Hello all,

I have the following.   I have a table called Customer that has the following data for example:

Customer
CustId        CustDate       CustOrdAmount      CustGrpAmount
1                 9/2/2014      1000.00                  900.00
1                 10/1/2014      800.00                  800.00
1                 11/2/2014      900.00                  100.00
2                  8/4/2014       990.00                  990.00
2                  9/5/2014       700.00                  800.00
I then have another temp table I will create that will have the following:

#TempCustomer
CustId         CustDate      CustOrdAmount      CustGrpAmount
1                 11/29/2014     800.00                     500.00
2                 10/30/2014     700.00                     800.00

What I need to do is check based on the CustId if the temp table CustOrdAmount delta is different OR the CustGrpAmount is different than the Max(CustDate) record in Customer for that CustId then Insert a new record into the Customer Table otherwise ignore the insert from the Temp table to the Customer table for that CustId.

So in this case above I would be comparing the 3rd record in Customer table CustId = 1 to the TempTable CustId = 1 and inserting a record into the Customer table.  For CustId = 2 I would be ignoring that insert they are the same both columns.
