There is an alternative method of handling cursors. It is called the cursor FOR loop because of the simplified syntax that is used. When using the cursor FOR loop, the process of opening, fetching, and closing is handled implicitly. This makes the blocks much simpler to code and easier to maintain.
The cursor FOR loop specifies a sequence of statements to be repeated once for each row returned by the cursor. Use the cursor FOR loop if you need to FETCH and PROCESS each and every record from a cursor.
▪ FOR EXAMPLE
Assume the existence of a table called log with one column.
create table table_log ...
