> when ExecuteSql or QueryDataBaseTable processor trigger below code in
> JdbcCommon.java ,clob would be unreadable code（with Chinese character）
> {code:java}
> if (javaSqlType == CLOB) {
> Clob clob = rs.getClob(i);
> if (clob != null) {
> long numChars = clob.length();
> char[] buffer = new char[(int) numChars];
> InputStream is = clob.getAsciiStream();
> int index = 0;
> int c = is.read();
> while (c >= 0) {
> buffer[index++] = (char) c;
> c = is.read();
> }
> rec.put(i - 1, new String(buffer));
> clob.free();
> } else {
> rec.put(i - 1, null);
> }
> continue;
> }
> {code}
> I konw this can be resoveld by using ExecuteSqlRecord and
> QueryDatabaseTableRecord. Then have new avroWriter(by using controller
> cervice), so I think ,can we change the DefaultAvroSqlWriter to the new
> avroWriter?
