SQL和mysql有什么区别

Question

Can anyone explain me what is the difference between SQL and MYSQL with some examples. I am new to databases. I was wondering to know

Answer 1

SQL is a language for querying databases and MySQL is an open source database product.

SQL is used for accessing, updating and maintaining data in a database and MySQL is an RDBMS that allows users to keep the data that exists in a database organized.

SQL does not change (much), as it is a language. MySQL updates frequently as it is a piece of software.

Simple Example for SQL: SELECT * FROM Customers;

Simple example for MYSQL: Start the command-line tool mysql and select a database:

$> mysql your-database-name
