Hi all,

I have got a confusion.

    I am using Crystal Report X, Oracle Database, JDBC drivers.

I have a schema on which I have applied a trigger to restrict any Alter command.
   
    When I make connection in crystal reports, I can make connection, but I can't select and include table(s) in database expert. An error occurs:

Trigger throws that error
ORA-20000: Cannot Alter Database, Consult your DBA

When I disables that trigger the tables would includes without error.

I am surprised that, Does Crystal Report Alter Table(s) on the time of including tables to make query???
If Yes then which are those table(s)???
