Server Utilities :: How To Handle Null Values In Sql Loader
Jul 16, 2009
I am using sql loader to load data to tables from tab delimeted files.
Here the problem is that the sql loader is not handling null values. If there is any null value in the flat file it is moving the field values to left and loading to the table. I am using NVL function to handle the null values, but it is not working.
My control file is:
LOAD DATA
INFILE 'C: da_poc_filesSQL_scriptsSourcefilesTRADEGLOBNODE1.TXT'
BADFILE 'C: da_poc_filesSQL_scriptsBadfilesTRADEGLOBNODE1.bad'
DISCARDFILE 'C:C: da_poc_filesSQL_scriptsDiscardfilesTRADEGLOBNODE1.dsc'
[Code]....
Source file is attached to this link For the attached file in the first record, tradedate value is coming in to tradeprice field
we have to load some serious amount of data into an oracle database. We have extracted data out of another database and the number format for negative values is e.g. 50.00- / Positive values doesn't have a plus in e.g. its 50.00.
Is there a way to format the 50.00- to like -50.00 during the load with SQL loader? I was thinking of a regular expression?
I want to insert into two separate tables using the following logic :
If date1 is not null or no1 is not null then insert into target_table1(id,date1,no1) If date2 is not null or no2 is not null then insert into target_table2(id,date2,no2)
I am experiencing somewhat same issue...but have been unable to resolve it(new to Oracle) I am getting the infile from flat file(data dump from SQL) using sqlldr to upload data to the Oracle table...since the data is already in the flat file...I cannot do anything in the SQL to pre-format the data...
Sample of ERROR I am getting - Column CREATE_DATE which has date and time - happens to other date time columns also if remove the CREATE_DATE from Control file(happens to every single line of record): ========================================== Record 2: Rejected - Error on table LGCY_CHS.METS_CHS_USER_PRIV, column CREATE_DATE. ORA-01841: (full) year must be between -4713 and +9999, and not be 0
the above error while tryin to run my control file in sqlloader as i need to load the csv data into oracle...what sequence i need to write so that i do not face the above error.
I need to load a file with fields separated by '|^|' and at end of each record has '||*||'.
So in my ctl file what do i mention ? fields terminated by '|^|' ? for the record termination wat should I say? Should I still mention 'trailing null col' in my ctl file...?
Sample data file: Name|^|Age|^|city||*|| john|^|33|^|||*|| james|^||^|nyc||*|| ken|^|44|^| washington||*||
the fields are properly terminated with |^| and the records are terminated with ||*||. Is it true that a file with |^| as field terminator cannot be loaded with sqlldr?
I installed oracle 10G complete so I can have everything. But now I cannot run sql loader. I check my oracle devsuitehome directory and I cannot find sqlldr.exe
I need to install sql loader separately? I can't find sql loader installer on web.
- 1 - M or P: indicates which table to insert: MASTER or PARENT; - 2 - M or A or B: indicates MASTER, PARENT_A, PARENT_B; - 3:18 - DATA.
Based on the values above, what I need to do is:
1. Load a line to MASTER_TABLE; 2. Load a line to PARENT_TABLE_A pointing to its relative line in MASTER_TABLE; 3. Load a line to PARENT_TABLE_B pointing to its relative line in MASTER_TABLE; 4. In the original file line, there is nothing I can use to join a MASTER line with a PARENT line.
The result would be: MASTER_ID PARENT_DATA 1 PARENT_TABLE_A1 1 PARENT_TABLE_B1 2 PARENT_TABLE_A2 2 PARENT_TABLE_B2
I tried to use both: SEQUENCE and Sequence.NextVall (CurrVal) but they only work when using ROWS=1 and the file I need to load has millions of rows, so I need direct path loading.Also, I read about External Table, but it does not suit my needs because the Application server is not the same as Database server, which is needed by external tables.
in this case is better load the data to a temporary table and then insert to the other tables, I found almost the same question in the topic pointed by the link below: URL....
I want to load geometry into a table using sql*loader. My datafile contains geometry defined as WKT URL...., a standard for geometry and also Oracle has a function called sdo_util.from_wktgeometry.If I'm using a separate 'insert into' statement using this function in sql*plus, there's no problem. But if I'm using the same function in my control-file for sql*loader import, I get a sql*loader-418 error: "bad datafile for column geometrie".
My data file contains records with RECORD_TYPE '01', '02', '03' and '04' in position (30:31) I use sql loader to load this data into a table. I need to load ONLY rows with RECORD_TYPE ='04'. I have to output all the other rows into a file, so I decided to use DISCARD file. Now, those with RECORD_TYPE ='4' have to be loaded into different columns depending on the value in position (267:268).
So, my ctl file should look something like:
WHEN (30:31) = '04' into table MYDATA WHEN (267:268) != 'O ' into table MYDATA WHEN (267:268) = 'O '
and whatever is not '04' goes to discard file.
I tried to use
into table MYDATA WHEN (30:31) = '04' and (267:268) != 'O ' into table MYDATA WHEN (30:31) = '04' and (267:268) = 'O '
but I don't get the right result in terms of the discard file.
Is there any way to put together all these conditions?
I am having issue with IMPDP on ORACLE VIRTUAL COLUMNS.I am having following table with Virtual column defined with Not null. Expdp is fine without any issue.
DDL : ------ CREATE TABLE alert_hist ( alertky INTEGER NOT NULL, alertcreatedttm TIMESTAMP(6) DEFAULT systimestamp NOT NULL, alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL NOT NULL
When I do the import (IMPDP) it got failed with the following error.
. . imported "TESTSCHEMA"."VALART" 359.1 KB 4536 rows ORA-31693: Table data object "TESTSCHEMA"."ALERT_HIST" failed to load/unload and is being skipped due to error: ORA-39097: Data Pump job encountered unexpected error -1
After that I dropped the Virtual Not null column and recreated that column with Nullable.
DDL : ----- alter table alert_hist drop column alertcreatedt; alter table alert_hist add alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL;
After that I took the expdp and impdp , it went fine with out any issue.
The SQL loader somehow is loading only first record. The data file is a csv and the end of line character is a new line. Some text fields have multiple new lines.
Here is my control file
load data infile '/home/devo/c0397105/RuleImport/testLoad/dummyLoad.csv' Truncate into table DUMMY_LOAD_TABLE fields terminated by "," optionally enclosed by '"' ( ID "to_number(:ID)",REQUESTED_GROUP,PURPOSE,COMMENTS) [code]........

I am using sqlloader for loading the data into database by using csv file.My csv file is delimited by comma in that i am having a column which is having the , and line feeds targeted to load into a long data type.for example as below
descri,dfdfdfd,dfdfdf, sdfsdf, dfsdfd,
i want to move this column data into a single table column.But due to because of delimited "," it is splitting into number of columns
I had a requirement of loading flatfile into staging table using SQL Loader, One of the columns in the the Flat file is having values FALSE or TRUE and my requirement is that I load 0 for FALSE and 1 for TRUE which can be achieved by simple DECODE function...I did use decode and tried to load several times but did not work.

I did try putting a trim as well as SUBSTR but did not work....the cloumn just doent get any values in the output (just null or say free space)
I have a small problem when I am trying to load data into a table using SQL Loader. The data I am trying to load should be a number, but it is in the format '999,999,999 USD'. When I try to load the data, I am getting an invalid number error, due to the USD (I have already accounted for the thousands seperators). My question is, how can I load the data as a number with USD in the format?
LOAD DATA APPEND INTO TABLE IPGITLREDATA WHEN ITL_REC_TYPE = 'D' FIELDS TERMINATED BY ',' TRAILING NULLCOLS (
[code].....
The data file might have a value of " D " instead of "D" for ITL_REC_TYPE and ITL_REC_TYPE is in the WHEN clause. How can I check for the trimmed value of ITL_REC_TYPE in the WHEN clause ?
I want to populate totale number of record in the file. Usually i get 10000 records per file and i load them using sql loader.I want to also insert the number of records in file while loading the data in table.
How can i achive it.
structure of control file is
load data BADFILE '/backup/temp/rajesh/RIO/BadFiles/FILENAME' append into table ERS_RIO_SRC TRAILING NULLCOLS ( INSTALLATION_ID CHAR
I have loaded 14324590 rows into target tables using sql*loader.I used below consideration during the load process.
1) direct=true,parllel=true 2) unrecoverable 3) disable all indexes and triggers.
But, sql loader takes 21 minutes to load 14324590 rows in database? tuning sql loader process? we cannot change data file because it has given by client.
from Control file, data is getting popupalated in TEST_USER and TEST_TITLE similarly if remove
INTO TABLE TEST_TITLE( TX_SID POSITION(1:3) CHAR, ID_TITLE "get_title_id(:TITLE_NAME)" ,

CREATE TABLE RD_ROLE_MASTER ( "ID_ROLE" NUMBER(38,0) NOT NULL ENABLE, "TX_ROLE_NAME" VARCHAR2(20 BYTE) NOT NULL ENABLE
[code]...
Here is RD_TITLE_MASTER script CREATE TABLE RD_TITLE_MASTER( "ID_TITLE" NUMBER(38,0) NOT NULL ENABLE, "TX_TITLE_NAME" VARCHAR2(25 BYTE) NOT NULL ENABLE);
Insert into RD_TITLE_MASTER (ID_TITLE,TX_TITLE_NAME) values (7,'RED_LOB_ESCALATION_L1'); what is the problem?

My requirement is to load the data from feed file into two tables based on the value of a column in feed file.
say column in feed file is "Activity_Value" . If the Activity_value is 10, the data from feed file should be loaded into Table A and If the Activity Value is 20 the data from feed file should be loaded into Table B.
