SQL Loader Not Loading Data

Question

According to sql loaders log file, I was successful in loading my data into a table. However the table does not show any values loaded - all empy.
Here's my table:
SQL> desc patients
Name Null? Type
PATIENT_ID NOT NULL NUMBER(38)
MEDSUBSCRIBERID VARCHAR2(200)
MEDMEMBERID VARCHAR2(50)
MEDDEPSEQDESC VARCHAR2(50)
MEDMEMBERGENDER VARCHAR2(50)
MEDMEMBERDOB DATE
MEDDEPSEQCODE VARCHAR2(50)
NETWORKID NUMBER(38)
NETWORKCODE VARCHAR2(50)
PATIENTAGE NUMBER(38)
PATIENTNAME VARCHAR2(50)
PATIENTLASTNAME VARCHAR2(50)
PATIENTSEX VARCHAR2(50)
PATIENTSSN VARCHAR2(50)
INTMEDSUBSCRIBERID VARCHAR2(50)
DATE_VALUE_ID NUMBER(38)
DOB VARCHAR2(50)
AGE_GROUP_ID NUMBER(38)
ORGANIZATIONNETWORK_ID NUMBER(38)
ORGANIZATION_ID NUMBER(38)
ORGANIZATIONCODE VARCHAR2(50)
NETWORKID_HOLD NUMBER(38)
PATIENTRELATION VARCHAR2(50)
Here's my SQL Loader Control File:
LOAD DATA
INFILE 'patients.dat'
APPEND
INTO TABLE PATIENTS
FIELDS TERMINATED BY '|'
TRAILING NULLCOLS
PATIENT_ID INTEGER(8) NULLIF(PATIENT_ID=BLANKS)

Here's data file that I'm trying to load:
2|001321666|00132156801||M|1944-01-22 00:00:00||42|7215||Donald|Duck||||52616|19440666|4|42|2|WELLS|42|E

And, my log file after executing sql loader successfully but the data does not load:
Table PATIENTS:
3 Rows successfully loaded.
0 Rows not loaded due to data errors.
0 Rows not loaded because all WHEN clauses were failed.

Answer 1

Very strange.
Did you connect as the same user as SQL*Loader when you checked the table?
Is it possible that someone else deleted the data?
