Subject [jira] Commented: (DERBY-3946) Provide support for using the Derby parser to generate Abstract Syntax Trees
Date Wed, 31 Mar 2010 22:02:27 GMT

Derby Ciu commented on DERBY-3946:
----------------------------------

Hi Rick,

I have two questions for you. 

1) I am trying to analyze which function call is responsible for printing the parse tree.


 2) What is the exact point  in the code when a " * " gets replaced with the column names
in a query like "Select * from tablename"  where tablename is a table with different column
names clm1,clm2,clm3 etc.

If you could please help me with these asap.

Thank you,
Ciu
