If you are using Oracle database, at some point you might have to deal with uploading data to the tables from a text file.
This article provides 10 practical examples on how to upload data from a flat file to Oracle tables.
Input data file for SQL*Loader
This is the input text file that contains the data that needs to be loaded into an oracle table. Each and every records needs to be in a separate line, and the column values should be delimited by some common delimiter character. For some of the examples mentioned below, we’ll use the following employee.txt file to upload the data to the employee table.
$ cat employee.txt 100,Thomas,Sales,5000 200,Jason,Technology,5500 300,Mayla,Technology,7000 400,Nisha,Marketing,9500 500,Randy,Technology,6000 501,Ritu,Accounting,5400
SQL*Loader Control File
This contains the instructions to the sqlldr utility. This tells sqlldr the location of the input file, the format of the input file, and other optional meta data information required by the sqlldr to upload the data into oracle tables.
$ cat example1.ctl load data infile '/home/ramesh/employee.txt' into table employee fields terminated by "," ( id, name, dept, salary )
The above control file indicates the following:
- infile – Indicates the location of the input data file
- into table – Indicates the table name where this data should be inserted
- fields terminated by – Indicates the delimiter that is used in the input file to separate the fields
- ( id, name, dept, salary ) – Lists the name of the column names in the table into which the data should be uploaded
1. Basic Upload Example Using SQL*Loader
First, create the employee table as shown below.
SQL> create table employee ( id integer, name varchar2(10), dept varchar2(15), salary integer, hiredon date )
Next create the control file that explains what needs to be upload and where.
$ cat sqlldr-add-new.ctl load data infile '/home/ramesh/employee.txt' into table employee fields terminated by "," ( id, name, dept, salary )
Note: If you have the values inside the data file enclosed with double quote, use this in your control file: fields terminated by “,” optionally enclosed by ‘”‘
Note: If you don’t have the table created, you’ll get the following error message:
SQL*Loader-941: Error during describe of table EMPLOYEE ORA-04043: object EMPLOYEE does not exist
You can pass the userid and password to the sqlldr command using any one of the following format. As you see below, both of these will prompt you for control file location, as it was not given in the command line.
$ sqlldr scott/tiger (or) $ sqlldr userid=scott/tiger control = SQL*Loader-287: No control file name specified.
Execute the sqlldr command to upload these new record to the empty table by specifying both uid/pwd and the control file location as shown below.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-add-new.ctl Commit point reached - logical record count 5
Verify the the records are created in the database
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON
---------- ---------- --------------- ---------- -------
100 Thomas Sales 5000
200 Jason Technology 5500
300 Mayla Technology 7000
400 Nisha Marketing 9500
500 Randy Technology 6000
This will create the output log file in the same name as the data file, but with the .log extension (instead of .ctl). Partial output shown below.
$ cat sqlldr-add-new.log Control File: /home/ramesh/sqlldr-add-new.ctl Data File: /home/ramesh/employee.txt Table EMPLOYEE: 5 Rows successfully loaded. 0 Rows not loaded due to data errors. 0 Rows not loaded because all WHEN clauses were failed. 0 Rows not loaded because all fields were null. Elapsed time was: 00:00:00.04 CPU time was: 00:00:00.00
If you are new to Oracle database, and like to install it, follow this Oracle 11g installation guide.
2. Inserting Additional Records
Let us say you want to add two new employees to the employee table from the following newemployee.txt file.
$ vi newemployee.txt 600,Ritu,Accounting,5400 700,Jessica,Marketing,7800
If you create a similar control file like the previous example, you might get the following error message.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-add-more.ctl SQL*Loader-601: For INSERT option, table must be empty. Error on table EMPLOYEE
The above indicates that the table should be empty before you can upload data using sql*loader.
If you like to insert more data to the tables without having to delete the existing rows, use the “append’ command as shown in the following control file.
$ vi sqlldr-append-more.ctl load data infile '/home/ramesh/newemployee.txt' append into table employee fields terminated by "," ( id, name, dept, salary )
Now, if you do sqlldr this will append the data.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-append-more.ctl Commit point reached - logical record count 2
Verify that the records are appended successfully
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON
---------- ---------- --------------- ---------- -------
100 Thomas Sales 5000
200 Jason Technology 5500
300 Mayla Technology 7000
400 Nisha Marketing 9500
500 Randy Technology 6000
600 Ritu Accounting 5400
700 Jessica Marketing 7800
3. Data inside the Control File using BEGINDATA
You can also specify the data directly inside the control file itself using BEGINDATA keyword. i.e Anything that comes after BEGINDATA will be treated as data to be uploaded to the table as shown below.
$ cat sqlldr-add-new-with-data.ctl load data infile * into table employee fields terminated by "," ( id, name, dept, salary ) begindata 100,Thomas,Sales,5000 200,Jason,Technology,5500 300,Mayla,Technology,7000 400,Nisha,Marketing,9500 500,Randy,Technology,6000
Note: The infile will say ‘*’ in this case, as there is no input data file name for this example.
Execute sqlldr to upload the data from the control file.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-add-new-with-data.ctl
4. Date format and Different Delimiter
This example shows how to specify a date format in the control file and how to handle different delimiters in a data file
The following example has different delimiters ($ after name, ^ after department).
$ cat employee-date.txt 100,Thomas$Sales^5000,31-JAN-2008 200,Jason$Technology^5500,01-Feb-2005 300,Mayla$Technology^7000,10-Aug-2000 400,Nisha$Marketing^9500,12-Dec-2011 500,Randy$Technology^6000,01-JAN-2007
Create the following control file and indicate the field delimiters for each and every field using “terminated by” as shown below.
$ cat sqlldr-date.ctl load data infile '/home/ramesh/employee-date.txt' into table employee fields terminated by "," ( id, name terminated by "$", dept terminated by "^", salary, hiredon DATE "dd-mon-yyyy" )
Load the data using sqlldr as shown below.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-date.ctl
Verify that the data got loaded properly as shown below.
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON
---------- ---------- --------------- ---------- ---------
100 Thomas Sales 5000 31-JAN-08
200 Jason Technology 5500 01-FEB-05
300 Mayla Technology 7000 10-AUG-00
400 Nisha Marketing 9500 12-DEC-11
500 Randy Technology 6000 01-JAN-07
5. Fixed Length Data Upload
If you have a data file without data that are fixed length (i.e without any delimiter), you can use this example to upload this data.
For this example, let us use the following file which has data that are of fixed length. For example, 1st three characters are always employee number, Next 5 characters are always employee name, etc.
$ cat employee-fixed.txt 200JasonTechnology5500 300MaylaTechnology7000 400NishaTechnology9500 500RandyTechnology6000
Create the following control file, where you specific the position of each and every field as shown below usig the “Position(start:end)” syntax.
$ cat sqlldr-fixed.ctl load data infile '/home/ramesh/employee-fixed.txt' into table employee fields terminated by "," ( id position(1:3), name position(4:8), dept position(9:18), salary position(19:22) )
Load this fixed length data using the sqlldr as shown below.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-fixed.ctl
Verify that the data got loaded.
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON
---------- ---------- --------------- ---------- ---------
200 Jason Technology 5500
300 Mayla Technology 7000
400 Nisha Technology 9500
500 Randy Technology 6000
6. Change the data during upload
You can also massage the data and change it during upload based on certain rules.
In the following control file:
- id is incremented by 999 before uploading. i.e if the emp id is 100 in the data file, it will be loaded as 1099
- Convert the name to upper case and load it. This uses the upper function.
- If the department contains the value “Technology” change it to “Techies”. This uses decode function
$ cat sqlldr-change-data.ctl load data infile '/home/ramesh/employee.txt' into table employee fields terminated by "," ( id ":id+999", name "upper(:name)", dept "decode(:dept,'Technology','Techies', :dept)", salary )
Load the data using this control file which will massage the data before uploading it.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-change-data.ctl
Verify that the data got changed while loading as per our rules.
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON
---------- ---------- --------------- ---------- ---------
1099 THOMAS Sales 5000
1199 JASON Techies 5500
1299 MAYLA Techies 7000
1399 NISHA Marketing 9500
1499 RANDY Techies 6000
7. Load data from multiple files
To load data from multiple files, you just have to specify multiple infile in the control file.
The following control file loads data from two different data files (employee.txt and newemployee.txt) to the employee table.
$ sqlldr-add-multiple.ctl load data infile '/home/ramesh/employee.txt' infile '/home/ramesh/newemployee.txt' into table employee fields terminated by "," ( id, name, dept, salary )
Load the data using this control file which will upload data from multiple data files as shown below.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-add-multiple.ctl Commit point reached - logical record count 5 Commit point reached - logical record count 7
8. Load data to Multiple Tables
Create another table called bonus which will have employee id and bonus columns.
create table bonus
( id integer,
bonus integer
);
Create the employee-bonus.txt data file that contains the fields: id, name, department, salary, bonus
$ cat employee-bonus.txt 100 Thomas Sales 5000 1000 200 Jason Technology 5500 2000 300 Mayla Technology 7000 2000 400 Nisha Marketing 9500 1000 500 Randy Technology 6000 3000
Create the control file as shown below, which will upload the data from the above file to two different tables. As shown below, you should have two “into table” commands, and specify the position of the data which needs to be used to upload the data to that column.
$ cat sqlldr-multiple-tables.ctl load data infile '/home/ramesh/employee-bonus.txt' into table employee ( id position(1:3), name position(5:10), dept position(12:21), salary position(23:26)) into table bonus ( id position(1:3), bonus position(28:31))
Load the data to multiple tables using this control file as shown below.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-multiple-tables.ctl
Verify that the data got loaded to multiple tables successfully.
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON
---------- ---------- --------------- ---------- ---------
100 Thomas Sales 5000
200 Jason Technology 5500
300 Mayla Technology 7000
400 Nisha Marketing 9500
500 Randy Technology 6000
SQL> select * from bonus;
ID BONUS
---------- ----------
100 1000
200 2000
300 2000
400 1000
500 3000
9. Handling Bad (Rejected) Records
In the following example, we have two bad records. Employee id 300 and 500 has salary column which is not numeric.
$ cat employee-bad.txt 100,Thomas,Sales,5000 200,Jason,Technology,5500 300,Mayla,Technology,7K 400,Nisha,Marketing,9500 500,Randy,Technology,6K
Use the following control file for this example.
$ cat sqlldr-bad.ctl load data infile '/home/ramesh/employee-bad.txt' into table employee fields terminated by "," ( id, name, dept, salary )
Load the data (including the invalid records) using this control file as shown below.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-bad.ctl Commit point reached - logical record count 5
As you see from the abvoe output, it still says “logical record count 5”, but you should check the log files to see if it has rejected any records.
The log file indicates that 2 records are rejected as shown below:
Control File: /home/ramesh/sqlldr-bad.ctl Data File: /home/ramesh/employee-bad.txt Bad File: /home/ramesh/employee-bad.bad Discard File: none specified Table EMPLOYEE: 3 Rows successfully loaded. 2 Rows not loaded due to data errors.
By default the rejected records are stored in a file that has the same name as the data file (but with .bad extension)
$ cat employee-bad.bad 300,Mayla,Technology,7K 500,Randy,Technology,6K
As you see below, the employee table has only 3 records (as 2 of them were rejected).
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON
---------- ---------- --------------- ---------- ---------
100 Thomas Sales 5000
200 Jason Technology 5500
400 Nisha Marketing 9500
10. Load Specific Rows from a datafile
If you want to load only a specific records from a data file use the WHEN in the control file.
Add the line “when” next to “into table” line. In the following control file, the when clause indicates that it will load only the records that have dept as “Technology”.
$ cat sqlldr-when.ctl load data infile '/home/ramesh/employee.txt' into table employee when dept = 'Technology' fields terminated by "," ( id, name, dept, salary )
Load the selective data (only the “Technology” records) using this control file as shown below.
$ sqlldr scott/tiger control=/home/ramesh/sqlldr-when.ctl Commit point reached - logical record count 5
As you see from the above output, it still says “logical record count 5”, but you should check the log files to see how many records were loaded, and how many records were discarded because it didn’t match the when condition.
The following from the log file shows that 5 records were read, and 2 of them were discarded as it didn’t match the when condition.
Discard File: none specified Total logical records read: 5 Total logical records discarded: 2
Verify that only the selective records were loaded into the table.
SQL> select * from employee;
ID NAME DEPT SALARY HIREDON

My name is Ramesh Natarajan. I will be posting instruction guides, how-to, troubleshooting tips and tricks on Linux, database, hardware, security and web. My focus is to write articles that will either teach you or help you resolve a problem. Read more about
Comments on this entry are closed.
I will be reading Oracle & PL/SQL next month.
Thanks for the article.
Great Post.. thanks for the examples 🙂
This is Nice….
We Need More Examples Like This……..
Thanks……….
excellent article i love your all post
thanks for all
Really awesome!!!! Appreciate ….
Question. My data file has 30 columns. The table has 38 columns. I need to pick only 3 columns from the data file (5th, 10th and 25th column) and load into the table (column 3rd, 9th and 16th column of table). How do I do this? Any Idea?
@Ramesh: Awesome article. Very simple language and understandable examples. Thanks for sharing. I have few questions for you:
1) In example 8, terminated clause is not mentioned, because fields are terminated by space. So by derfault spaces are considered as delimiters?
2) I read that Badfile can be explicitly specified using clause ‘BADFILE filename.extension’. But on some links I see it mentioned as ‘BAD=file.extension’
Which one is correct.
3) On link below:
http://stackoverflow.com/questions/8039012/disable-bad-discard-file-log-on-sql-loader
it is mentioned that, bad file can be diabled by setting BAD=NUL (in windows) or redirecting bad output to /dev/null (on linux). Is it possible? I do not see any references on oracle site for this.
@Manjula:
Ramesh has explained answer to your question in example 8.
Hello Ramesh,
Regarding disabling bad files i confirmed. In windows it can be done using: BADFILE NUL
And in linux it can be done using: BADFILE /dev/null
Hi Ramesh,
This is simply superb 😀
I need your help in loading the single file where the scenario quite clumsy for me:
The data file sale_exec.dat:
_____________________________________________
CUST_TYPE | DATE | AMT | DISCOUNT_AMT
X |20120101 | 200 | 20
X |20120101 | 400 | 30
Y |20120303 | 300 |40
Z |20120303 | 20 |50
_______________________________________________
The table structure is :
TABLE SALES
{
VENDORID NUMBER,
REPORT_DATE DATE,
LOAD_DATE DATE,
AMOUNT NUMBER
}
Scenario:
1. The data within the file sales_exec.dat has to be loaded into the table SALES
2. When CUST_TYP is X the Vendorid should be 1 , when Y it should load vendor ID with 2 and similarly when it is Z then Vendor ID should be 3
3. When the CUST_TYP is X and Y I need to load the records with the AMT in the data file into the SALES table AMOUNT field
4. When the CUST_TYP is Z then I need to load the records with the DISCOUNT_AMT in the data file into the SALES table AMOUNT FIELD
The table data from the Data file after load should look like below:
_____________________________________________
VENDORID | REPORT_DATE| AMOUNT
1 |20120101 | 200
1 |20120101 | 400
2 |20120303 | 300
3 |20120303 | 50
_______________________________________________
Please let me know how should I proceed further and what should be my cntl file.
Thanks in advance!
Regards,
Rohit
@Rohit,
This is not possible using SQL loaders. Because data type of VendorId is numeric and from infile you are getting characters. You have two approches here:
1) Either you process your infile first and replace X by 1, y by 2, z by 3. Then use SQL loader using when condition to check what vendoe id is it and amount column should take what value. OR
2) You need to use external tables and SQL functions in this scenario.
Refer:

Thank You Prithviraj .
We can do it using a control file this way.
I tried using the boundfiller,decodes and my CONTROL file will look like this:
INFILE=’sale_exec.dat’
APPEND
PRESERVE BLANKS
INTO TABLE SALES
FIELDS TERMINATED BY ‘,’ OPTIONALLY ENCLOSED BY ‘”‘ TRAILING NULLCOLS
(
c1 BOUNDFILLER,
REPORT_DATE,
c2 BOUNDFILLER,
c3 BOUNDFILLER,
VENDORID “to_number(DECODE(:c1,’X’,1,’Y’,2,3))”,
AMOUNT “to_number(DECODE(:c1,’Z’,c3,c2))”
)
This worked good for me.
Thank You once again.
Regards,
Rohit K
Hi Ramesh,
this is a very good writeup! Is there anything more advanced which SQLLDR can handle? Would be great if you could write something on this too.
HI all,
I wanted too load mulitple files into the same tables from different ctl files for test work. The problem is i need to be able too identify the different files loaded in de database.
For example :
file1.ctl needs to be de name in de database under for example column ‘filename’
file2.ctl needs to be de name in de database under for example column ‘filename’
VENDORID | REPORT_DATE| AMOUNT|Filename
1 |20120101 | 200 |file1.ctl
1 |20120101 | 400 |file2.ctl
Anyone knows how i can get this accomplished.
Kind regards,
Jurgen
Thanks for giving such valuable examples. Could you please give one example of control file to upload data in a file and then call a procedure to implement some logic and populate main table.
Very nice article.
Better understandable format. Explained well.
We need more examples like this.
Hi All,
I have a flatfile(notepad), which has data not in order, fields separated by space, that too not orderly separated. Between fields there is space, but not ordered one. like
consultant name vendor details email contact end client
David Raj jason Roy jasonroy@example.com (010) 110-1101 CAAM
above line, you can notice that there is no specified space between fields. i have nearly 7000 rows of data in notepad. I tried using field terminated by space but, it has taken the entire row of data from notepad as a single column data in table, remaining fields in table are empty.
In this case is there any kind of solution/control file format to load the data into tables. It would be great if anyone can solve my problem.
Thanks
souji

Greate article, thank you for sharing.
After executing this below command from oracle forms6 sqlldr80 does not resume back to form, it remains there cursor blinking after Commit point reached – logical record count 10. It started from last week only, never happend before… dont know what made to act like this?
sqlldr80 USERID=kaps/kaps@kaporacle CONTROL=I:\load.CTL LOG=I:\LoadLOG.LOG BAD=I:\LoadBAD.BAD
Is there any way to terminate the control file i mean to exit sqlldr and come back to DOS prompt? It is not coming out of sqlldr mode… but inserting data is done perfectly.. any help appreciated…
Very Nice !!!!!! BUT how to load default value to a field.
I have a different scenario. I have a table with 5 columns, c1, c2, c3, c4, c5 and a csv file has 6 columns, a,c1,c2,c3,c4,c5. I would like to load c1 to c5 columns data from the csv file to c1 to c5 columns in the table. Can we skip columns any columns from csv or can we map csv columns to table columns in the loader control file ?
I got it. Keeping FILLER keyword to the right of column name would skip the column:
For e.g.:
OPTIONS (SKIP=1)
LOAD DATA
INFILE ‘source.csv’
BADFILE ‘source.csv.bad’
DISCARDFILE ‘source.csv.dsc’
APPEND
INTO TABLE tab_name
FIELDS TERMINATED BY ‘,’ OPTIONALLY ENCLOSED BY ‘”‘
TRAILING NULLCOLS
( a FILLER
,c1
,c2
,c3
,c4
,c5
)

plase help me
Thanks..it easy to understand to New guys also….
U forgot to mension insert command before into.
Good Example on SQL Loader.
i have db background but my knowledge about sql loader is not that great.
my question is if i have data file.. say the order of coumns in
loader file is val1,val2,val3,val4… so on
what should be the order/sequence of the columns in my control file..
should it be val1,val2,val3,val4..??
what if i have a column as filler,…
finally how does the order of columns in table comes in to play..
thanks in advance, i know these are very basic questions but.. i need
them for my current job requires requires dealing with lot of data loads.
Thank you! I was able to figure out a few things that I was missing but need one more thing that I’m surprised isn’t mentioned here.
I would love to see an example of how to append a wildcard onto an INFILE statement. Let’s say that you have a filename that is automatically generated from another source for EACH day. Coding the parms for the date are simple, and ideally there should only be one file for the day so the last part of the filename is a timestamp that would be impossible to determine since it’s a 3rd-party source.
For example, today’s filename is: AUTOLOAD2014M141224_100038012.csv
On the CTL file, the INFILE is set as…
INFILE ‘L:\MyFolder\MySubFolder\IMPORT\AUTOLOAD\AUTOLOAD2014M\%getMyParm%*.csv’
the BAT file has this to build getMyParm up to the day of the month
SET YEAR=%DATE:~10,4%
SET MONTH=%DATE:~4,2%
SET DAY=%DATE:~7,2%
SET DASH=_
SET WILD=*.csv
SET getMyParm=AUTOLOAD%YEAR%M14%MONTH%%DAY%%DASH%%WILD%
–SQLLDR command is:
SQLLDR USERID=CREPORTS/CRPTSPWX@XYZ.COM:1234/MyDaySchema CONTROL=DAILYLOADCONTROL.CTL LOG=DAILYLOAD_HISTORY.LOG
At manual execution, I receive this…

SQL*Loader-554: error opening file
SQL*Loader-509: System error: The device does not recognize the command.
SQL*Loader-2026: the load was aborted because SQL Loader cannot continue.
I would think it would recognize a * per other CMD forums I checked. I even tried hardcoding the *.csv on the INFILE within the CTL but that returns the same result and the same error.
Any ideas as to what it’s seeing and interpretting?
Thank you
