Mike Matrigali updated DERBY-791:

    Component: SQL

> -------------------------------------------------------------------------------
>
>          Key: DERBY-791
>          URL: http://issues.apache.org/jira/browse/DERBY-791
>      Project: Derby
>         Type: Improvement
>   Components: SQL
>     Reporter: Rick Hillegas

>
> Currently you can print Abstract Syntax Trees to derby.log by setting the DumpParseTree
tracepoint at server startup. E.g.:
> java -cp $CLASSPATH -Dderby.debug.true=DumpParseTree -Dderby.stream.error.logSeverityLevel=0
org.apache.derby.tools.ij  z.sql
> This can be a useful debugging tool. However, it only works on debug servers built with
the following flags:
> sanity=true
> debug=true
> We should provide some mechanism for printing these trees in production (non-debug) servers.
