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.

Does sql loader erase records?

When I use the sql loader for an existing table, does it clear the table of records and copy everything over...or does it simply add records? I don't want to go into the table and change everything w/o first finding out. Thanks for the help.
Cary =)

It depends on what you've specified in the control file. You can specify commands like insert, replace, truncate and append. I suggest you read the Oracle Utilities manual for your particular version for more information. There's also some good examples in the manuals. You can find Oracle manuals online at http://tahiti.oracle.com.
I don't want to go into the table and change everything w/o first finding out. I hope this statement doesn't mean you try things in a production environment without testing them first.

SQL LOADER Delete Records

Hello All,
I want to load records into a table using SQL Loader. I want to do the following(using a column in the data file),
1. If the flag is I insert the record.
2. If the flag is U update the record.
3. If the flag is D delete the record.
What are the options available in SQL Loader to achieve this.
Thanks,
Kannan.

Thanks,
Kannan.You have 2 solutions to acheive the result.
1.If you are running the sql loader on unix environment,then i suggest you to use AWK script to filter out the records,which you need (for Insertion/Updation) and discard the records which is of flag D in your data file.
For Example
If the name of your control file is load.txt,with file delimitter as "|" (pipe) the flag column is at 4th position then you can use awk script .
/home/bin/cat load.txt|nawk -F "|" '{ if ($4=="I" || $4=="U") print $0 }'|more2. Just load all the data onto table and filter out based upon the flag in table(Insertion/Updation/Deletion).
Hope this helps..

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

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 - 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,

SQL Loader newbie's question.

Hi all,
I have a delimiter file, e.g. data.dat, that contains the titles of each of the columns on the first row. Subsequent rows contain real column information/data. I didn't know how to create a control file, e.g. data.ctl, to create the table, its columns, and its data.
Currently, I got to create it manually, e.g.: table, columns, and used sql*loader to load in the data. Is there a better way to do this? Thank you very much for your help.

Yes, Sir. My external data is arranged as followed, e.g.:
"x","y","z"
"1","2","3"
"2","3","4"
"3","4","5"
where x, y, and z are the titles of the columns, not the data. My data are "1","2",...
Thank you very much for your response.

Sql loader control file question.

I have a text file (t.txt) which contains a record types AAA and AAB to input fixed width data into a table (t) AAA_NO, AAA_TYPE, AAB_DESC.
Control file (control_t) contents:
load data infile '/path/t.txt'
insert into table t
when ((1:3) = 'AAA' )
AAA_NO position (4:14) CHAR,
AAA_TYPE postion (15:27) CHAR
Works prefectly, but I need to add another set of data from the same t.txt file with record type AAB. I attempted to add this into the same control file:
into table t
when (1:3) = 'AAB'
AAB_DESC position (28:128) CHAR
It fails naturally. How would I include the addtional record type data into the same table after AAA_NO and AAA_TYPE have already been inserted? Do I need to include the AAA_NO in the second insert (AAB_DESC)? Should I create another temp table to store only the AAA_NO and AAB_DESC and then insert that data into table t after the loader is done? Or can this be completed in the same control file?

Thanks again for the assistance, this is a tough one to fix. I am new to sqlloader.
The temp table creation is causing some serious errors, so I am back to trying to fix sqlloader to get the job done. the apt.txt file contains records that each row of a new record starts with either 'APT' or 'ATT'. Here is the details of what I am trying to do.
crtl file:
load data
infile '/path/apt.txt
insert
into table t_hld
when ((1:3) = 'APT')
apt_no position (4:14) CHAR,
apt_type position (15:27) CHAR,
apt_id position (28:31) CHAR
The next section is the problem where I am inserting apt_sked into the same table t_hld as above because it has a different record qualifier its ATT and not APT.
insert
into table t_hld
when (1:3) = 'ATT'
apt_no position (4:14) CHAR,
apt_sked position (16:126) CHAR
The positions of the data using fixed is working, I can insert the apt_sked data into another temp table instead of t_hld and it works. It's just when I attempt to place the ATT apt_sked data into the t_hld table after the APT data has been loaded into the t_hld table....I tried APPEND instead of INSERT, but that does not work.
The APT_NO's of the data are all the same- it is the qualifier for the records (Primary Key attribute- however I do not have it established since it is a temp table concept).
I am stuck trying to get the data in the t_hld table, everything works when I do not try to put the ATT apt_sked data into t_hld- everything is valid. And placing the ATT apt_sked data into a different temp table works perfectly- but I can't find a way to create an update to t_hld from this temp table without errors. So I am trying to go back to sqlloader to get this done- any thoughts or questions?
Thanks a billion!

Hi,
Thank you for your advice.
I did insert a for loop and it loads all the items. In this case I know that I have 4 items in the file so it is okay to loop to 4. How can I loop to the last record not knowing how many are there. What do I need to put as the 4 to make it universal.
public void load(String filename)
         try {
                Map map = new HashMap();
                  Reference1 item;
               DataInputStream inStream = new DataInputStream(new FileInputStream(filename));
               for(int i = 0; i < 4; i++){
                     String code = inStream.readUTF();
                     double pr = inStream.readDouble();
                     int qty = inStream.readInt();
                     String auth = inStream.readUTF();
                     String pub = inStream.readUTF();
                     int yr = inStream.readInt();
                     String cat = inStream.readUTF();

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.

SQL Loader and record order

I am using sqlloader utility to load data from a CSV file in to a table.
My .ctl file looks as below
------- 8< -------
options (errors=5,SILENT=(HEADER, FEEDBACK),direct=true)
load data
infile "mytest.csv"
discardmax 0
into table owneruser.MY_TABLE
fields terminated by "," optionally enclosed by "##"
(ID, ID1, VAL, VAL2)
------- 8< -------
sqlldr tool is run with this ctl file by another database user who has sufficient privileges to insert this data in to mytest.csv has about 400000 entries each entry maps to one row in MY_TABLE. Before loading data using the sqlldr MY_TABLE is truncated.
In mytest.csv, the value for ID field is a number starting at 1 which keeps incrementing by 1 for the next entry. The records are ordered by ID in the csv file.
After loading the data using sqlldr, when we query MY_TABLE (select * from MY_TABLE), so far the records are returned in same order in which they were inserted (i.e. ordered by ID). But off late they are not being returned in random order. This happens only on one database instance. On other test instances the the resultset is ordered. I agree that the only way the order can be guaranteed is by using the ORDER BY clause.
But, I was wondering why this has worked even when ORDER BY is not used.
This is the only way in which MY_TABLE is manipulated. Rest all use it only for querying.
ID is the primary key column in MY_TABLE and there is an index on (ID, ID1).
Thanks in advance.
S

There are any number of reasons that the data would be coming back in a different order since you're not using an ORDER BY. My guess is that the most likely reason is that you have one or more extents in your table that is physically before another extent that it is logically after, in which case a full scan would read that extent first. You may also be seeing differences in how ASSM happens to choose which block to insert into, in the use of parallelism, etc.

Sql loader (catching record length error)

Guys is there any command in sqlldr that can catch record length error (less or more than certain length).I am using java to execute my sqlldr and would like to know if it is possible to catch those error.

Use CHAR instead aof VARCHAR
LOAD DATA
INFILE *
APPEND INTO TABLE test
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
first_id,
second_id,
third_id,
language_code,
display_text CHAR(2000)
)From the docu:
A VARCHAR field is a length-value datatype.
It consists of a binary length subfield followed by a character string of the specified length.

Fields terminated by (SQL loader, external table) question?

Hello.
I have a txt file which looks like:
Columns:
A..........B.........C...........D.........E..............F.............G...........H
739.......P.........0002......05........25012006..25012006..5...........data group
. = space
There are different number of spaces between columns.
What must i use in FIELDS TERMINATED BY to import this?
Thanks.

So, don't use FIELDS TERMINATED BY, but, as Ino suggested, fixed format, something like
LOAD DATA
TRUNCATE INTO TABLE <table name>
(a position(1:10),
b position(11:20),
c position(21:30),
d position(31:40),
e position(41:48) date "ddmmyyyy",
f position(51:58) date "ddmmyyyy",
g position(61:72),
h position(73:92))

How to use SQL loader with DBF fixed format record

Hi everybody!
My situation is that: I want to use SQL loader with Foxpro DBF format, it similar to case 2 study (Fixed format record) but DBF file has header, how can I tell SQL loader skip header.
Thank you in advance

Another option is to apply SQL operators to fields
LOAD DATA
   INFILE *
   APPEND
INTO TABLE emp
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"' (
   empno,
   ename,
   job,
   mgr,

   sal,
   comm,
   deptno CHAR TERMINATED BY ':',
   projno,
loadseq "my_seq.nextval")This is a modified control file of Case Study 3 which originally demonstrated the use of the Sequence parameter
