importing a csv file to oracle database

Question

I want to import a .csv file into an oracle database table below, but its not working and the log file is empty without no output.

my shell script is below:

and also the logfile is always empty

below is a sample of the .csv file

SendingFri,LoggingTime,RenewalNumber,TransactionType,Status,Duration
22997186945,2023-07-25-00:05:56.301,23900032093333,Payment,SUCCESS,null
22951547347,2023-07-25-00:04:12.794,23900336289912,Payment,SUCCESS,null

#!/bin/bash

# Oracle Database Connection Details
USERNAME='abc'
PASSWORD="abc"
HOST="myip"
PORT="1521"
SERVICE_NAME="abc"

# CSV File Details
CSV_FILE="/home/hdegboevi/modified5.csv"
TABLE_NAME="myCANALINFORMATION"

# Control File
CONTROL_FILE="my_control_file.ctl"

# Create a control file
cat <<EOF > $CONTROL_FILE
LOAD DATA
INFILE '$CSV_FILE'
APPEND INTO TABLE $TABLE_NAME
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
(
SENDINGFRI,
LOGGINGTIME,
RENEWALNUMBER,
TRANSACTIONTYPE,
STATUS,
DURATON
)
EOF

# Run SQL*Loader
sqlldr $USERNAME/$PASSWORD@$HOST:$PORT/$SERVICE_NAME control=$CONTROL_FILE log=/home/hdegboevi/sqlldr.log  /home/hdegboevi

# Check the log for errors
if grep "ORA-" sqlldr.log; then
    echo "Error occurred during data load. Please check sqlldr.log for details."
else
    echo "Data loaded successfully."
fi

You should have posted target table description; without it, we have to guess datatypes. My lucky guess (according to sample data):

SQL> desc test
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 SENDINGFRI                                         NUMBER
 LOGGINGTIME                                        TIMESTAMP(6)
 RENEWALNUMBER                                      NUMBER
 TRANSACTIONTYPE                                    VARCHAR2(20)
 STATUS                                             VARCHAR2(10)
 DURATION                                           VARCHAR2(20)

which is probably wrong; duration column sounds as if you'd want to put e.g. a number in it (something took 2 seconds to complete), but sample data suggests that you're inserting a string into it (null, in this context, is a string).

With a control file you wrote, result is (in my database)

Record 1: Rejected - Error on table TEST, column LOGGINGTIME.
ORA-01843: not a valid month

Control file, fixed:

LOAD DATA
INFILE *
REPLACE
INTO TABLE test
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
(
SENDINGFRI,
LOGGINGTIME "to_timestamp(:loggingtime, 'yyyy-mm-dd-hh24:mi:ss.ff')",
RENEWALNUMBER,
TRANSACTIONTYPE,
STATUS,
DURATION
)

OK; data is here.

I'd suggest you to first make that part of job correctly (i.e. loading itself), and then create a shell script. I can't assist about that, I don't use any kind of Unix operating systems.

[EDIT, after you posted table description]

Aha; so all columns are varchar2. Even simpler.

SQL> desc test
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 SENDINGFRI                                         VARCHAR2(30)
 LOGGINGTIME                                        VARCHAR2(30)
 RENEWALNUMBER                                      VARCHAR2(30)
 TRANSACTIONTYPE                                    VARCHAR2(30)
 STATUS                                             VARCHAR2(30)
 DURATON                                            VARCHAR2(30)

(I thought it was a typo, "duraton" vs. "duration"; looks like it really is "duraton", whatever that might be).

Control file is trivial:

LOAD DATA
INFILE *
REPLACE
INTO TABLE test
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
(
SENDINGFRI,
LOGGINGTIME,
RENEWALNUMBER,
TRANSACTIONTYPE,
STATUS,
DURATON
)
