Oracle updating records within same cursor

Cursor FOR Loops and Implicitly Declared Records Suppose I want to write a program to display the last names of all employees.

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).

Collections, PL/SQL’s implementation of arraylike structures, are used in some of the most important performance-related PL/SQL features, including FORALL and BULK COLLECT.

records because they are similar in structure to a record defined on a table with %ROWTYPE but are restricted in their usage.

If I want to provide a value for each column in a table that has, say, 500 columns, writing and managing that code can become quite tedious.

Inserting with a record comes in very handy in such a scenario.

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.
