Firebird is an open-source SQL relational database management system that runs on Linux, Windows, and several Unix platforms. In this comprehensive guide, we’ll delve into how you can create a database using isql and DbSchema.


Before we proceed, ensure that you have the following:

  1. A system with Firebird installed. To install Firebird visit Install firebird
  2. DbSchema installed if you intend to use this tool. To install DbSchema visit DbSchema
  3. Basic understanding of SQL.

Creating a Database in isql

Step 1: First, open your command prompt or terminal.

Step 2: Type in the command below to navigate to your Firebird bin directory:

cd /path/to/firebird/bin

Step 3: Type isql in the terminal to open the ISQL tool.

Step 4: To create a database, use the CREATE DATABASE command as shown below:

CREATE DATABASE 'localhost:/path/to/database/dbname.fdb' user 'SYSDBA' password 'masterkey';

Replace ‘/path/to/database/dbname.fdb’ with your desired path and database name. SYSDBA and masterkey are the default user and password respectively.

After executing this command, you should see the following response, indicating that the database was created successfully:

Statement executed.

Creating a Database in DbSchema

Step 1: Open DbSchema and click on the Connect button. A dialog box will appear.

Step 2: In the dialog box, select Firebird as the database type.

Step 3: In the RDBMS settings, enter the necessary details:

  • Host: localhost
  • Database: the desired name of your database
  • User: SYSDBA
  • Password: masterkey

Step 4: Under the Action tab, select Create Database.

Step 5: Click on the Test Connection button to ensure your settings are correct. If everything is correct, a success message will appear.

Step 6: Click on the Connect button. The DbSchema window will open, and your database will be displayed in the left-hand panel.
