How to use Conditional statements in SQL Loader control file
Hi,
I am using sql loader to load a flat file to the table. I am using control file for this purpose as show below:
LOAD
INTO TABLE store_shrink
TRUNCATE
FIELDS TERMINATED BY " "
TRAILING NULLCOLS
SITE_ID char,
ST_SHRINK char,
ST_REVENUE char,
SHRINK_PR char ":ST_SHRINK/:ST_REVENUE"
My question is this. If in the flat file the value of 'ST_REVENUE' is '0', then I want 'SHRINK_PR' to be '0' as well, and skip the calculation (:st_shrink/:st_revenue).
How to achieve this with the conditional statement or using any Oracle function?
Any help or suggestion is greatly appreciated.
Thanks in advance.
Hi there,
I tried the following in my above query and it doesn't work somehow. Anyone has an idea? I have been on internet throughout but to no avail. Please help:
LOAD
INTO TABLE store_shrink
TRUNCATE
FIELDS TERMINATED BY " "
TRAILING NULLCOLS
SITE_ID char,
ST_SHRINK char,
ST_REVENUE char,
SHRINK_PR char "case (when :st_revenue<>'0.00' then :SHRINK_PR=:ST_SHRINK/:ST_REVENUE else :SHRINK_PR='0.00') end"
)

Use of WHEN in SQL Loader Control File
Does anyone know of a way, using the CTL file below, to NOT LOAD (i.e. discard) any record where field G is null -OR- substr(G,1,3)='CON'+ (the first 3 characters of field G are "CON")?
The WHEN clause seems very limited in what it can test and all my attempts to use a compound condition, much less the SUBSTR function, have failed. The documentation indicates that only very simple conditions can be specified.
(Oracle 10g, Unix)
Thanks

)Hello MTM.
The WHEN clause in SQL*Loader, despite what you might read, doesn't seem to evaluate the value of the column you specify after SQL clauses are processed. Therefore, the only way you can guarantee to NOT LOAD a record is by using a function to raise an application error when the column data meets your criteria. You'll need to do some basic comparisons between bad data and discarded data in the bad data file to isolate these.
You can still discard the null data using (replace ne with greater and less than)WHEN (g ne '')Hope this helps,

Using constant values in SQL Loader control file
Hi,
I have a requirement where I need to migrate the data of 6 tables from MS Access into Oracle data base. I have written SQL Loader scripts so that I can create CSV files based on MS Access data and then migrate into Oracle. But in Oracle tables we have 4 common columns like Create_By, Created_Date,Updated_By and Update_Date, and those fields should be taken care by system. So, basically system should update login user ID and sysdate values in respective columns. My question here is, I do not have above mentioned common columns in MS Access tables. So, can I hard code those values in control file by saying
Created_By CONSTANT user,
Create_Date CONSTANT TO_CHAR(SYSDATE,'MM/DD/YYYY HH24:MI:SS'),
Updated_By CONSTANT user,
Updated_Date CONSTANT TO_CHAR(SYSDATE,'MM/DD/YYYY HH24:MI:SS')
Please let me know your valuable suggestions.You do it without it constant

Parameters / Variables in SQL Loader Control File
Here's my problem, I have created SQL Loader control file (ctl) to load a file of employees. This loader program is registered in Oracle Applications. What I want is to pass a parameter derived from the profile like the user name of the one who executed the loader program and pass it to the loader program so that the user name info is included in the loading
example
input data
123456,John,Smith
654321,Jane,Doe
loaded data
123456,John,Smith,03-JUL-2009,USER13
654321,Jane,Doe,03-JUL-2009,USER13
the sysdate is easy because it can be defined in the column but what I really want to achieve is a parameter passed to the ctl file.
Thanks in advance.Dear user!
Please have a look at this thread.
{thread:id=915277}
In the last three posts I explain how to use a shellscript with AWK and SED to pass parameters to a controlfile.
Please feel free to post again if you have some questions regarding my explanatory notes.
Yours sincerely

Define variable in SQL Loader Control File
Hi,
I have an input file where the first line is the header record, followed by the detail records. For the processing, I do not need to store the fields of the header record but I need a date field from this header record and store in as part of the detail record in an oracle record row.
Is it possible to define a variable within the sql loader control file to store the value that I need in memory then use it when I do the sql insert by the sql loader?
Thanks for any advice.Not sure that you can. But if your on unix/linux/mac its easy enough to write a shell script to populates the variables in a template file that you can then use as the ctl file. The perl template toolkit could be an option for that as well

Add "Trailing Nullcolls" to sql loader control files generated by OWB
Hi gurus,
I've got a problem loading data with SQL Loader. I need to add the parameter "trailing nullcols" into the SQL Loader control file generated by OWB. I don't want to do this by saving the skript on my hard disk and run it manually, so any ideas where I can put this parameter? I am using OWB 10.1 on a windows 2000 machine.
Thanks
StephanHi,
I found the solution to problem.
1; Select the mapping where you map your source flat file to a table.
2; Right click on the mapping and select "configure"
3; Go Sources and Targets -> YOUR_TABLE_NAME -> SQL*Loader Parameters
4; Set Trailing Nullcols = true :-)
Thank you to anyone looking at this problem.
Greetings

Importing already-made SQL*Loader control files in OWB 10g
Hi all,
Suppose that I have a certain amount of already hand-made SQL*Loader control files, say 50 or so.
Each of these control files have a variable quantity of fields.
I feel really lazy, so I would like to know if it is possible to import directly these control files instead of re-typing them in the design center. That would save me a lot of time.
Thanks !
BurgyHi Burgy
One option is to use the sqlloader option to generate an external table from the SQLLoader control file (search for generate_only in the sqlloader documentation). If you define the external table in the database you can reverse engineer this into OWB.
Cheers

SQL Loader Control File use of integer(n)
Dear Gentlemen,
I have an "ascii" file where some fields are binary of 2, 4 and 8 bytes. This file has to be loaded to oracle (8.1.7) Table using SQL Loader. According to SQL Loader documentation, for this case I must use as a field type: integer(n), where in my particular environment (Intel Windows), n may be 2, 4 or 8 according to the length of the field. Although I do not need to specify for integer(4); but, for integer(2) and integer(8), I need to specify it to get the rigth values. In the case of integer(2), it can be replaced by smallint; however for integer(8), I have to specify the number (8), and this form is not accepted as a sintactically correct statement by SQL Loader. Therefore I cannot load the correct data.
Could you please give some advice?.
Best regards,
Julio Porcel.Hi!
If it's not possible to implement through control file, load your data into some temporary table and then use power of SQL to do whatever you want with them.

Sql loader control file path........
Hello all,
I am running the below query through sql loader from client machine.....
saved the below query in loader.ctl file, which I kept in "D:\loader.ctl" path....
options (skip=1)
load data
infile 'D:\flat.txt'
into table GL_INTERFACE
fields terminated by "," optionally enclosed by '"'
*( STATUS, LEDGER_ID, USER_JE_SOURCE_NAME, USER_JE_CATEGORY_NAME, ACCOUNTING_DATE, CURRENCY_CODE, DATE_CREATED, CREATED_BY,*
SEGMENT1, SEGMENT2, SEGMENT3, SEGMENT4, SEGMENT5, ACTUAL_FLAG, ENTERED_DR, ENTERED_CR, GROUP_ID )
Now my doubt is, to execute the above I have to run the below command in sql loader....
sqlldr USERID=apps/apps CONTROL=loader.ctl
In the control file we have given the path for the data file, but * How the command (SQLLDR) identify the path of control file.?*
Do I need to give or......?
Is it possible to run the above loader program in client machine? or we have to run only server alone.....
Please clarify my doubt.
Thanks and Regards,
MuthuHi,
The good practice is, If you are using oracle apps then register a concurrent program of type sql*loader
put yor ctl file in $<ANY_TOP>/bin. Run Concurrent program to load the data.
I am just givng you the hints, You search on google u will get multiple ways to do the same things.
There are lots of ways like using of external table,UTL_FILE or Shell Script to do the same thing.
Thanks,

How to skip footer record in SQL*Loader input file
I have am using SQL*Loader in a batch import process.
The input files to SQL*Loader have a header record and footer record - always the 1st and last records in the file.
I need SQL*Loader to ignore these two records in every file when performing the import. I can easily ignore the header by using the SKIP function.
Does anybody know how to ignore the last record (footer) in an input file??
I do not want to physically pre-strip the footer since the business want all data files to have the header and footer records.Thanks - how do I use the when clause to specify the last line of the input file?
I am presuming it requires me to have a unique identifier at a given position on that last line. If I don't have such an identifier can I still use your solution?
Cheers Why not putting an idetifier at the end of your input file: echo "This_is_the_End" >> input_file ? -
SQL Loader Control file help!!!
Hi All,
I was in the process of writing a control file for sql loader for an activity i am performing and would appreciate inputs from you all.
I have a table patient containing 44 columns, i have a column 'SEC_LANG_NAME' in which i have to insert data from a excel file.
The excel file contains 3 columns, PATIENT_ID, NAME,SEC_LANG_NAME, i just want to load the values present in 'SEC_LANG_NAME' column in excel file into the 'SEC_LANG_NAME' coulmn in the patient table using sqlloader and the condition is that PATIENT_ID in excel file should be equal to PATIENT_ID in the patient table.
as a first step i am converting this excel into a csv file, and then will shoot the sqlldr once i am done with control file, can someone please help me with the format of control file for this activity.
thanks in advance,
regards,
Edited by: user10243788 on Jan 3, 2010 12:09 AMHello user10243788.
It appears that your intent is to load data into an existing table that contains the key data and is only lacking a column of information. SQL*Loader itself is not built to do this; what it can do is load records to tables. You will have to use a two-step approach similar to what Srini has suggested. 1) If your process is able to be run local to the database server, an external table is a great option. If your process is instead run remote to the database server, SQL*Loader will allow you to load your data file to a table. 2) You will need to run a process to update the PATIENT table.
Here is a start of a control file based on the details that you've providedLOAD DATA
REPLACE
INTO patient_enhance
FIELDS TERMINATED BY ","
( patient_id
, name FILLER
, sec_lang_name)Hope this helps,
Luke

Function for column validation in SQl Loader control file.
Hello Gurus,
We have an requirement to create a function to validate all date and number columns in control file, and return 0/1 accordingly to valid_column which is last column . I have developed the function which accepts the number and date type columns as parameter and return Y/N. My question is, is there any way so that the function could be created without passing any parameter to it?
If yes, then how to call the function in control file?
I have been searching since a while on Google to find out any solution but could find out.
