MySQL Server, the world's most popular open source database, and MySQL Cluster, a real-time, open source transactional database. www.mysql.com/ View license Here are the primary differences between SQL and MySQL: While SQL is a language used for operating different relational databases, MySQL boasts of being the first open-source relational database in the early 90s.

The JOIN statement in MySQL is a method of linking data between several tables in a database based on common column’s values in those tables.. Common values are usually the same column name and data type present in the tables being joined. Oracle provides its MySQL database server and MySQL Client Libraries under a dual license model designed to meet the development and distribution needs of both commercial distributors (such as OEMs, ISVs and VARs) and open source projects.
TLS is sometimes referred to as SSL (Secure Sockets Layer) but MySQL does not actually use the SSL protocol for encrypted connections because its encryption is weak (see Section 6.3.2, “Encrypted Connection TLS Protocols and Ciphers”). TLS uses encryption algorithms to ensure that data received over a public network can be trusted. Passwords or other sensitive values supplied as arguments to encryption functions are sent as cleartext to the MySQL server unless an SSL connection is used. Also, such values appear in any MySQL logs to which they are written.
