load data

infile '/iot/opthb/TIBS_HOME/xcx/test/loadfile.txt'

truncate into table zhicai_record_tmp 

fields terminated by ' ' 

trailing nullcols(src_file_name,create_date,state_date,des_file_name)

用这个模板导入数据时

loadfile.txt:

会出现

Record 9: Rejected - Error on table ZHICAI_RECORD_TMP, column CREATE_DATE.

ORA-01861: literal does not match format string

这种错误,主要是因为日期格式不匹配,这时要对导入的数据进行格式化处理

load data

infile '/iot/opthb/TIBS_HOME/xcx/test/loadfile.txt'

append into table zhicai_record_tmp 

fields terminated by ' ' 

trailing nullcols(src_file_name,

create_date "to_date(:create_date,'yyyymmddhh34miss')",

state_date "to_date(:create_date,'yyyymmddhh34miss')",

des_file_name)

用这个模板导入数据时,便不会出现以上报错
