Sorry, Eva, but it is not very clear what you want. Give a bit more sample
data.

One tricky question
I have a two tables - one is a source data and the second one is a new
data.
The two have same column headings.
The new data table can have new records or same records same as source
data,
but with some changes

For example

Record Table Heading
1 Source Department
1 New Department

I need to update the source data with the new records and update all the
information that has discrepancies in new data
I tried to set up a querry (miscrosoft querry) with no luck.
How to do it?
