ON_ERROR = { SKIP | INS_NULL | QUIT | END_ALL | PROMPT };
If ON_ERROR is set to SKIP, a record that contains invalid data is skipped and Import goes on to the next record. If ON_ERROR is set to INS_NULL, a NULL is placed in the field if the field is nullable. If ON_ERROR is set to QUIT, the batch import will be terminated if invalid data is found. If ON_ERROR is set to END_ALL, all batch import processing is terminated. If ON_ERROR is set to PROMPT, the user is prompted for further action.
