I want to load data file which contains date fields in this format:


but, my oracle NLS_LANG is "Simplified Chinese_China.ZH16GBK", if I specify date format in control file like this:


It will fail, as it expect data like this:

10-八月 -16 // 八月 means august in Chinese

how can I load this data?

  • I'm not sure how the language will factor in, but from a pure English standpoint, your data format mask does not match your data. If your data is '10-Aug-16', then your mask would be 'dd-Mon-yy', not 'dd-Month-yy'. That's assuming the '10' really is the day. And it's long past time to lose the 2-digit years. Legions of guys like me busted our butts to fix that 16 years ago. Don't repeat the mistakes that lead to Y2K.

1 Answer 1


TO_DATE functions accepts the NLS language as an optional parameter .. have you tried pulling it in via SQL*Loader as a CHAR, then do a TO_DATE conversion on it inline?

so your SQL*loader syntax might look like:

    my_date     CHAR  "TO_DATE(:my_date, 'dd-MON-RR', 'NLS_DATE_LANGUAGE=American')"

See if that works any better ??
