When working with different database management systems (DBMS) like MySQL, PostgreSQL, Oracle, or others, it’s important to have a consistent and efficient method of accessing and manipulating data. One popular way to interact with DBMS is through the command-line interface (CLI). In this article, we will explore how to use the SQL CLI with different DBMS.

MySQL CLI

MySQL provides a command-line client tool called mysql to interact with its database. To start the MySQL CLI, open your terminal and enter the following command:

mysql -u <username> -p

Replace <username> with your MySQL username. You will be prompted to enter your MySQL password. Once authenticated, you can start executing SQL queries directly from the CLI.

PostgreSQL CLI

Similar to MySQL, PostgreSQL also offers a command-line client tool called psql for interacting with its database. To open the PostgreSQL CLI, open your terminal and enter the following command:

psql -U <username> -d <database>

Replace <username> with your PostgreSQL username and <database> with the name of the database you want to connect to. Enter your password when prompted, and you will be ready to issue SQL commands.

Oracle CLI

Oracle Database provides a command-line interface called SQLPlus. To run SQLPlus, open your terminal and type the following command:

sqlplus <username>/<password>@<database>

Replace <username> with your Oracle username, <password> with your password, and <database> with the database name you want to connect to. Once connected, you can start executing SQL statements.

Other DBMS CLI

Different DBMS have their own specific CLI tools. Some other popular ones include Microsoft SQL Server’s sqlcmd CLI and SQLite’s sqlite3 CLI. Refer to the respective documentation for the specific CLI commands and options for these DBMS.

Conclusion

Using the CLI to interact with different DBMS can provide a quick and powerful way to manage your databases. Whether you are working with MySQL, PostgreSQL, Oracle, or other DBMS, the command-line interface allows you to execute SQL commands efficiently. By becoming familiar with the CLI tools for these DBMS, you can work seamlessly across different database environments.
