In this chapter, you learn how those types let you reference and manipulate collections of data as whole objects.You also learn how the datatype is an ordered group of elements, all of the same type.And it does precisely that through its implementation of the datatype, such as a number or string.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.

To support these techniques in database applications, PL/SQL provides the datatypes , which allow you to declare index-by tables, nested tables and variable-size arrays.PL/SQL offers these collection types: Although collections can have only one dimension, you can model multi-dimensional arrays by creating collections whose elements are also collections.To use collections in an application, you define one or more PL/SQL types, then define variables of those types.For full explanations of both of these answers, visit plsqlchallenge.com, register or log in, and click the Closed/Taken tab in Play a Quiz.The Oracle PL/SQL language was designed to be a portable, high-performance transaction processing language that is tightly integrated with the SQL language.This article explores how you declare records, populate them with rows from a table, and even insert or change an entire row in a table by using a record.
