    How do I find the number of rows processed inside a pl/sql block? I want to commit the transaction only if the number of rows deleted = rows inserted into another table.

    Thanks in advance.

    Hi,
    This is Rohit ,OCP from India.
    Inside a pl/sql u can find out the number of rows processed by rowcount attribute of cursor.

    eg.
    declare
    x number;
    begin
    insert into emp_dup
    select * from emp;
    select count(*) into x from emp_dup;
    if sql%rowcount=x then
    delete from emp;
    end if;
    end;

    sql%rowcount attribute of cursor tells u how many rows have been processed.

    If any doubts please be free to write to me at
