SQL stands for Structured Query Language. In English, read as ordinary SQL Sequel or ES-KYU-EL. This is standard language used to access relational data base.
SQL standard was first defined by the ISO (International Standards Organization) and ANSI (the American National Standard), sengan known as SQL86. Over time, a number of new standards have been established.
We have a lot of database software that uses SQL as a command to access the data include:
* DB2
* Ingres
* Informix
* Oracle
* Microsoft Access
* MySQL
* PostgresSQL
* Rdb
* Sybase
In practice very berpariasi SQL implementations. Not all of the SQL features supported by the software vendor. Some commands have a slightly different SQL. Some features are reserved for the future.
MySql as the database server also supports the SQL commands. In particular, MYQL also added a number of functions that make SQL commands in MySQL is vary .. This course will provide the flexibility in accessing the data base for instance: to take hours now on the server.
Commands that can be understood by the mSQL database server is called the statement. The statement is a command that can be done by mSQL with features-end with a semicolon (;).
Once you enter the point-point and hit the enter key, the client program will immediately send MYSQL kedatabase MySQL and mSQL servers will immediately respond.
