You can use the SQL command use to select a database.
Example. Here is an example to select a database called TUTORIALS − [root@host]# mysql -u root -p Enter password:****** mysql> use TUTORIALS; Database changed mysql> ...
The USE statement in SQL is used to specify the name of the database we want to select. After selecting the database, we can perform various operations on it such as creating tables, inserting data, updating data, and deleting data.
We can create a new database in MySQL by using the CREATE DATABASE statement with the below syntax: CREATE DATABASE [IF NOT EXISTS] database_name. [CHARACTER SET charset_name] [COLLATE collation_name];
The most common way to get a list of the MySQL databases is by using the mysql client to connect to the MySQL server and run the SHOW DATABASES command. If you haven't set a password for your MySQL user you can omit the -p switch.
First, specify the name of the database in which the table is created. The database_name must be the name of an existing database. If you don't specify it, the database_name defaults to the current database. Second, specify the schema to which the new table belongs.
Start SQL Server Management Studio. The first time you run SSMS, the Connect to Server window opens. If it doesn't open, you can open it manually by selecting Object Explorer > Connect > Database Engine. For Server type, select Database Engine (usually the default option).
To start MySQL service and server, open the Run dialog (Windows key + R) and type in services. msc. Once the Services Window opens, find the SQL Server service. The service name starts with SQL Server followed by the version.
Use the following query to show MySQL users created in the database server: SELECT user FROM mysql. user; As a result, you will see the list of all the users that have been created in MySQL.
We use the SELECT * FROM table_name command to select all the columns of a given table. In the following example we are selecting all the columns of the employee table. mysql> SELECT * FROM employee; And we get the following output.
MySQL has no limit on the number of databases. The underlying file system may have a limit on the number of directories. MySQL has no limit on the number of tables.
The syntax to get all table names with the help of SELECT statement. mysql> use test; Database changed mysql> SELECT Table_name as TablesName from information_schema. tables where table_schema = 'test'; Output with the name of the three tables.
The USE statement tells MySQL to use the named database as the default (current) database for subsequent statements. This statement requires some privilege for the database or some object within it.
