看了CommonRdbmsWriter代码 怀疑是Double类型的字段在preparedStatement变成了科学技术法表达, 导致错误
CommonRdbmsWriter.java 426行
```
case Types.SMALLINT:
case Types.INTEGER:
case Types.BIGINT:
case Types.NUMERIC:
case Types.DECIMAL:
case Types.FLOAT:
case Types.REAL:
case Types.DOUBLE:
String strValue = column.asString();
if (emptyAsNull && "".equals(strValue)) {
preparedStatement.setString(columnIndex + 1, null);
} else {
preparedStatement.setString(columnIndex + 1, strValue);
}
break;
```
问题:
1. 为何要把数字类型转化成String?
2. 确定是否这个问题导致同步失败?

Start in CommonRdbmsWriter.java around line 426 and trace the numeric handling used by CommonRdbmsWriter$Task.doOneInsert, then inspect the SQL Server writer path shown in the stack trace. Reproduce the Hive-to-SQL Server case with the DOUBLE value 1.303677E7 and determine whether string binding causes the numeric conversion error. Done means the cause is confirmed or ruled out and the required behavior is documented with coverage for the failing case.
