SQL is a language that is used to operate your database whereas MySQL was one of the first open-source databases available in the market.SQL is a query language, whereas MySQL is a relational database that uses SQL to query a database. Authorization: The SQL DDL includes commands for specifying access rights to relations and viewįollowing are the key differential points between SQL and MySQL.Embedded SQL and dynamic SQL: Embedded and dynamic SQL define how SQL statements can be embedded within general-purpose programming languages, such as C, C++, and java.Transaction control: SQL includes commands for specifying the beginning and end of transactions.View definition: The SQL DDL includes commands for defining views.Updates that violate integrity constraints are disallowed Integrity: The SQL DDL includes commands for specifying integrity constraints that the data stored in the database must satisfy.Data-manipulation language (DML): The SQK DML provides the ability to query information from the database and to insert tuples into, delete tuples from, and modify tuples in the database.Data-definition language (DDL): The SQL DDL provides commands for defining relation schemas, deleting relations, and modifying relation schema.SQL is semantically easy to understand and learn and also it can be used to access large amounts of data directly so it is commonly used by engineers in software development, and popularly used by data analysts also SQL allows users to create, read, manipulate, and change data. SQL is the most common method of dealing with data in databases today. The Sequel language has evolved since then, and its name has changed to SQL This language originally called Sequel was implemented as part of the System R project in the early 1970s. SQL (Structured Query Language), is a standard language that is designed for managing data in a relational database. The term "relational database" refers to the fact that the tables within it "relate" to one another-they contain common identifiers that allow information from multiple tables to be combined easilyĪLSO READ: SQL DISTINCT Explained The real power of SQL, however, comes from working with data from multiple tables at once. Since a table is a collection of such relationships, there is a close correspondence between the concept of the table and the mathematical concept of relation, from which the relational data takes its name A row in a table represents a relationship among a set of values. Relational database Consists of a collection of relations, each of which is assigned a unique name.
