I think you need to have a conversation with your boss that goes
something like this:
"Hey boss, you can ask me to do something, or you can tell me how to do
it....but you can't do both!" ;-)
My point is, he wants an answer to a question, that being "Is the data
in these tables in these two databases the same or not?" As long as the
method is valid, what business does he have dictating what methods
should not be used?
I know, there are impossible bosses all over the place, but, really, he
needs to let you do your job.
Ok, here's an actual attempt to answer your question:
Spool contents of table to a file, compute md5 sum.
Spool contents of other table to file, compute md5 sum.
Compare md5 sums.
Hope that helps,
-Mark

I think my boss wants programmatic solution here, something like
summarizing data in certain columns and comparing values.

Well can you:
Create table cpytable1 as select * from table1;
Export cpytable1;
Import cpytable1 into other database.
Then use minus to compare the two tables?

Thanks Luis and Guang.
I personally like spool&diff option but my boss doesn't, so
can't use that.
minus option is not an option because tables are in different
databases, no link.

If you only need to compare the contents , you can use
select * from table1 minus select * from table2;
select * from table2 minus select * from table1;

Hi list,
I need to quckly compare tables in 2 schemas to verify
contents are identical.
Counting blocks/rows, using tools to compare schemas is
not possible.
Something similar to checksum mechanism is requested.
Any ideas ?
