SQL> select * from T_TEMP_LZY_QYDJ_1;

ORA-29913: an error occurred when calling out ODCIEXTTABLEFETCH ORA-30653: the
rejection limit has been reached
ORA-06512: in “SYS.ORACLE_LOADER”, line 14
ORA-06512: in line 1

Check the external table log T_TEMP_LZY_QYDJ_1_2696_1384.log, which indicates an error:

error processing column ZCLX in row 63 for datafile e: mplsbd.txt
ORA-01401: inserted value too large for column

It turns out that the column width of the table is insufficient!!
