ANSI SQL stands for American National Standards Institute Structured Query Language. It is a standard language for relational database management systems (RDBMS) that follows the ANSI/ISO SQL standard.
ANSI SQL defines a set of syntax rules and commands that are used to interact with relational databases. It provides a standardized way to create, retrieve, update, and delete data in a database.
The ANSI SQL standard is maintained and updated by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). It ensures that SQL is consistent across different database platforms and allows applications to be portable between different systems.
ANSI SQL includes various features such as data definition language (DDL) statements for creating and modifying database objects, data manipulation language (DML) statements for querying and modifying data, and data control language (DCL) statements for managing user permissions and security.
Implementations of ANSI SQL may vary among different database vendors, but they all adhere to the basic syntax and functionality defined by the standard. Some popular relational database systems that support ANSI SQL include Oracle, MySQL, Microsoft SQL Server, and PostgreSQL.
