SQL error 1841 mapping L.TABLE to L.TABLE OCI Error ORA-01841: (full) year must be between -4713 and +9999,

环境：OGG源端10g，目标端11g。初步判断日期格式异常导致。
根据日志，查找源库中年份为0的数据：
SQL> select l.*,to_number(to_char(PAYTODATE,'yyyy')) from L.TABLE l where to_number(to_char(PAYTODATE,'yyyy')) =0;
CONTNO PAYTODATE TO_NUMBER(TO_CHAR(PAYTODATE,'YYYY'))
------------------------------ ------------ ------------------------------------
2017E11122000055 21-DEC-00 0
查找年份为2000的数据：
SQL> select l.*,to_number(to_char(PAYTODATE,'yyyy')) from L.TABLE l where to_number(to_char(PAYTODATE,'yyyy')) =2000;
CONTNO PAYTODATE TO_NUMBER(TO_CHAR(PAYTODATE,'YYYY'))

2018E11060500007 01-JUN-00 2000
2018E11061600010 17-JUN-00 2000
对比发现 PAYTODATE列同为00年份，但格式化后，一条数据位0，其他条数据为2000.异常数据浮出水面。
