Thread: Trigger problem
Hi friends! I'm working in a trigger and I need to put the result of a query into a variable. That's very easy- apparently! The query has a aggregate function like this: select sum(field) into variable ... and I'm sure that field and variable are int4 type. So, when I run this trigger there is a mistake: ''there is no operator '=$' for types 'int4' and 'int4' you will either have to retype this query using an explicit cast, or you will have to define the operator using CREATE OPERATOR'' what's meaning this? and how can I assign the result of aggregate function into a variable? (My system is 6.5.3)

Update to 7.0.3. It might work to add spaces around the '=' signs in your trigger function, but an update would be a good idea anyway. regards, tom lane
