SQL USE


  SQL > Table Manipulation > USE

The USE keyword is used to select a database in MySQL and SQL Server. The syntax is as follows:

USE "Database Name"

For example, if you want to connect to a database called "Scores", you can type in the following:

USE Scores;

In MySQL, you can access tables in multiple databases by specifying [Database Name].[Table Name]. If the table you want to access is currently in the database you use, there is no need to specify the database name.

For example, if you want to access table "Course_110" from database "Scores" and table "Students" from database "Personnel", you can type in the following:

USE Scores;

SELECT ...
FROM Course_110, Personnel.Students
WHERE ...
;
