Structured Query Language (SQL) facilitates reading and displaying the contents of a database's fields and tables. Database are collections of tables with rows and columns that contain valuable and relevant data. The language is mainly used to create databases, store data in tables, modify, extract, and perform operations.

A discussion of SQL data types is presented in this article.

Each column, expression, local variable, and parameter in Database Management System (DBMS) has corresponding data types. Various types of data can be stored in an object, such as integer data,  monetary data, character data, date and time data, and binary strings. The data types in each database can be categorized into six main categories.
