oracle diff: how to compare two tables?

Question

Suppose I have two tables, t1 and t2 which are identical in layout but which may contain different data.

What\'s the best way to diff these two tables?

Answer 1

You can use a tool like AQT to create diffs between tables.

Another approach would be to dump the tables to a text file and use a diff tool like WinMerge. With this approach, you can use complex SQL to turn the tables into the same layout, first.
