Sorry but I don't understand. Either the LIMIT and OFFSET are to be definitely CONSTANT or not. In the SQL function body the LIMIT and the OFFSET *are definitely not* CONSTANT. And the planner can do its job at best as usual. As Sam says I should be able to "put an IMMUTABLE expression into a LIMIT or OFFSET". And under some circumstances (SQL function body) it's true even with VARIABLE expressions like function call arguments. In my opinion I would say it's more a problem with the syntax checker that with the planner ("semantics" in my lingo). But I could be wrong. -- Reg me Please ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
