Hi ,


create a global temporary table mytable as follows in Oracle:

create global temporary table mytable (

   column definitions

) on commit preserve rows;

However, I also want to bulk insert hundreds of rows without writing a SQL insert statement hundreds of time.

select * from mysourcePool;  -- hundreds of rows to be used in bulk insert data

How do I combine both operations?

insert into mytable (a,b,c,d)  select w,x,y,z from mysourcepool.


replace a,b,c,d,w,x,y,z  with your real columns, expand as needed

You don't need hundreds of "insert...select ...from..." statements to insert hundreds of rows to either a global temporary table or a standard Oracle table.

You simply add "where" clause conditions to the "select ... from..." part of the statement to include whatever rows should be included.   These will all be inserted in one step with no "bulk collect" needed.  This is faster and more efficient that using a PL\SQL procedure that includes a cursor and "bulk collect".
