Traditionally, developers used operators such as LIKE, REPLACE, and SUBSTRING in their search expressions. However, these expressions forced you to write lengthy SQL and PL/SQL code when performing complex searches. Oracle Database 11g lets you perform complex searches and string manipulations easily with regular expressions.

A regular expression searches for patterns in character strings. The character string has to be one of CHAR, VARCHAR2, NCHAR, or NVARCHAR2, and the regular expression function can be one of the following: REGEXP_LIKE REGEXP_REPLACE REGEXP_INSTRING REGEXP_SUBSTRING The REGEXP_LIKE function evaluates strings using a specified set of characters. The regular expression function searches for a pattern in a string, which is specified with the SOURCE_STRING parameter in the function. The PATTERN variable represents the actual regular expression, which is the pattern to search for. A regular expression is usually a text literal; it can be one of CHAR, VARCHAR2, NCHAR, or NVARCHAR2, and it can be a maximum of 512 bytes long. You can also specify an optional match parameter to modify the matching behavior. For example, a value of i specifies case-insensitive matching, while c specifies case-sensitive matching. Here is the syntax of the REGEXP_LIKE function: REGEXP_LIKE(source_string, pattern [,match_parameter]) If you want to carry out string-manipulation tasks, you can use the REGEXP_INSTR, REGEXP_ REPLACE, or REGEXP_SUBSTR built-in functions. These are really extensions of the normal SQL INSTR, REPLACE, and SUBSTR functions. Regular expression features use characters like the period (.), asterisk (*), caret (^), and dollar sign ($), which are common in UNIX and Perl programming. The caret character (^), for example, tells Oracle that the characters following it should be at the beginning of the line. Similarly, the $ character indicates that a character or a set of characters must be at the very end of the line. Here s an example using the REGEXP_LIKE function that picks up all names with consecutive vowels: SQL> SELECT last_name FROM employees WHERE REGEXP_LIKE (last_name, '([aeiou])\1', 'i'); LAST_NAME ----------Freedman Greenberg Khoo Gee Lee . . .

Abstract Data Types
This section briefly reviews the important Oracle features that facilitate object-oriented programming. Abstract types, also called object types, are at the heart of Oracle s object-oriented programming. Unlike a normal data type, an abstract data type contains a data structure along with the functions and procedures needed to manipulate the data; thus, data and behavior are coupled. Object types are like other schema objects, and they consist of a name, attributes, and methods. Object types are similar to the concept of classes in C++ and Java. Oracle support for object-oriented features, such as types, makes it feasible to implement object-oriented features, such as encapsulation and abstraction, while modeling complex real-life objects and processes. Oracle also supports single inheritance of user-defined SQL types.
The CREATE TYPE Command
Object types are created by users and stored in the database like Oracle data types such as VARCHAR2, for example. The CREATE TYPE command lets you create an abstract template that corresponds to a real-world object. Here s an example: SQL> CREATE TYPE person AS object 2 (name varchar2(30), 3 phone varchar2(20)); Type created. SQL>
Object Tables
Object tables contain objects such as the person type that was created in the previous section. Here s an example: SQL> CREATE TABLE person_table OF person; Table created. SQL> Here s the interesting part. The person_table table doesn t contain single-value columns like a regular Oracle table its columns are types, which can hold multiple values. You can use object
