Sql Loader - Decimal numbers showing in null column

Greetings,
My apologies if this is in the wrong forum section. It seemed to be the most logical.
I have added new column to a control file used in a sql loader upload and I am getting unexpected results. Long story short, I copy foxpro tables from a network directory to my local pc. A foxpro exe converts these tables to .dat files. Sql loader then uploads the .dat files to matching oracle tables. I've run this program from my pc for years with no problems.
Problem now: We added a new column to a foxpro table and to the matching oracle table. This column in FoxPro in null for now - no data at all. I then added the new column to my ctl file for this table. The program runs, sql loader does it's thing with no errors. However, in the new field in Oracle, I'm finding decimal numbers in many of the records, when all records should have null values in this field. I've checked all other columns in the oracle table and the data looks accurate. I'm not sure why I'm getting these decimal values in the new column.
My log and bad files show no hints of any problems. The bad file is empty for this table.
At first I thought the positioning of the new column in the fox table, .ctl file and the oracle table were not lining up correctly, but I checked and they are.
I've double checked the FoxPro table and all records for this new column are null.
I'm not sure what to check for next or what to test. I am hoping someone in this forum might lend a clue or has maybe seen this problem before. Below is my control file. The new column is the last one: fromweb_id. It is a number field in both FoxPro and Oracle.
Thanks for any advise.

JOB_START date "mm/dd/yyyy",
JOB_END date "mm/dd/yyyy",
FROMWEB_ID)

I apologize for not explaining how this was resolved. Sql Loader was working as it should.
The problem was due to new fields being added to the FoxPro table, along with the fromweb_id column, that I was not informed about. I was asked to add a column named fromweb_id to the oracle jobs table and to the sql-loader program. I was not told that there were other columns added at the same time. In the foxpro table, the fromweb_id column was the last column added.
The jobs.dat file contained data from all columns in the foxpro table, including all the new columns. I only added the "fromweb_id" to the control file, which is what I was asked to do. When it ran, it was getting values from one of the new columns and the values were being uploaded into the fromweb_id column in Oracle. It is that simple.
When I had checked the FoxPro table earlier, I did not pickup on the other new columns. I was focussing in on looking for values in the fromweb_id column. When back-tracing data in the jobs.dat file, I found a value in the fromweb_id column that matched a value in a differnt column (new column) in FoxPro. That is when I realized the other new columns. I instantly knew what the problem was.
Thanks for all the feedback. I'm sorry if this was an inconvenience to anyone. I'll try to dig a little deeper next time. Lessons learned...
regards,

Hi,
I am trying to load a xml document into a xmltype column in a table using SQL*Loader and I receive this error:

If you were to use external tables instead of SQL*Loader, you can dynamically change the location of the external table (i.e. the filename) using a simple ALTER TABLE statement.
External tables also mean that all the control is inside the database rather than relying on external utilities and external scripts.

Sql loader & decimal point

Hello,
I need to import data with field containing floating point number. When I do this load on linux it goes ok. But when I try to load the same data from my windows there is problem with decimal point character. (My oracle server is 9i on linux).
I trid to use after logon trigger to issue statement alter session set nls_numeric_characters (enclosed in execute immediate statement) but it don't helped me.
Thanks for advice
sasa

ok.
I have following values in file to import:
45.5
50.3
60.2
38.7
("." is decimal point)
If I use sqlldr on linux it is imported correctly. If I try to to import data from windows machine I get error message ORA-01722: Invalid number. So somewhere on my windows machine is set another decimal separator and i would like to change it to ".". But i don't know where I can change it.
Is it more understandable?

I don't think so.
SQL> create table t (

rowid number)
ERROR at line 2:
ORA-00904: : invalid identifierPlease post your version number and the DDL for the table.
Best practice in Oracle is to NEVER, EVER, store a ROWID: They can change.
After you have solved the first problem, that you've never actually built the table, the solution to the sequence use is to make the call in your DML.
INSERT INTO t (testcol) VALUES (<sequence_name>.NEXTVAL);

Spaces value in sql loader

Is there a way to load in spaces using Sql*Loader given that the table it is loading to has a not null column but has a default value. My data file has spaces for a number field instead of zeros. Since my table column is declared as not null, it's failing even if I have a default value of '0' in my column.

You can tackle this in the control file. Here is a snippet from Oracle OnLine books - hopefully this will help out! Cheers.
==========================================
Setting a Column to Null or Zero
If you want all inserted values for a given column to be null, omit the column's specifications entirely. To set a column's values
conditionally to null based on a test of some condition in the logical record, use the NULLIF clause; see NULLIF Keyword. To set a
numeric column to zero instead of NULL, use the DEFAULTIF clause, described next.
DEFAULTIF Clause
Using DEFAULTIF on numeric data sets the column to zero when the specified field condition is true. Using DEFAULTIF on
character (CHAR or DATE) data sets the column to null (compare with Numeric External Datatypes). See also Specifying Field
Conditions for details on the conditional tests.
DEFAULTIF field_condition
A column may have both a NULLIF clause and a DEFAULTIF clause, although this often would be redundant.
Note: The same effects can be achieved with the SQL string and the DECODE function. See Applying SQL Operators to
Fields
NULLIF Keyword
Use the NULLIF keyword after the datatype and optional delimiter specification, followed by a condition. The condition has the same
format as that specified for a WHEN clause. The column's value is set to null if the condition is true. Otherwise, the value remains
unchanged.
NULLIF field_condition
The NULLIF clause may refer to the column that contains it, as in the following example:
COLUMN1 POSITION(11:17) CHAR NULLIF (COLUMN1 = "unknown")
This specification may be useful if you want certain data values to be replaced by nulls. The value for a column is first determined from
the datafile. It is then set to null just before the insert takes place. Case 6: Loading Using the Direct Path Load Method provides
examples of the NULLIF clause.
Note: The same effect can be achieved with the SQL string and the NVL function. See Applying SQL Operators to Fields.
Null Columns at the End of a Record
When the control file specifies more fields for a record than are present in the record, SQL*Loader must determine whether the
remaining (specified) columns should be considered null or whether an error should be generated. The TRAILING NULLCOLS
clause, described in TRAILING NULLCOLS, explains how SQL*Loader proceeds in this case.

Hi,
I am bit late ,I cannot say bit, If we use TRAILING NULL COLS in the control file your problem should be fixed.
TRAILING NULLCOLS tells SQL*Loader to treat any relatively positioned columns that are not present in the record as null columns.
For example, if the following data
10 Accounting
is read with the following control file
INTO TABLE dept
TRAILING NULLCOLS
( deptno CHAR TERMINATED BY " ",
dname CHAR TERMINATED BY WHITESPACE,
loc CHAR TERMINATED BY WHITESPACE
and the record ends after DNAME. The remaining LOC field is set to null. Without the TRAILING NULLCOLS clause, an error would be generated due to missing data.

How to make sqlldr handle mutliple NULL columns

I am using TRAILING NULL COLS in the control file to tell SQL*Loader to treat any relatively positioned columns that are not present in the record as null columns.
But the problem is occuring when there are multiple NULL columns one after the other. In that case SQL*Loader is treating continuous null column as 1 NULL column and then I am getting following message:
ORA-12899: value too large for column
And reason being wrong value is being tried to inserted in wrong column.
How can I stop SQL*Loader from combining multiple and continuous NULL columns and basically to make it treat each of them separately.

I have been able to take care of the issue using the NULLIF attribute. Here is how my control file looks now:
LOAD DATA
INFILE 'tab_sal_ldr.tab'
INSERT INTO TABLE SQL_TAB_LDR
REPLACE
FIELDS TERMINATED BY "\t"
TRAILING NULLCOLS
(COL1 CHAR,
COL2 INTEGER EXTERNAL NULLIF COL2=BLANKS,
COL3 FLOAT EXTERNAL NULLIF COL3=BLANKS,
COL4 DATE EXTERNAL NULLIF COL4=BLANKS)
However it is rejecting the rows having all NULLs. Is it possible to upload rows having all column values as NULL.
Following is the snippet from the log:
2 Rows not loaded because all fields were null.

SQL*Loader and ORA-00054

I was wondering if anyone knows a way to prevent ORA-00054 errors on tables when using SQL*Loader. I'm currently invoking scripts that extract data from a source system and load into a table in my database. I'm concurrently invoking the script because I have multiple source systems to improve my overall time for the loads. Sometimes, I get failures on the loads due to ORA-00054 errors. Can this be prevented? Is these a WAIT command/option that can be turned on for SQL*Loader?

desc toto
Name Null? Type
COL1 DATE
Controlfile :
load data
infile 'titi.dat'
truncate
into table titi
(col1 position(1:7) DATE "YYYYMMDD" "DECODE (:col1, '9999999','19990101','000000
0',null,:col1 + 19000000)")
Indeed, the input format date is SYYMMDD where S=0 if year=19xx and S=1 if Year=20xx.
Thanks for your reply.

Hi,
Now again I am facing problem..
I mean my log file throws error
"Record 2: Rejected - Error on table OWBREP.ADDRESS, column USER_GROUP.
ORA-12899: value too large for column "OWBREP"."ADDRESS"."USER_GROUP" (actual: 27, maximum: 2)"
and my record when I see in bad file is:
"0000810722,3,00000000,00000000,H,A,Y, , , , , ,1777 Hull Road, , , ,Mason,MI,48854, , , , ,12-MAR-02,N,0,,, ,00000000,0,FAC, , ,N,N, ,1777 Hull Road,Mason, MI 48854, , , , , , , ,12-MAR-02,10-FEB-05,FIX075_ADDR_VERSION_UPGRADE,00,,"
I have checked my control file and the table structure .They are same.
The problem is that I have an address field before this user_group column which has value like "Mason,MI,48854" .So sql loader is reading these as separate columns because of comma.That is why the order is getting messed up and I am getting this error.Can you suggest what should I do resolve this kind of error?

Oracle RAC and sql loader

hi all,
We have Oracle 10g RAC on IBM AIX
Today i will be uploading data in a table through sql loader.
I want that at the time of insertion only data which i am inserting goes into the table,As i am using sequence on particular column A.
Problem is If i shutdown database then i will not to able to insert data and if i doesnt shutdown db value for that column A is generated automatically when application works.
i have recommanded that we should stop connectivity of application with database then i will perform insertion but some people are saying no.Find other method
What steps should i do?

Ok i thing my question was not clear
I have table XYZ
A B C
1 2 3
4 4 5
if application is connected to database value to Coulmn is incremented
A B C
1 2 3
4 4 5
5 6 7
i have to insert into table XYZ using sql loader giving sequence (4,1) on column A.
But if it is connected to application it will give me error of PK.
as Value 5 is already inserted by application so how can i stop this.
so that i can have the max value of coulmn and start sequence
Hope this time make u clear.
sorry for bad english

Defaulting values SQL Loader

Hi All ,
I have a use case in sql loader where in i have two columns A and B in a Table.
   My Use case for control file is to get B from csv ( which is a mandatory column) . A is optional in CSV . if A is populated take that value for A . If not default if from B.
Thing i have tried is :
B                        ,
A EXPRESSION : "NVL( :A, :B) " ,
This is failing saying that
Invalid bind variable A in SQL string for column A.
Any ideas ? I know we could define a function. . But any better way to do with control files itself ?
Thanks,
Bibin
