Thanks for the email and glad that you like my web page.

Also, welcome to the world of DBA's! I am sure that you'll get more
comfortable as time goes by.

As for your question, it is hard to say exactly why your script does not
work anymore. First, see if the table exists:


If it does not exists as a table, then maybe as a synonym:


Maybe a view?:


If the table/synonym/view exists but under a different user, make sure
that you have appropriate privilieges on that object. For example, if the
table is owned by SAM and your GREGG user does not have the ability to
select from the table, connect as SAM and issue:

GRANT SELECT ON enter_name_here TO GREGG;

Your script will hopefully work now.
