Oracle Error Message
KUP-11003: bad data encountered while reading from file string
Reason for the Error
There was a datatype conversion error while attempting to convert the data in the data file to match the datatype of a column in the external table. The message that follows this one displays the name of the column and the start of the data for the column that could not be converted. The row containing the bad data is rejected and not included as a row in the external table.
Solution
If the row containing the bad data should not be filtered out, then modify the definition of the external table so that the datatypes of the columns match the datatypes of the fields in the data file.
