oracle匯入檔案時,日期格式問題

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)

用這個模板匯入資料時

loadfile.txt:

會出現record 9: rejected - error on table zhicai_record_tmp, column create_date.

ora-01861: literal does not match format string

這種錯誤,主要是因為日期格式不匹配,這時要對匯入的資料進行格式化處理

load data

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

fields terminated by ' '

trailing nullcols(src_file_name,

create_date "to_date(:create_date,'yyyymmddhh24miss')",

state_date "to_date(:create_date,'yyyymmddhh24miss')",

des_file_name)

用這個模板匯入資料時,便不會出現以上報錯
