Oracle Error Message
SQL*Loader-00284: Warning: Input data file string specified multiple times.
Reason for the Error
The same input datafile is loaded multiple times. This can occur if the INFILE keyword is placed out of order in the load syntax statement, which causes the filename of the first datafile loaded to default to the name of the control file with an extension or file type of DAT.
Solution
Check that INFILE keyword is not placed after one of these – BADFILE/BADDN/DISCARDFILE/DISCARDDN/DISCARDS.
