# MSSQL Database Plugin HTTP API
The MSSQL Database Plugin is one of the supported plugins for the Database
backend. This plugin generates database credentials dynamically based on
configured roles for the MSSQL database.
## Configure Connection
In addition to the parameters defined by the [Database
Backend](/api/secret/databases/index.html#configure-connection), this plugin
has a number of parameters to further configure a connection.
| Method | Path | Produces |
| :------- | :--------------------------- | :--------------------- |
| `POST` | `/database/config/:name` | `204 (empty body)` |
### Parameters
- `connection_url` `(string: <required>)` - Specifies the MSSQL DSN.
- `max_open_connections` `(int: 2)` - Speficies the name of the plugin to use
for this connection.
- `max_idle_connections` `(int: 0)` - Specifies the maximum number of idle
connections to the database. A zero uses the value of `max_open_connections`
and a negative value disables idle connections. If larger than
`max_open_connections` it will be reduced to be equal.
- `max_connection_lifetime` `(string: "0s")` - Specifies the maximum amount of
time a connection may be reused. If <= 0s connections are reused forever.
