Select Database, Use Statement – SQL

Select Database, Use Statement – SQL When you have multiple databases in your SQL Schema, then before starting your operation, you would need to select a database where all the operations would be performed.

The SQL USE statement is used to select any existing database in SQL schema.

Syntax:

Basic syntax of USE statement is as follows:

USE DatabaseName;

Always database name should be unique within the RDBMS.

Example:

You can check available databases as follows:

SQL> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| AMROOD             |
| TUTORIALSPOINT     |
| mysql              |
| orig               |
| test               |
+--------------------+
6 rows in set (0.00 sec)

Now, if you want to work with AMROOD database, then you can execute the following SQL command and start working with AMROOD database:
