it doesn't work...
.bad file just contain 50 data...
and even .dsc file not contain any data
It is working. The SQLLDR runs for some records and when the record count in BAD file reaches 50 then it stops uploading expecting you to fix the and rerun.
DSC file is empty because NONE of the records are discarded at that point of time.
Hint's to solve this bad records:
1. Check for the date format in the data file if any date column is there. And use the same format in the Control file as well
2. If you are using positions for each column value, then check they are proper.
