Sorry, in that case. Shot the DBA, DB developer or even Linda. ;-)

If Linda can access table_a then there is either:

* A table or view TABLE_A in Linda's schema or a PRIVATE synonym TABLE_A
pointing to something else, either in Linda's schema or another schema

AND/OR

* There is a PUBLIC synonym TABLE_A pointing to a table or view


If Linda shouldn't be aware what she access behind the scene, then shot
the DBA or DB developer to make sure that Linda access the right thing.
Otherwise, make sure that Linda uses a full qualified name including the
schema name.

In DBMS with schema support, it's always a GOOD practice to full qualify
a object name, just in case one isn't sure which object he/she access.
