Of all the objects in a database, to my mind, the table is the most popular. Tables can be created manually and automatically. Manually creating a table is by creating table structure through filling of the required entries in the table design interface of the database. The automatic initiation can receive on any of the following forms-
Use of command parentage to enter SQL declaration subsequent to MySQL command lineage.
Running SQL table foundation confirmation in the database.
Use of scripts to control SQL statements at tolerate know-times, that is, in the back the application is supervision. Table is created energetically this quirk.
All the automatic means touch the use of Structured Query Language (SQL). Structured Query Language (SQL) is a database language that allows a fan to -
Create the database and relational structure.
Perform basic data meting out tasks, such as the insertion, modification, and taking away of data from relatives.
Perform both easy and puzzling queries to transform the raw data into opinion.
Structured Query Language (SQL) has two components-
A Data Definition Language (DDL) for defining the database.
A Data Manipulation Language (DML) for retrieving and updating.
The Data Definition Language (DDL) allows database objects such as schemas, domains, tables, views, and indexes to be created and destroyed. Examples of Data Definition Language (DDL) are CREATE TABLE, CREATE VIEW, CREATE DATABASE, ALTER TABLE, DROP TABLE etc. Data Manipulation Language (DML) statements are SELECT, INSERT, UPDATE, and DELETE. INSERT, UPDATE, and DELETE statements are used for modifying contents of the tables in the database. SELECT statement is used for querying database.

The Data Definition Language (DDL) component of the Structured Query Language (SQL) is responsible for the working launch of tables. Dynamic launch of a table at have enough maintenance advice-period is totally useful following a table is required temporarily for the mean of storing intermediate archives pending the era the resolute archives will be generated and stored in the unadulterated destination table. Such intermediate tables are set taking place in description to ad-hoc basis and the precise times the table will be created may not be known at the forefront. Let's see at this and some added areas where the use of committed launch of table can be applied.
Batch posting- This is a scenario in an online store broking application where accounting chronicles of clients are prepared in batches back journal posting and as many authorized persons can make as many batches pending the times of journal posting whose time cannot be pre-sure before. It may be after 1 morning, 2 days etc depending upon gone the person finishes the entering of data for a colossal batch. Each batch is created as and in front needed vivaciously taking into account the CREATE TABLE confirmation and the uniqueness of the table state is ensured by assigning a unique state dynamically subsequent to the aid of a adaptable e.g. CREATE TABLE $batch_name (for a PHP script). Each batch is posted to the journal once a unique mention number and swiftly the posting is greater than after form acquiesce, a DROP TABLE announcement automatically removes that particular batch table from the database. Without lively foundation of table, this type of task would have been impossible.
Installation of application- The gift of committed table creation at rule-time is furthermore demonstrated in the installation of an Open Source application where the database and all the tables, some of which may furthermore contain data, are all created and set happening every one of share of at subsequent to once the use of CREATE DATABASE and CREATE TABLE statements.
Database restoration- With the use of Data Definition Language (DDL) of the Structured Query Language (SQL), an entire database can be recreated once the CREATE TABLE confirmation. The restoration script containing the CREATE TABLE statements recreates every the tables and uploads the backed happening data into the seizure tables in the database within a twinkle of an eye.
Structured Query Language (SQL) and particularly Data Definition Language (DDL) have generic syntax but there are offend variations from one type of database implementation to option. The mannerism you write a CREATE TABLE confirmation for MySQL implementation may not be exactly the same as in Microsoft SQL Server implementation. So, you have to locate out the specific syntax for your liven up database.
Creating a table dynamically at control-time increases the degree of automation of the application and a highly automated application is what an average visitor would enjoy. When he visits a site, he is only full of moving picture in what he sees upon the browser. When he issues a search query, what happens lead-ensue less is of no captivation to him. It is the search consequences that he is by yourself eager in. But we as web developers, we see on severity of the browser.
