| URL Query | Description |
|------------|-------------|
| `x-migrations-table`| Name of the migrations table |
| `database` | The name of the database to connect to |
| `username` | The user to sign in as |
| `password` | The user's password |
| `host` | The host to connect to. |
| `port` | The port to bind to. |
| `x-multi-statement` | false | Enable multiple statements to be ran in a single migration (See note below) |
## Notes
* The Clickhouse driver does not natively support executing multipe statements in a single query. To allow for multiple statements in a single migration, you can use the `x-multi-statement` param. There are two important caveats:
* This mode splits the migration text into separately-executed statements by a semi-colon `;`. Thus `x-multi-statement` cannot be used when a statement in the migration contains a string with a semi-colon.
* The queries are not executed in any sort of transaction/batch, meaning you are responsible for fixing partial migrations.
