Status: Verified

FACT(s) (Environment):

OpenEdge 10.0B
OpenEdge 10.1A

SYMPTOM(s):

Poor performance rendering application unusable

Executing SQL-92 join query

Sometimes the result set is never returned

The machine hangs since all the system CPU is used

Using the "{no reorder}" option improves the performance significantly.

CAUSE:

Bug# 20060301-023

FIX:

Upgrade to OpenEdge 10.0B05 or later

Upgrade to OpenEdge 10.1A01 or later.

If upgrading is not possible, adding the {no reorder} option in the query at the end of the FROM allows to improve performance.
