append rows from one table to another table

I have two tables. TBL_SOURCE and TBL_DEST.
TBL_SOURCE has columns col1, col2, and col3.
TBL_DEST has columns col2, and col3.
col2, and col3 have the same names and definition in both tables.

What is the syntax for Appending 12 rows from TBL_SOURCE to TBL_DEST ?

Thanks,

Sample data and expected results would help a lot but maybe something like this:
insert into tbl_dest(
select col2,col3 from tbl_source
minus
select col2,col3 from tbl_dest
);

The append does not need to be executed as a single select statement.
A procedure could be used.

A plan similar to this may work:
 Build a cursor by selecting rows from the source table.
 SELECT bla, bla from source
 Count the number of rows selected
     intRowCount NUMBER;
     intRowCount   := SELECT bla, bla from source

Loop through the cursor until inRowCount is reached
       Insert into the destination table

Hopefully a bulk insert statement would work.

I cannot try these ideas until Monday.

Will it work, maybe, but why bother?

Why create an in-memory table just to loop through the rows when the cursor above does it all for you?

Just because you 'can' do something doesn't mean it is a good idea...
