ORA-01841: (full) year must be between -4713 and +9999, and not be 0 tips

Oracle Error Tips by Burleson Consulting (S. Karam)


Question: I have a table with a column having date as 20130324 i.e YYYYMMDD.
When I try to load this data via sqlldr , it gives me error

ORA : 01841.

ORA-01841: (full) year must be between -4713 and +9999, and not be 0

My control file looks like

admidate date 'YYYYMMDD' NULL IF admidate = BLANKS;


Answer: The Oracle docs note this on the ora-01841 error:

ORA-01841: (full) year must be between -4713 and +9999, and not be 0
Cause: Illegal year entered

Action: Input year in the specified range

On Oracle MOSC, a case is present concerning ORA-01841.  The solution is described as follows and includes some information about ORA-01841 and a few associated bugs.

Bug numbers are 944232 and 935135.


Are you trying to load NULL values in records?

If so, can you do a "change all" to make the NULL values NOT NULL

There is lots of good advice on this error on Google.

Can you view the records to load and visually inspect the date formats?

Try this:

admidate     date "YYYYMMDD"    nullif (admidate=BLANKS)

If you are loading a column with a DATE datatype, then you need to use the to_date function:

admidate TO_DATE("admidate",'yyyymmdd') nullif (admidate=BLANKS
