ANSISQL

ANSI SQL refers to the American National Standards Institute's standard for the SQL (Structured Query Language) database query language. This standard aims to provide a common syntax and set of commands that can be used across different database management systems. By adhering to ANSI SQL, developers can write code that is more portable and less dependent on the specific vendor of the database being used.

The ANSI SQL standard has evolved over time with various revisions, such as SQL-86, SQL-89, SQL-92, SQL:1999, SQL:2003, SQL:2008, SQL:2011, SQL:2016, and SQL:2019. Each revision introduces new features, data types, and functionalities to the language. While many database systems strive to be compliant with the ANSI SQL standard, they often include proprietary extensions or variations that may not be universally supported. Understanding the core ANSI SQL principles is crucial for effective database interaction.
