   Confirmed that multiple SQL statements delimited by ';' can be executed as expected. LGTM +1. Merging to master. Thanks @mattyb149 !
   
   Note for those who wonder what the regex `(?<!\\);` means, that is a 'negative look behind'. The regex searches `;` and checks backwards and match only if there is NOT a preceding back-slash (`\\` is an escaped `\`). In short, it doesn't treat escaped semi-colon as a SQL delimiter. The regex does not split statements with `\;`, so that semi-colon can be used within a statement.
