Azure MS SQL Server - USE statement is not supported to switch between databases

Hi,
I'm trying to use fluent-plugin-sql with Azure MS SQL Server DB and getting error.

Dockerfile partial config:

```
&& gem install fluent-plugin-sql --no-document \
&& gem install tiny_tds \
&& gem install activerecord-sqlserver-adapter \
```

fluent.conf

```

@type sql
host ...
port 1433
database ...
adapter sqlserver
username ...
password ...

table ...

```

Error in fluentd logs:

```

Looks like Azure SQL Server doesn't support USE command to switch database. Anyone faced and resolved this?
Thanks in advance.

Use the Dockerfile dependency setup and fluent.conf as the reproduction context, then follow the reported ActiveRecord SQL Server and TinyTDS connection stack. Determine how the sql plugin passes the database setting to that connection and confirm the behavior against Azure MS SQL Server. Done means the configured database connection succeeds without the unsupported USE switch.
