New Post: Comparing Oracle Table Row Values

Hi everybody, I'm a new programmer.

My first project is to create a webpage to show the discrepancies of Store Transactions Report.

Database :Oracle 9i 

Programming Language:C#

Two Tables that needed to be match :

Table A (Column Names: Amount,Date,Time,Store_Number)

Table B (Column names are the same with Table A)

Procedure : Select Table A and Table B, find the unmatched Data and insert in Table C (same column names with Table A& B).

How do I match the values of each row using C# codes?
