garpinc created OPENJPA-2265:
--------------------------------
Summary: An unnecessary select statement appears to be occurring
on primary key table
Key: OPENJPA-2265
URL: https://issues.apache.org/jira/browse/OPENJPA-2265
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 2.2.0
Reporter: garpinc
This issue pertains to
http://openjpa.208410.n2.nabble.com/Can-someone-explain-this-OpenJPA-trace-td7580862.html
Basically I'm seeing an unnecessary select statement of the form:
1487 test TRACE [main] openjpa.jdbc.SQL - <t 1920940938, conn 488448102>
executing prepstmnt 163450945 SELECT t0.otherField1, t0.uniqueField1 FROM
KeyClass t0 WHERE t0.pk = ? [params=(long) 0]
My application does millions of these so performance is suffering. I'll be
attaching a test case to illustrate. testselect0.zip
