Sql Loader Skipping fields in a csv file

Hi,
I have a comma delimited flat file with more fields than I need and am curious if there is a loader technique
to skip some of the fields. E.g. Given a three field file, I want to associate the 1st and 3rd fields with table columns and ignore the 2nd field.
Sorry if this seems simple. This is my first time with loader and nothing in the Doc. Jumps out at me.
Obviously I can massage the file prior to loader with sed, awk, perl. I'm really just curious if I can do it in loader itself.
Thanks
Ken

You can use the FILLER keyword.

Using SQL LOADER in Oracle to import CSV file

I'm pretty new to databases and programming. Im not very good with the computer lingo so stick with me. I have a csv file that I'm trying to load into my oracle database. It contains account information such as name telephone number service dates ect. I've installed Oracle 11g Release 2. This is what I've done so far step by step..
1) Ran SQL Loader
I created a new table with the columns that I needed. For example
create table Billing ( TAP_ID char(10), ACCT_NUM char(10), MR_ID char(10), HOUSE_NUM char(10), STREET char(30), NAME char(50)
2) It prompted me that the Table was created. Next I created a control file for the data in notepad which was located in the same directory as my Billing table and has a .ctl extension. GIS.csv is the file im getting the data from and is also in the same directory and named it Billing.ctl, which looked like so..
load data
infile GIS.csv
into table Billing
fields terminated by ','
(TAP_ID, ACCT_NUM, MR_ID, HOUSE_NUM, STREET, NAME)
3) Run sqlldr from command line to use the control file
sqlldr myusername/mypassword Billing.ctl
This is where I am stuck. Ive seen video tutorials of exactly what I'm doing but I get this error:
SQL*Loader-350: Syntax error at line 1.
Expecting keyword LOAD, found "SERV TAP ID". "SERV TAP ID","ACCT NUMBER","MTR ID","SERV HOUSE","SERV STREET","SERV ^'
I dont understand why its coming up with that error. My billing.ctl has a load.
load data
infile GIS.csv
into table Billing
fields terminated by ','
(TAP_ID, ACCT_NUM, MTR_ID, SERV_HOUSE, SERV_STREET, SERV_TOWN, BIL_NAME, MTR_DATE_SET, BIL_PHONE, MTR_SIZE, BILL_CYCLE, MTR_RMT_ID)
Any thoughts?

I have thousands of records in this file and only 64 of them updated.How many record were in the table before and after? I doubt the difference is 64, unless you have exactly 64 rows but you said thousands. I believe you are probably misinterpreting the log file. can you share the full log file? As a test, create a empty table, use the same script and load same data file in this empty table. Once loading is complete, check if it has 64 rows or more. I believe what log file is saying, it is 'commiting after every 64 rows', not 'stopping after loading 64 rows'.
So, unless you show us the log file there is no way to be certain, feel free to mask confidential info, at-least top 15 and bottom 15 lines ?

SQL*Loader - Skipping columns in the source file.

Hi
I have a comma delimted source file with 4 columns. I however only want to load columns 2 and 3 into my table using SQL*Loader. This seems like something that should be fairly simple but I can't seem to find any doc or examples of this.
Any guidance would be appreciated.
Thanks
Dave

Hello Dave,
Here is a sample of what you'll need to have in your control fileLOAD DATA
APPEND
INTO TABLE <target_table>
FIELDS TERMINATED BY ','
( column_1 FILLER
, column_2
, column_3
, column_4 FILLER
)Hope this helps,
Luke

SQL*Loader: Skipping input files fields

There were several postings here addressing an issue of skipping fields from the input file when using SQL*Loader. Most suggestions were to use FILLER fields.
Is there any other way? My input file (over which I have no control) has literally hundreds of fields, most of them blanks. To write a control file with this many dummy fields will be difficult (I can write a perl script to do it, I know, I know...).
Thanks for any suggestions.

Hi, I think in your case the best tool for you use is pl/sql. Cause have function called Utl_file, there you have more control to do this type of load, and you can combine another functions.

Sql loader - skip record question

I am running Oracle 9 and using sql loader to import text file into table. Can sql loader skips the record which contain blank line or carriage return? Do I need to set up with options? Please advise me how. Thanks.

SQL*Loader-510: Physical record in data file (clob_table.ldr) is long

If I generate loader / Insert script from Raptor, it's not working for Clob columns.
I am getting error:
SQL*Loader-510: Physical record in data file (clob_table.ldr) is long
er than the maximum(1048576)
What's the solution?
Regards,

Hi,
Has the file been somehow changed by copying it between windows and unix? Ora file transfer done as binary or ASCII? The most common cause of your problem. Is if the end of line carriage return characters have been changed so they are no longer /n/r could this have happened? Can you open the file in a good editor or do an od command in unix to see what is actually present?

Trouble loading a large number of csv files

Hi All,
I am having an issue loading a large number of csv files into my LabVIEW program. I have attached a png of the simplified code for the load sequence alone.
What I want to do is load data from 5000 laser beam profiles, so 5000 csv files (68x68 elements), and then carry out some data analysis. However, the program will only ever load 2117 files, and I get no error messages. I have also tried, initially loading a single file, selecting a crop area - say 30x30 elements - and then loading the rest of the files cropped to these dimensions, but I still only get 2117 files.
Any thoughts would be much appreciated,

How many elements are in the array of paths (your size(s) indicator) ?
I suspect that the open file is somewhat limited to a certain number.
You could also select a certain folder and use 'List Folder' to get a list of files and load those.
Your data set is 170 MB, not really asthounising, however you should whatc your programming to prevent data-doublures.

Load data with SQL Loader link field between CSV file and Control File

Hi all,
in a SQL Loader control file, how do you specify link with field in CSV file and Control file?
E.g. if I wat to import the record in table TEST (col1, col2, col3) with data in csv file BUT in different position. How to do this?
FILE CSV (with variable position):
test1;prova;pippo;Ferrari;
xx;yy;hello;by;
In the table TEST i want that col1 = 'prova' (xx),
col2 = 'Ferrari' (yy)
col3 = default N
the others data in CSV file are ignored.
so:
load data
infile 'TEST.CSV'
into table TEST
fields terminated by ';'
col1 ?????,
col2 ?????,
col3 CONSTANT "N"
Thanks,
Attilio

With '?' mark i mean " How i can link this COL1 with column in csv file ? "

SQL*Loader Error Field in data file exceeds maximum length", version 8.1.6

Hi All,
I am trying to load a data file into a database table using SQL loader. I
received the data in an data file but I saved it as a pipe delimited
file.
When I run the SQL Loader command no records are loaded - looking at the log
file I get the following error:
Rejected - Error on table FARESDATA, column FANOTESIN.
Then I tried with substr and doesnt seem to work for values greater than 4000 chars, it only works if the field value is below 4000 chars (say doing a substr for first 3000 chars).
see the code--------
LOAD DATA
INFILE 'p.dat'
APPEND INTO TABLE PROSPECTUS
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
Fanotesin char(4000) "substr(:fanotesin,1,4000)"
We get the error ORA-01461: can bind a LONG value only for insert into a LONG column when using substr for 4000 chars.
Please help!
Thanks,
Rajesh

I believe the problem here is that the ORACLE database regards anything > 4000chs as a CLOB (or LONG). 4000 is the maximum length of a varchar2 field in the database, although of course you can declare larger values in PL/SQL. (Since the incoming data is > 4000 chs it is regarded as a LONG and you cannot therefore use SUBSTR on it)
I think that you must either truncate your data before loading or load into a table with the offending field as a CLOB (or LONG)
and then use PL/SQL to recreate it in a table with a varchar2(4000) which is otherwise identical. (You can select from a LONG into a varchar2(32000) for example and then truncate before writing out to the new table).

SQL Loader: specify position for pipe separated file

Hi,
I have a problem with sql loader. i need to load 5 columns in a table and my file only contains 3 fields (pipe separated file) i need to add a sequenced id and a loading date. When i try to run the below, the sequence and the sysdate is populated correctly, but column3 is inserted into column1. If i add my file two more null columns, then it works properly:
||column1|column2|column3
also if i put my variables in the end it also works, but i cannot restructure the table so this solution doesnt work. Do u have any idea how to specify positions in pipe separated files? i should load file in the below format:
column1|column2|column3
it onlz works properly if i add the two pipe in the beginning
my control file:
LOAD DATA
INFILE 'test201001.csv'
APPEND
INTO TABLE test_load
FIELDS TERMINATED BY '|'
id "seq.nextval",
sys_creation_date "sysdate",
column_1,
column_2,
column_3
Thanx your help in advance

Can you load the data "as is" into a work table, then use a PL/SQL program to process the work table correctly according to the data you have?

SQL Loader deletes data, after reporting a file not found error

I have several control files beginning:
LOAD DATA
INFILE <dataFile>
REPLACE INTO TABLE <tableName>
FIELDS TERMINATED BY '<separator>'
When running SQL Loader, in the case of one particular control file, if the file referenced does not exist, SQL Loader first reports that the file could not be found, but then proceeds to delete all the data in the table in which the import was meant to take place. The corresponding log file reveals that the file could not be found, but also states that 0 records were loaded and 0 records were skipped.
In the case of all other control files, if the file is not found, the log files simply report this exception but do not show any statisitcs about the number of records loaded/skipped nor does SQL Loader delete the data in any of the referenced tables. This is obviously the expected behaviour.
Why is SQL Loader deleting the data referenced by one particular control file, even though this file does not exist and the corresponding log file has correctly picked up on this?

in the ressource name box of your file model, when you push the search button ("...") do you see the file ?
Cause the problem can occur when you write directly the path without selectionning the file with the assistant.
Try this.
I think too that that you can't see the data by right clicking and selectionning View Data ?
Let me know the avancement...

SQL*LOADER에서 원하는 컬럼을 skip하여 load하는 방법

PURPOSE
================================
SQL*LOADER를 통해 data를 load하는 경우, 실제 data가 들어갈 테이블의 구조와 다른 data가 확보되는 경우가 있습니다. 이 경우 data를 다시 확보할 수 있다면 다행이지만, 불행히도 그렇지 못한 경우에는 어떻게 해야할 까요?
예를 들어 다음과 같은 형태의 data가 있는데...
aaa,bbb,ccc,ddd
eee,fff,ggg,hhh
실제로 table에는 2개의 column만이 존재하고, load하기 원하는 data는 다음과 같을 경우... 적용가능한 몇 가지 방법을 살펴보려 합니다.
bbb,ddd
fff,hhh
(아래 test는 10.2 에서 진행되었습니다.)
EXPLANATION
================================
1. DATA with Fixed-Length
data 내의 항목이 모두 fixed-length라면, POSITION을 사용하여 간단히 처리할 수 있습니다.
# target table
create table test (col1 varchar2(10),col2 varchar2(10))
# data
aaa,bbb,ccc,ddd
eee,fff,ggg,hhh
# control file
load data
infile test.dat
into table test
(col1 position(5:7) char,
col2 (13:15) char)
다음과 같은 결과를 확인할 수 있습니다.
SQL> select * from test;
COL1 COL2
bbb ddd
fff hhh
2. DATA with Variable-Length
그러나 data 내의 항목에 variable-length 항목이 있다면, POSITION을 사용할 수 없습니다.
따라서 다음과 같은 회피책을 고려해볼 수 있습니다.
(1) 일단 LOAD 완료 후, 필요 없는 COLOMN을 DROP합니다.
(2) 일단 LOAD 완료 후, CREATE TABLE ~ AS SELECT 를 통해 원하는 TABLE을 재생성합니다.
그런데 이런 형태의 작업은 부가적인 작업시간을 필요로 합니다.
[대안] 다음과 같이 SKIP할 data에 대해 FILLER를 사용하되, COLUMN NAME은 '존재하지 않는' 것으로 사용합니다.
# target table
create table test (col1 varchar2(10),col2 varchar2(10))
# data
aaaaa,bbbbbb,cccc,dddd
eee,ffffffffff,gggggg,hhh
# control file
load data
infile test.dat
into table test
fields terminated by ","
(col99 filler char, <--- 존재하지 않는 이름
col1 char,
col88 filler char, <--- 존재하지 않는 이름
col2 char)
다음과 같은 결과를 확인할 수 있습니다.
SQL> select * from test;
COL1 COL2
bbbbbb dddd
ffffffffff hhh

Use PL/SQL procedure to guard against malformed CSV files before upload

Hi all,
In my CSV upload utility, I've implemented error checking procedures, but they are invoked only AFTER data has been uploaded to temp table. This doesn't catch the following sample scenarios:
1. The CSV is malformed, with some rows shifted due to fields and separators missing here and there.
2. User has chosen a wrong CSV to upload (most likely number of fields mismatch)
I'm wondering if it is a good idea to have procedure to read in the CSV, scan each line, count the number of fields (null fields but with delimiters showing the field exist is ok) for each record. If every single record matches the required number of fields for that table, then the CSV is ok, and the insert from external table to temp table is allow. This will ensure at least the CSV file has a valid matrix size for the target table, but rest of error checking is left until after temp table is populated.
One of my concerns is, I specify "missing field values are null" in the external table parameters, which is necessary since not all fields are required. Does this specification causes a row with missing trailing separators still considered valid? If so then the stored procedure must be programmed to omit such a case.
What do you think? Many thanks.

Hi, Cuauhtemoc Amox
Thank you for your advice. I have set web adi using PL SQL interface.
I have decided to go futher
i have a procedure like that
procedure delete_old_data ( p_id in number, p_description in varchar2)
as
begin
               begin
               if g_flag ='N' then
               delete from xx_test;
                g_flag='Y';
                else null;
                end if;
                end;
insert into xx_test (p_id,p_descriptiom);
end;
G_FLAG is a global variable with default value ='N' in my package. When web_adi upload
first row from excel sheet, then procedure delete all data from table and change g_flag to 'Y'.
All other rows uploads succesfully; it works fine.
But when user change data in excel sheet and try to upload second time. DELETE_OLD_DATA procedure doesnt work in proper way.
I have found what problem is. when user use same template and try to upload data several times there is same SESSION_ID in database.
i.e. g_flag ='Y' when user try to upload second time. But when user log off and create template again it is work properly.
My question is: How i can different upload attempts? May be there is some id for each upload proccess.
if i can use this ID in my procedure user will have opportunity to use same template.
Thank you

SQL Loader combine fields into one.

Hi i am using sql loader to convert a db from sql server to oracle.
my SQL Server DB has a field for the date and another for the time, i want to convert this into on filed called date. I cannot seem to figure out how to do this.
my ctl file looks like this.
load data
infile '[Cell_Phones].[dbo].[Account_Details].dat' "str '<EORD>'"
into table MD_CELLPHONE.Account_Details
fields terminated by '<EOFD>'
trailing nullcols
Account_Number ,
Phone_Number ,
Call_temp FILLER,
Call_Date "TO_DATE(:Call_temp ||' ' ||':Call_Date', 'mm/dd/yyyy HH:miam')"
BEGINDATA
3817913.0<EOFD>1234567890.0<EOFD>2007-03-31 00:00:00<EOFD>4:25 PM<EOFD>3817913.0<EOFD>1234567890.0<EOFD>2007-03-24 00:00:00<EOFD>8:19 PM<EOFD>3817913.0<EOFD>1234567890.0<EOFD>2007-03-31 00:00:00<EOFD>4:25 PM<EOFD>
But if i run this i get the following error
SQL*Loader-291: Invalid bind variable CALL_TEMP in SQL string for column CALL_DATE.
basically i cant find a way to do this to combine 2 columns into one and discard the one i am not using.
Any help would be appreciated.
Jeff

Hello,
You can load the data as in a stg table and the move from stg table to regular table concatenating both call_temp and call_date column together.
load data
infile 'Cell_Phones.dbo.Account_Details.dat' "str '<EORD>'"
into table MD_CELLPHONE.Account_Details_stg
fields terminated by '<EOFD>'
trailing nullcols
Account_Number ,
Phone_Number ,
Call_temp,
Call_Date
Convert to right date format
Insert into account_details (col1 , col2, col3, ...) select val1 , val2 , to_date ( val3 || ' ' || val4) ...
from account_details_stg;
Regards
