Hello,

I have multiple csv files in a directory. This directory will be updated with new csv-files. I need to load all csv files with sqloader in 1 table. So all the files have the same columns only different data.

This is how my control file looks:

load data 
infile 'test.csv' "str '\r\n'"
append
into table TABLE1
fields terminated by ','
OPTIONALLY ENCLOSED BY '"' AND '"'
trailing nullcols
           ( COLUMN1 CHAR(4000),
             COLUMN2 CHAR(4000),
             COLUMN3 CHAR(4000)
           )       


And here is my batch file (used generic names for demostration purposes):

@echo off
sqlldr 'username/pw@dbip' 
CONTROL=testSmall.ctl LOG=C:\Users\Desktop\sqloader_files\test.log 
BAD=C:\Users\Desktop\sqloader_files\test.bad skip=1 
pause

This works fine whith one csv file, however i need to iterate through all files and call sql loader for each file.When i am finished, i just move all the csv files in a different folder and then execute the batch file again when new files come along. Do you think this is a good solution?

I need to do this in Windows, however i am not familiar with any scripting language. Is it possible to do this only with a for loop in cmd? Or do we need to write a script with powershell or some other scripting language in windows? Would appreciate if someone could help me

thx in advanve

Everything you want to do can be done from OS command line; so OS script is most direct solution.
Solution can easily be implemented in PERL; too.

do the directory & files reside on DB Server itself?

What is Oracle version to 4 decimal places?

Yeah the files are on the DB server.
Oracle Version 12.1.0.2

You can use, for instance, something like:
for %f in (C:\Users\Desktop\sqloader_files\*.txt) do \
sqlldr 'username/pw@dbip' DATA=%f \
CONTROL=testSmall.ctl LOG=C:\Users\Desktop\sqloader_files\test.log  \
BAD=C:\Users\Desktop\sqloader_files\test.bad skip=1 
And you remove the "infile" line of your control file.

Thanks, I will try it tomorrow, since I am not on my machine now.
Didn't know that you can pass a parameter with DATA to the control file
In the end I need to write some cmd-commands to copy all the files from the
existing directory and make a new folder with a timestamp. Because the
main directory will always be updated with new csv-files and I dont want to
import the same files. Do you think this is a good solution? And I think
this should also be no problem just by using cmd-commands. Sry to ask you
that but i am not familiar with windows

I have tried the solution above, but it doesnt work.
When I execute my batch-file it opens and closes automatically, even if
i have a pause command

Here is my ctl-file (I deleted the infile-statement, since I pass it as paramater when i execute the batch-file):

load data 
append
into table SAMP_TABLE
fields terminated by ','
OPTIONALLY ENCLOSED BY '"' AND '"'
trailing nullcols
           ( COLUMN1 CHAR(4000),
             COLUMN2 CHAR(4000),
             COLUMN3 CHAR(4000)
           )


And here is my batch-file:

@echo off
for %f in (*.csv) do \
sqlldr 'username/pw@dbip' DATA=%f \ CONTROL=mycontrolfile.ctl 
LOG=C:\Users\test\test.log \
BAD=C:\Users\test\test.bad skip=1 
pause

the batch-file, control-file and the csv-file are in the same directory

Run the batch file from a command prompt and copy and paste the output for us to see it.

I have solver the problem. This is the solution;

@echo off
for %%F in ("C:\Users\test\*.csv") do (
IF NOT EXIST C:...\archive md C:..\archive
sqlldr username/pw@dbip CONTROL='C:\Users\test\test2.ctl' LOG='C:\Users\test\TEST.log' "DATA=%%F"
move %%F C: ..\archive
)


this is my solution. I only create 1 folder...it would be nice to create different folder with a timestamp after each import of all csv-files (for example today I import 10 csv-files..then i create a folder with the actual date and move all csv-files there, then the next day i do the same if knew csv-files come along)..do you know how to do that? is it possible in cmd?

You can use %DATE% and %TIME% pseudo-variables:
E:\>echo %date%
11/07/2017

E:\>echo %time%
19:13:30,70
Check the output in your case, it depends on country and Windows version
You can use shell extension to format these variables:
C:\>echo %date%
11/07/2017

C:\>echo %date:~6,4%%date:~3,2%%date:~0,2%
20170711
Use "help set" or search on the web for the details on these commands.

Thx for the answers, here is my solution:

This is my control-file:
load data 
append
into table SAMP_TABLE
fields terminated by ','
OPTIONALLY ENCLOSED BY '"' AND '"'
trailing nullcols
           ( 
             INSERT_DATE EXPRESSION "current_timestamp(3)",
             FILE_NAME CHAR(4000),
             COLUMN1 CHAR(4000)
             COLUMN2 CHAR(4000)
           )

And this is my batch-file (I need to do it in a windows-machine):

@echo off
IF NOT EXIST C:\Users\test\csvFiles
IF NOT EXIST C:\Users\test\logfiles
for %%F in ("C:\Users\test\*.csv") do (
SET tmpFile=%%F
SET newFile=%tmpFile:~0,-3%.log
sqlldr db_user/db_pw@db_ip CONTROL='C:\Users\test.ctl' LOG='C:\Users\logfiles\%newFile%' "DATA=%%F" skip=1
move %%F C:\Users\test\csvFiles
)
pause
What it does is, it creates 2 folders at the beginning: "csvFiles" (to move the csv-file to this folder after it is loaded) and "logfiles" (to move the created log-file).
(With DATA=%%F i can pass the csv-file to the control-file)
You can see that the first 2 columns on my control-file are "INSERT DATE" which inserts the current_timestamp and "FILE_NAME".

Now my problem now is that I dont know how to pass the file-name of the csv-file(which will be loaded) to the control-file. I want for each import csv-file to insert the file-name of this csv-file into this column. I searched for some solutions but some of them are in UNIX, however I need to do it in Windows.

I would appreciate if someone could help me, since I am not very familiar with batch-scripting or scripting in general.

You can generate the control file on the fly like (here I used the date where you have to use %F%):
E:\>echo load data                                                   >test.ctl
E:\>echo append                                                      >>test.ctl
E:\>echo into table SAMP_TABLE                                       >>test.ctl
E:\>echo fields terminated by ','                                    >>test.ctl
E:\>echo OPTIONALLY ENCLOSED BY '"' AND '"'                          >>test.ctl
E:\>echo trailing nullcols                                           >>test.ctl
E:\>echo            (                                                >>test.ctl
E:\>echo              INSERT_DATE EXPRESSION "current_timestamp(3)", >>test.ctl
E:\>echo              FILE_NAME constant "%DATE%",                   >>test.ctl
E:\>echo              COLUMN1 CHAR(4000)                             >>test.ctl
E:\>echo              COLUMN2 CHAR(4000)                             >>test.ctl
E:\>echo            )                                                >>test.ctl
E:\>type test.ctl
load data
append
into table SAMP_TABLE
fields terminated by ','
OPTIONALLY ENCLOSED BY '"' AND '"'
trailing nullcols
           (
             INSERT_DATE EXPRESSION "current_timestamp(3)",
             FILE_NAME constant "11/07/2017",
             COLUMN1 CHAR(4000)
             COLUMN2 CHAR(4000)
           )

This is an interesting approach, never thought of that.
However I am not very familiar with the cmd-commands...
can u elaborate on your solution because I dont understand it...how do I write your code in the batch-file...i am a bit confused
I need to insert your after this line in my batch-file right?:

for %%F in ("C:\Users\test\*.csv") do (

The file will be automatically created? Can I then just afterwards execute the sqlldr command?

I edited my answer before. I have an additional question.
But the problem is now that it will create multiple ctl-files (because we are in a for-loop) right?
The file will be automatically created in the loop? Can I then just afterwards execute the sqlldr command?

And another maybe very noob question. I dont need to use the "echo" command right?
Sry for asking but I dont work on windows...but echo means it just prints it out on the console right?

No, only one, always the same name.

Quote:

Yes, you need it.
echo ... >file
means create or empty a file and put in it what's inside "echo"
echo ... >>file
means append to the file what's inside "echo".

It is the same thing in Unix (any flavor), Linux, VMS... on what do you work?

Thx for your help, I really appreciate it. (I am a junior java dev without scripting skills or very low)

Just an additional question. If I want to load the data into 2 different tables.
So I have 1 csv-file and 2 tables.

1-Table has the following columns:
----------------------------------
FILE_NAME(PK)
INSERT_DATE

2-Table has the following columns:
----------------------------------
PK(sequence)
FILE-NAME(FK)
COLUMN1
COLUMN2


The first and second table would have a 1-n relationship.
I just want to avoid loading the same csv-file (all csv-file are unique by their name)

I would do it like this after your input:


@echo off
IF NOT EXIST C:\Users\test\csvFiles
IF NOT EXIST C:\Users\test\logfiles
for %%F in ("C:\Users\test\*.csv") do (

echo load data                                                   >test1.ctl
echo append                                                      >>test1.ctl
echo into table SAMP_TABLE                                       >>test1.ctl
echo fields terminated by ','                                    >>test1.ctl
echo OPTIONALLY ENCLOSED BY '"' AND '"'                          >>test1.ctl
echo trailing nullcols                                           >>test1.ctl
echo            (                                                >>test1.ctl
echo              FILE_NAME constant "%FF%",                     >>test1.ctl
echo              INSERT_DATE EXPRESSION "current_timestamp(3)", >>test1.ctl
echo                                                             >>test1.ctl
echo            )  
SET tmpFile=%%F
SET newFile=%tmpFile:~0,-3%.log
sqlldr db_user/db_pw@db_ip CONTROL='C:\Users\test1.ctl' LOG='C:\Users\logfiles\%newFile%' "DATA=%%F" skip=1
move %%F C:\Users\test\csvFiles

echo load data                                                   >test2.ctl
echo append                                                      >>test2.ctl
echo into table SAMP_TABLE                                       >>test2.ctl
echo fields terminated by ','                                    >>test2.ctl
echo OPTIONALLY ENCLOSED BY '"' AND '"'                          >>test2.ctl
echo trailing nullcols                                           >>test2.ctl
echo            (                                                >>test2.ctl
echo              FILE_NAME constant "%FF%",                     >>test2.ctl
echo              COLUMN1 CHAR(4000),                            >>test2.ctl
echo              OLUMN2 CHAR(4000)                              >>test2.ctl
echo            )  
SET tmpFile=%%F
SET newFile=%tmpFile:~0,-3%.log
sqlldr db_user/db_pw@db_ip CONTROL='C:\Users\test2.ctl' LOG='C:\Users\logfiles\%newFile%' "DATA=%%F" skip=1
move %%F C:\Users\test\csvFiles
)
pause

What I am trying to achieve is that, first it will import into the first table and then if the file-name is already present in the table (it means that i has been alread imported)
then it should stop. Maybe I also need to create different log-file names for both imports

It is not %FF% but %%F in your case (must be tested).
You can test the return code or the content of log file or bad file.

Maybe you should investigate in a higher level language like Perl or WSH (Windows Script Host) or Python or Ruby... if you want to do more complex things.

Yeah, you are right, however unfortenately i dont have the time to invest learning a new language...but as far as i know it is possible with sqloader to insert into two different tables.

i need to create the ctl-files on the fly it makes things more complicated..i just want to make sure to add the file name and date into a seperate table and make the file name a pk..so when the file with the same file name is imported the second time than it wont work because i would have an unique key constraint error

It appears you are currently learning at the same time SQL*Loader and DOS scripting. Smile

Yes, there are many examples in our "Utilities" (sub-)forum, use the "Search" link at top of the page adn search for something like "load file into multiple tables".

Set "errors=1" on your sqlldr command line but it may be another error.

I am trying to create the control-file on the fly but it is not working.
Here is my batch-file ( I have csv-files in my directory so the loop should work):

IF NOT EXIST C:\Users\test\logfiles

SET newFile=%tmpFile:~0,-3%.log
sqlldr db_user/db_pw@db_ip CONTROL='C:\Users\test1.ctl' LOG='C:\Users\logfiles\%newFile%' "DATA=%%F" skip=1
move %%F C:\Users\test\csvFiles

)
pause

It works only without a for-loop, i dont know why...

"it is not working" gives no idea what is not working and what it means.

Sry you are right...The control-file won't be created...
After I execute the bat-file it opens and closes automatically.
I think I have solved it partly(will post the solution if it is complete).

Now the problem is that after the control-file is created in the loop..
it cannot create it again because i get the error message that the file
is locked by another process..which means by my own bat-script..

The original message is="The process cannot access the file because it is being used by another process"


do you know
how to solve this issue?

The first "echo" line must have only 1 > not 2.

And the whole "do" must not end with >>test1.ctl

Sry this was a type. Here is my file and I think it is correct (The for-loop ends at the end of the file before the pause)
(Just ignore the different names for the columns..this is just for demonstration purposes)

for %%F in ("C:\test\*.csv") do (
	echo load data                                                   >test1.ctl
	echo append                                                      >>test1.ctl
	echo into table TAB_NAME                                           >>test1.ctl
	echo fields terminated by ','                                    >>test1.ctl
	echo OPTIONALLY ENCLOSED BY '"' AND '"'                          >>test1.ctl
	echo trailing nullcols                                           >>test1.ctl
	echo            (                                                >>test1.ctl
	echo               COLUMN1 CHAR(4000),                           >>test1.ctl
	echo               COLUMN2 CHAR(4000), 				 >>test1.ctl
	echo               COLUMN3 CHAR(4000)				 >>test1.ctl
	echo            )  						 >>test1.ctl
SET tmpFile=%%F
SET newFile=%tmpFile:~0,-3%.log
sqlldr db_user/db_pw@db_ip CONTROL='C:\test\test1.ctl' LOG='C:\test\logs\%newFile%' "DATA=%%F" skip=1
)

I have solved the issue...the mistake was because I had a wrong db-ip (I thought I need to check my loop and so on)
But now the other problem is that the code above only created the control file with this content:

      COLUMN1 CHAR(4000
              COLUMN2 CHAR(4000), 							 
              COLUMN3 CHAR(4000)							     
           )  											     

So the parts at the beginning are missing. Do you know maybe why?

I am stuck, I don't know what to do next.
This is my batch-file:

@echo off
for %%i in ("C:\Users\test\*.csv") do (
SET tmpFile=%%~ni
echo load data                                                      >test1.ctl
echo INFILE 'test1.ctl'											    >>test1.ctl
echo into table TABLE_NAME	                                    >>test1.ctl
echo append                                                         >>test1.ctl
echo fields terminated by ','                                       >>test1.ctl
echo OPTIONALLY ENCLOSED BY '"' AND '"'                             >>test1.ctl
echo trailing nullcols                                              >>test1.ctl
echo            (                                                   >>test1.ctl
echo              	 COLUMN1 CHAR(4000),		                        >>test1.ctl
echo                 COLUMN2 CHAR(4000), 							>>test1.ctl
echo                 COLUMN3 CHAR(4000), 								>>test1.ctl
echo                 FILE_NAME  %tmpFile%             				>>test1.ctl
echo            )                                                   >>test1.ctl
sqlldr db_user/db_pw CONTROL='C:\test\test1.ctl' LOG='C:\Users\test\mylog.log' skip=1
) 
pause

It creates the control-file, however only with this content (the other part is missing):

  COLUMN1 CHAR(4000
              COLUMN2 CHAR(4000), 							 
              COLUMN3 CHAR(4000),
	      FILE_NAME test					     
           )  

And second I get the error in the cmd: The process cannot access the file because it is being used by another process.

So here is the solution:

@echo off
for %%i in ("C:\Users\test\*.csv") do (
    > "test1.ctl" (
        echo load data
        echo INFILE 'test1.ctl'
        echo into table TABLE_NAME
        echo append
        echo fields terminated by ','
        echo OPTIONALLY ENCLOSED BY '"' AND '"'
        echo trailing nullcols
        echo            ^(
        echo                 COLUMN1 CHAR^(4000^),
        echo                 COLUMN2 CHAR^(4000^),
        echo                 COLUMN3 CHAR^(4000^),
        echo                 FILE_NAME  %%~ni
        echo            ^)
    )
    sqlldr db_user/db_pw CONTROL='C:\test\test1.ctl' LOG='C:\Users\test\mylog.log' skip=1
)
pause

Thanks for the feedback and solution.
Are you sure the loader step works correctly?
It seems to me the generated control file is not correct.

Yeah it works, I did some tests before posting the solution.
Thx very much for helping me
