What happened

When I try to use seatunnel to synchronize SAP hana data to doris, when partition_column is of date type, an error will be reported.
I checked the code and found that the split value will be converted into timestamp, for example: 2024-02-06 07:12:00 is converted to 1707174720003, then the (param instanceof BigDecimal) judgment will be entered in the createNumberColumnSplitStatement method. I think we should first determine whether the value is a timestamp. If it is a timestamp, then statement.setTimestamp

// here is the source code
else if (param instanceof BigDecimal) {
                statement.setBigDecimal(i + 1, (BigDecimal) param);
            }
