#### MS SQL
Use the same `db_url` as for the `recorder` integration. Change `DB_NAME` to the name that you use as the database name, to ensure that your sensor will work properly. Be sure `username` has enough rights to access the sys tables.

```yaml
sensor:
- platform: sql
db_url: "mssql+pyodbc://username:password@SERVER_IP/DB_NAME?charset=utf8;DRIVER={FreeTDS};Port=1433;"
queries:
- name: DB size
query: "SELECT TOP 1 SUM(m.size) * 8 / 1024 as size FROM sys.master_files m INNER JOIN sys.databases d ON d.database_id=m.database_id WHERE d.name='DB_NAME';"
column: 'size'
unit_of_measurement: MiB
