MySQL is an open source relational database management system that is widely used in modern web applications. As the amount of data continues to increase, especially in large enterprise applications, managing and querying database tables becomes increasingly critical. Therefore, it is very important for developers to master the skills of MySQL query tables.
In MySQL, the methods of querying database tables can be divided into two types: the graphical user interface-based method and the command line-based method. These two methods will be introduced below.
1. Method based on graphical user interface
As a management tool based on graphical user interface, MySQL provides many visualization functions that can easily operate and query database tables. The following are the query table steps using MySQL Workbench:
SELECT * FROM customers;
2. Command line-based method
Command line-based query is one of the most commonly used methods by MySQL database administrators and advanced users. Here are the steps to query a table using the command line:
mysql -h localhost -u root -p
-h: The address of the MySQL server, if using locally , the address can be "localhost";
-u: user name;
-p: user's password description requires a password.
USE database_name;
where database_name is the name of the database you want to use.
SELECT * FROM customers;
Summary:
MySQL is a widely used relational database management system. Querying database tables is an important function of using MySQL. MySQL provides query methods based on graphical user interface and command line. MySQL Workbench is a convenient management tool based on a graphical user interface that makes querying tables very easy, and the command line query method is a favorite query method among MySQL administrators and advanced users. Proficient use of these methods can help developers query and process MySQL database tables more efficiently.
