Hi there,

Hoping someone can help me with this, potentially somewhat obscure, problem. I have some data in a text file separated by delimiters, one field of which is a date and time in the form:
ddmmyyyy hhmmss.
I would like to load it into my table in the form mmyy. The data type of the field in question is varchar2 4 bytes. Is there a way I can do this?

Thanks very much,

F

Yes, use the TO_CHAR and TO_DATE functions in your SQL*Loader control file.

SUBSTR() may also help. See "Can one modify data as the database gets loaded?" in the SQL*Loader FAQ.

Hi,

I've had a look at this but still a bit unsure of the syntax (as most of the examples I have come across relate to converting to a different date format, as opposed to converting to an integer). Would you happen to have an example?

Thanks,

F

If
Quote:

Then a simple SUBSTR will do the trick and there are several examples of applying a function in Frank's link, for instance in section "Can one modify data as the database gets loaded?". Read it carefully.

Regards
Michel

Thanks very much, turned out to be more straightforward than I was expecting. For the record, in case anyone is interested, the following now works:

field_name "substr(:field_name, 3,2) ||''|| substr(:field_name, 7,2)",

Thanks for the feedback!

PS: The ''|| looks redundant to me. You can probably remove it.
