It’s rare, in fact, that the data with which you are working is just a single value, so records and other composite datatypes are likely to figure prominently in your PL/SQL programs.

An elegant and simple way to do this in PL/SQL is to take advantage of the cursor FOR loop (which I discussed in part 2 of this PL/SQL 101 series).

PL/SQL offers special syntax in both the INSERT and UPDATE statements so that you can easily use records to perform those data manipulation language (DML) operations as well.

The most common form of an INSERT statement is where column_list is the list of columns that will be populated on insert and expression_list is the list of expressions that will be assigned to their respective columns.

Because only one exception can be raised at a time in a session, it doesn’t make any sense to allow you to check for two (or more) exceptions in a single handler.

This way, when and if the SELECT list of the cursor changes, the number and type of fields in the record will change accordingly and everything will stay in sync.
