Connect to SQL Server Express LocalDB
Step 1. Check and create a LocalDB instance
To connect to your LocalDB instance with WebStorm, check if your LocalDB instance is ready for a connection. To do that, locate SqllocalDB.exe and run the following command in a command prompt:
You will see a list of available LocalDB instances on the server.SqllocalDB.exe i
Next, create a LocalDB instance. To create an instance, run the following command:SqlLocalDB create "DEVELOPMENT" 15.0 -s
This command creates an instance of LocalDB named
DEVELOPMENTby using SQL Server 2017 binaries and starts the instance. If you omit
15.0, the version number defaults to the version of the SqlLocalDB utility.
To check an instance state, run this command.SqllocalDB.exe i MSSQLLocalDB
Currently, the instance is running (see the
Statefield). If you have the
Stoppedstate, start the instance by running the following command in the terminal.SqllocalDB.exe s MSSQLLocalDB
Step 2. Create the LocalDB connection
In the Database tool window ( ), click the Data Source Properties icon .Select .
From the Driver list, select Microsoft SQL Server (jTds).
At the bottom of the data source settings area, click the Download missing driver files link. As you click this link, WebStorm downloads drivers that are required to interact with a database. To decrease the size of the installation package and keep driver versions up-to-date, drivers are not bundled with the IDE.
You can specify your own drivers for the data source if you do not want to download the provided drivers. For more information about creating a database connection with your driver, see Add a user driver to an existing connection.
From the Connection type list, select LocalDB.
From the Instance list, select the instance to connect to (for example,
From the Authentication list, select the authentication type:
User & Password requires a username and a password.
Windows credentials requires you to run WebStorm on Windows in the same domain as the Microsoft SQL Server database. Works as the Single-Sign On (SSO).
Domain credentials requires a domain, a username, and a password.
To ensure that the connection to the data source is successful, click the Test Connection link.
