PLSQL stands for Procedural Language extensions to the Structured Query Language (SQL). It is a powerful language for both querying and updating data in relational databases.
PLSQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types Cheap Jerseys China , and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PLSQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PLSQL units such as procedures, functions, packages, types, and triggers Cheap Jerseys , which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces.
The main feature of SQL (non procedural) is also a drawback of SQL. One can use control statements like decision making, iterative control if only SQL is to be used. PLSQL is basically a procedural language, which provides functionality of decision making, iteration and many more features like other procedural programming languages. A PLSQL program unit is one of the following: PLSQL anonymous block, procedure Wholesale Football Jerseys , function, package specification, package body, trigger, type specification Wholesale Nike NFL Jerseys , type body, library. Program units are the PLSQL source code that is compiled, developed and ultimately executed on the database.
PLSQL anonymous block
The basic unit of a PLSQL source program is the block, which groups together related declarations and statements. A PLSQL block is defined by the keywords DECLARE, BEGIN Wholesale NFL Jerseys , EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label.
Function
The purpose of a PLSQL function is generally to compute and return a single value. This returned value may be a single scalar value (such as a num ber, date or character string) or a single collection (such as a nested table or varray). User-defined functions supplement the built-in functions provided by Oracle Corporation.
Procedures
Procedures resemble functions in that they are named program units that can be invoked repeatedly. The primary difference is that functions can be used in a SQL statement whereas procedures cannot. Another difference is that the procedure can return multiple values whereas a function should only return a single value. The procedure begins with a mandatory heading part to hold the procedure name and optionally the procedure parameter list. Next come the declarative Wholesale Jerseys Free Shipping , executable and exception-handling parts, as in the PLSQL Anonymous Block.
A procedure may also be created in a PLSQL package - this is called a Package Procedure. A procedure created in a PLSQL anonymous block is called a nested procedure. The standalone or package procedures, stored in the database, are referred to as "stored procedures".
Procedures can have three types of parameters: IN, OUT and IN OUT.
1. An IN parameter is used as input only. An IN parameter is passed by reference Wholesale Jerseys From China , though it can be changed by the inactive program.
2. An OUT parameter is initially NULL. The program assigns the parameter a value and that value is returned to the calling program.
3. An IN OUT parameter may or may not have an initial value. That initial value may or may not be modified by the called program. Any changes made to the parameter are returned to the calling program by default by copying but - with the NOCOPY hint - may be passed by reference.
PLSQL also supports external procedures via the Oracle database's standard process
Packages
Packages are groups of conceptually linked functions, procedures, variables, PLSQL table and record TYPE statements, constants Wholesale Jerseys , cursors etc. The use of packages promotes re-use of code. Packages are composed of .
