    15  ## Notes
    16  
    17  * 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:
    18    * 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.
    19    * The queries are not executed in any sort of transaction/batch, meaning you are responsible for fixing partial migrations.
