MSSQL

Microsoft SQL Server Data Connector

Microsoft SQL Server is a relational database management system developed by Microsoft.

The Microsoft SQL Server Data Connector enables federated/accelerated SQL queries on data stored in MSSQL databases.

Limitations

1. The connector supports SQL Server authentication (SQL Login and Password) only.

2. Spatial types (geography) are not supported, and columns with these types will be ignored.

datasets:
  - from: mssql:path.to.my_dataset
    name: my_dataset
    params:
      mssql_connection_string: ${secrets:mssql_connection_string}

Configuration

from

The from field takes the form mssql:database.schema.table where database.schema.table is the fully-qualified table name in the SQL server.

name

The dataset name. This will be used as the table name within Spice.

Example:

datasets:
  - from: mssql:path.to.my_dataset
    name: cool_dataset
    params: ...

SELECT COUNT(*) FROM cool_dataset;

+----------+
| count(*) |
+----------+
| 6001215  |
+----------+

params

The data connector supports the following params. Use the secret replacement syntax to load the secret from a secret store, e.g. ${secrets:my_mssql_conn_string}.

Parameter Name	Description
mssql_connection_string	The ADO connection string to use to connect to the server. This can be used instead of providing individual connection parameters.
mssql_host	The hostname or IP address of the Microsoft SQL Server instance.
mssql_port	(Optional) The port of the Microsoft SQL Server instance. Default value is 1433.
mssql_database	(Optional) The name of the database to connect to. The default database (master) will be used if not specified.
mssql_username	The username for the SQL Server authentication.
mssql_password	The password for the SQL Server authentication.
mssql_encrypt	(Optional) Specifies whether encryption is required for the connection. true: (default) This mode requires an SSL connection. If a secure connection cannot be established, server will not connect. false: This mode will not attempt to use an SSL connection, even if the server supports it. Only the login procedure is encrypted.
mssql_trust_server_certificate	(Optional) Specifies whether the server certificate should be trusted without validation when encryption is enabled. true: The server certificate will not be validated and it is accepted as-is. false: (default) Server certificate will be validated against system's certificate storage.

Example

datasets:
  - from: mssql:SalesLT.Customer
    name: customer
    params:
      mssql_host: mssql-host.database.windows.net
      mssql_database: my_catalog
      mssql_username: my_user
      mssql_password: ${secrets:mssql_pass}
      mssql_encrypt: true
      mssql_trust_server_certificate: true
