I'm not sure what you mean, but have you tried the INFORMATION_SCHEMA.COLUMNS view?

Yes , I have tried using the basic names

SELECT COLUMN_NAME, TABLE_NAME
FROM INFORMATION_SCHEMA.COLUMNS

but i am receiving invalid Table name or View .

The main Problem over here is that " The Tables are not in the Direct Database , they are inside to the Individual Users (Roles) who are in that Database

ummm....tables do not reside inside of a user or a role. They exist in the database, access to those tables is handled by the permissions granted to users and/or roles.

Do you get an error when you run this?

SELECT COLUMN_NAME, TABLE_NAME

FROM INFORMATION_SCHEMA.COLUMNS

i think he's very oracle oriented.

I tend to use the Oracle or SQL related views, instead of the information_schema stuff;

so for example, in oracle, i'd query user_tab_cols; in SQL, i'd query sys.columns directly

--ORACLE
select * from user_tab_cols where column_name='ACTTBLKEY';
--SQL-
SELECT OBJECT_NAME(object_id) As TABLE_NAME,* from sys.columns WHERE name = 'ACTTBLKEY';
