ZhangCheng commented on NIFI-9064:
----------------------------------
Maybe I can fix this by making some change at DataTypeUtils.toTimestamp, sth
like
```
if ("oracle.sql.TIMESTAMP".equals(value.getClass().getName())) {
String orcValue = value.toString();
String orcFormat = "yyyy-MM-dd HH:mm:ss.SSS";
DateFormat dateFormat = getDateFormat(orcFormat);
if (orcValue.length() > orcFormat.length()) {
orcValue = orcValue.substring(0, orcValue.indexOf(".") + 4);
}
if (orcValue.length() < orcFormat.length()) {
int supplement = orcFormat.length() - orcValue.length();
while (supplement > 0) {
orcValue += '0';
supplement -- ;
}
}
try {
final java.util.Date utilDate = dateFormat.parse(orcValue);
return new Timestamp(utilDate.getTime());
} catch (ParseException e) {
throw new IllegalTypeConversionException("Could not convert
value [" + value
+ "] of Oracle DB to Timestamp for field " + fieldName
+ " because the value is not in the expected date format: "
+ orcFormat);
}
}
```
