I'm trying to insert a full integral time data into a database by using the function "insert",the code is as below

insert into tmp_zgn_huaxc_20220518 (OPERID, BEGINTIME, ENDTIME)
values ('50310',
        to_date('28-05-2022 13:00:00', 'dd-mm-yyyy hh24:mi:ss'),
        to_date('28-05-2022 17:30:00', 'dd-mm-yyyy hh24:mi:ss'));

the result shows successfully，but only a part of the data are show up，the others are missing.The result is as below.

operid begintime endtime
52626 2022-05-28 00:00:00 2022-05-28 00:00:00

There are three DBMS I have tried (postgresql / opengauss / kingbase ),the result is the same.

sql kingbase
