Question

In most sql databases I have seen you can do something like: 

SELECT ABS(-2.4)

and I get back 2.4. Notice there is no FROM clause.

When I try to do this in OpenEdge via Squirrel and the JDBC driver I get a syntax error. Is there a way to run SELECT statements like this (sans FROM clause) via JDBC?

Was it helpful?

Solution

Single row/column Dual equivalent; SYSPROGRESS.SYSCALCTABLE
