CLOB inserted as varchar2 [message #479427] Sat, 16 October 2010 17:44 Go to next message

I ave a few fields in my flat file which might be a CLOB (not sure how the source is storing the data - need to check on that.) I am trying to load this data into my table column which is a varchar2(4000) . I am able to insert most of the data but few records are rejected because of
Field too long error....

While debugging the problm I manually copied the field from flatfile and inserted into my table - bingo it worked. (The field was not more than 1000 bytes - only a few lines of information )
My question:
When a field is not more than 1000 bytes why couldnt it get inserted as a varchar2?

Note :
I cannot make the table column as CLOB because the problem is not with just one column - I have 10 fields which have this problem . So its not advisable to have 10 CLOB fields in the table......

I have specified OPTIONS (BINDSIZE=256000,READSIZE=256000,ROWS=1)

Is this a known problem?

It would be helpful if you followed Posting Guidelines - http://www.orafaq.com/forum/t/88153/0/

I can only speculate since you posted NOTHING of substance, but only your description of what you think you see.
If/when sqlldr does to correctly see or detect the end of the CLOB, your error would be thrown.

You need to post your table structure, sample data, control file, and log file. A common error is not declaring a size for the field within the control file. If you do not declare a size, then SQL*Loader uses a default size of 255 and rejects anything larger than that, regardless of the size of the column in the table that it is trying to insert into.
