@dinesh.

Use full outer join for tables 1 and table 2. You should have at least one column common in between these two tables.

Sample Script

Select A.cola, A.Colb, A.colc, B.colb, B.colc
FROM Table1 A Full Outer Join Table2 B on A.cola = B.cola

Refer to this article for more details on Joins,

One of the most important advantages of MERGE statement is all the data is read and processed only once. (Read More Here) [...]

Hi Pinal Dave,
Thanks for most of the very useful articles you write..Just something that still puzzles me and you might have the answer.
To be it seems 2008 MERGE statement and CDC perform the same function during the ETL process that is best used in SCD situations.
What i do see is CDC tracking and capturing data into a Different Table..
My question is do they perform different functions.

Thanks

Nice article…I have one doubt…

Do we need to select StudentName in the Source Table like
“SELECT StudentID,StudentName FROM StudentDetails”, which is never used in the Join?
