SQL Loader function and nullif issue [message #364682]

I am trying to load a date field that is mm/dd/yyyy 0:00:00, I need to truncate the time element and also account for the field being blank.

this is the function in the control file but it is not working

"trunc(to_date(:for_dt,'MM/DD/YYYY HH24:MI:SS')) NULLIF for_dt=BLANKS",

Can NULLIF not be used with a function?

Thanks

I don't know but you don't need to truncate the date if it is always "0:00:0" in your file as trunc is just putting this time along with the date.

we could not get the date to load with the time element and we did not need it anyway so I was trying to remove it from the file. Is there a specific data type that sqlloader will recognize, I tried timestamp but I received a loader error.

Sorry, I don't understand, do you have a real time or 0:00:00 in your file?
What is the format of your file?
Could you post control file and a line of data file?

LOAD DATA
APPEND
INTO TABLE xxxxx.xxx_xxxxxx_data
fields terminated by "," optionally enclosed by '"'
TRAILING NULLCOLS
(fileNo,
file_pos_orig,
file_owner,
file_type,
file_type_orig,
file_dt "trunc(to_date(:file_dt,'MM/DD/YYYY HH24:MI:SS')) NULLIF :file_dt=BLANKS",
file_line_amt)

Data:

9999999999,1,2,2,2,2,8/28/1995 0:00:00,,

some of the date fields are empty so they will just show as ,, like the last field in the data.

file_dt "to_date(:file_dt,'MM/DD/YYYY HH24:MI:SS')" NULLIF (:file_dt=BLANKS),

or the opposite, I don't know if order matters:

file_dt NULLIF (:file_dt=BLANKS) "to_date(:file_dt,'MM/DD/YYYY HH24:MI:SS')",

Order matters and don't use : with NULLIF:

file_dt NULLIF file_dt=BLANKS "trunc(to_date(:file_dt,'MM/DD/YYYY HH24:MI:SS'))",
