Eliminate duplicate data

Hi,
I want to eliminate duplicate entries from different tables into a single
new table and keep the reference from the original data.
Example:
Table1: toto, titi
Table2: toto, titi, tutu
Table3: tutu, tata
the new table will contain:
NewTable: toto, titi, tutu, tata
and i want to keep a reference that allows to retrieve that toto comes from
Table1 and Table2
tutu comes from Table2 and Table3...
if someone can help me it would be great.
Thanks.
Beter than a single new table, You can make a View
UNION will eliminate duplicate data.
SELECT Field FROM Table1
UNION
SELECT Field FROM Table2
UNION
SELECT Field FROM Table3
To know where 'toto' come from:
SELECT TableName FROM
(
SELECT 'Table1' AS TableName, Field FROM Table1
UNION
SELECT 'Table2' AS TableName, Field FROM Table2
UNION
SELECT 'Table3' AS TableName, Field FROM Table3
) Tmp
WHERE Field='toto'

Effects of changing a table name

If I rename a table on my SQL Server 2005 database say from Carriers to
Partners, will it update the stored procedures that reference the old table
name "carriers" to the new "partners" name? I am talking about using the
rename function in the rename function in the micosoft SQL Server managment
studio program. Or will I have to edit my 1,351 stored procedures manually?

No, SQL Server is not going to go and edit your code for you. It would be
hard enough to find all the places it is referenced in vanilla T-SQL (and
this would rely on a correct sysdepends, rather than deferred name
resolution), what about all the places where the table name could be
referenced dynamically (e.g. EXEC('SELECT * INTO t1 FROM Carriers', or
EXEC('SELECT * INTO t1 FROM Car'+'riers'), or EXEC('SELECT * FROM
'+@.TableName))? Even if you took your procedure code offline and did a
grep/replace, you're still not guaranteed to find every single location.

An alternative would be to create a synonym.
