Subject: 'retrieve into' in a rule?
Date: Mon, 9 May 1994 10:59:52 -0400 (EDT)
Message-ID: <9405091459.aa05728@s.s.ms.uky.edu> (raw)
I am running with Postgres 4.2.
When I give a command to the monitor like
"retrieve into temp (emp.name) where emp.age = 40\g"
it works fine and creates the class temp with the info,
BUT if I put the same kind of command into a _rule_,
"define rule r5 is on
retrieve to emp.age where current.age ISNULL
do [retrieve into x (emp.all) where emp.dept= current.dept ] \g"
the rule is defined alright,
but when I actually try to retrieve from emp,
"retrieve (emp.all) \g"
I get a message that "type x already defined"
and no tuples are retrieved.
Suggestions?
