION lost_hours_temp(date)
RETURNS text AS
$BODY$
DECLARE
START_DATE date;
END_DATE date;
QUERY text;
BEGIN
START_DATE := $1;
END_DATE := START_DATE - interval '3 year';
The last line (END_DATE := START_DATE - interval '3 year';) generate the
following error:
ERROR: operator is not unique: "unknown" / "unknown"
SQL state: 42725
Hint: Could not choose a best candidate operator. You may need to add
explicit type casts.
Context: PL/pgSQL function "lost_hours_temp" line 10 at assignment
How can I solve it?
Thanks
Try adding explicit casts with the "::" operator.
