Create Azure SQL instance

Follow the instructions from the Azure documentation on how to create a SQL database. The database must be created before Dapr consumes it. The database must be created before Dapr consumes it. The database must be created before Dapr consumes it.

Note: SQL Server state store also supports SQL Server running on VMs.

In order to setup SQL Server as a state store, you need the following properties:

  • Connection String: the SQL Server connection string. For example: server=localhost;user id=sa;password=your-password;port=1433;database=mydatabase;
  • Schema: The database schema to use (default=dbo). Will be created if does not exist
  • Table Name: The database table name. Will be created if does not exist
  • Indexed Properties: Optional properties from json data which will be indexed and persisted as individual column

Create a dedicated user

When connecting with a dedicated user (not sa), these authorizations are required for the user - even when the user is owner of the desired database schema:

  • CREATE TABLE
  • CREATE TYPE
