      For a given queryString, get query - a byte array containing the UTF8 representation of that string paramPositions - the byte positions of any '?' positional parameters in query and set the following flags: isInsert - queryString contains 'INSERT' outside of quotes, without one of the characters '();><=-+,' immediately preceding or following isInsertDuplicate - isInsert && queryString contains 'DUPLICATE' outside of quotes, without one of the characters '();><=-+,' immediately preceding or following isMulti - queryString contains text after the last ';' outside of quotes
      static ClientParser rewritableParts​(java.lang.String queryString, boolean noBackslashEscapes)
      For a given queryString, get the fields and flags from parameterParts(String, boolean), and valuesBracketPositions - a two-element list containing the positions of the opening and closing parenthesis of the VALUES block
