SQL & PL/SQL :: Clob To Flat File?
Nov 20, 2012
Just wanted to export a clob field to .txt file, the maximum length of the clob field exceeds the limit 32767. So only partial data is exported to flat file. is there any way to export the entire data available in clob field irrespective of the size or lenght.
Length of the clob is 301829
l_file := UTL_FILE.fopen('LOCALDIR', '3.txt', 'w', 32767);
LOOP
DBMS_LOB.read (v_text_exp, l_amount, l_pos, l_buffer);
UTL_FILE.put(l_file, l_buffer);
l_pos := l_pos + l_amount;
END LOOP;

I am migrating data from DB2 to Oracle. I used DB2 export to extract the data specifying lobsinfile clause. This created all the CLOB data in one file. So a typical record has a column with a reference to the CLOB data. "OUTFILE.001.lob.0.2880/". where OUTFILE.001.lob is the name specified in the export command and 0 is the starting position in the file and 2880 is the length of the first CLOB.
When I try to load this data using sqlldr I'm getting a file not found.Attached is a copy of the control file and output from testing
PS. I cant use the DB2 option LOBSINSEPFILES which creates a separate file for each CLOB column because the table has over 14 million rows....and creating 14 mil files causes OS inode problems...
Attached File(s)
sqlldr.txt ( 2.05K )
Number of downloads: 3

working on loading the data from flat file into table and below given is the validation condition given.I checked the UTL_FILE build in package but not able to figure out, how to identify the column header in flat file.
1. Skip the header, if any. The header is the first record, and starts with '000'
2. Skip the trailer, if any. The Trailer is the last record, and starts with '999'
3. Log an error, but continue if a line exceeds 512 characters
4. Log an error, but continue if a line is blank

I am trying to build a data warehouse for Consumer Price Index and so I have downloaded data from the Bureau of Statistics.It is in excel format and since I am working with Oracle Warehouse Builder I have converted it to .csv file so that I can use it as a data source.
Question1: Is it practical to use single .csv file as a source of data for a data warehouse?
Question2: I have 3 dimensions tables and a fact table.The dimensions are one for the Region(as the date is organized in region,states etc),two is the consumer goods and services (as the data is organized in groups of goods and services, services/goods types) and finally time(year and month),
Now how am I going to do the mapping here?Is it possible to do a one to one mapping here as all data required by the dimensions is located in the .csv file.

In one of my projects I am exporting a couple of views into a flat file. The export utility is generic and uses dynamic sql to generate a flat file. We have a test environment and a production environment. On both the code is the same. We noticed that the output is different between the environments although it is supposed to be the same. If I export a view in the production I will get a record like this:
0020110107O0000000001|OTHER|07.01.11 08:06:00,296000|07.01.11 08:04:41,008000||0|0|EUR||NOT_FROZEN|MVOIP||IS_NORMAL_VERSION|MODIFIED|6863475590797607166|8648564326455689103|8011808169304472215|||CCP||||10000580||||DEKA|PS
In the test environment it will be like this:
0020110107O0000000001|OTHER|07-JAN-11 08.06.00.296000 AM|07-JAN-11 08.04.41.008000 AM||0|0|EUR||NOT_FROZEN|MVOIP||IS_NORMAL_VERSION|MODIFIED|6863475590797607166|8648564326455689103|8011808169304472215|||CCP||||10000580||||DEKA|PS
The code I am running is not changing any settings explicitly. It looks like this and it will be run as EXECUTE IMMEDIATE:
DECLARE
v_sql VARCHAR2 (32000);
v_sql_count NUMBER := 0;
v_error VARCHAR2 (4000);
v_new_file UTL_FILE.file_type;
BEGIN
[code]........
I also tried to do the following on production in order to get it equal to the test environment:
BEGIN
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_LANGUAGE = AMERICAN '
|| 'NLS_NUMERIC_CHARACTERS = ''.,'''
|| 'NLS_TIMESTAMP_FORMAT = ''DD-MON-RR HH.MI.SSXFF AM''';
END;
This would change the formatting for the timestamp columns for almost all files. Almost. Two of those files remain unchanged and still show the decimal separator from the old setting:
0020110107O0000000001|OTHER|07-JAN-11 08.06.00,296000 AM|07-JAN-11 08.04.41,008000 AM||0|0|EUR||NOT_FROZEN|MVOIP||IS_NORMAL_VERSION|MODIFIED|6863475590797607166|8648564326455689103|8011808169304472215|||CCP||||10000580||||DEKA|PSAny

I need to create an Oracle Stored Procedure to read a Flat file(pipe delimited) and load the data into an Oracle table. I believe the file should be located in any of the path as logged in dba_directories table or it can be anywhere on the local client machine?

I have a text file called ReturnedFile.txt. This is a comma separated text file that contains records for two fields.... Envelope and Date Returned.
At the same time, I have a table in Oracle called Manifest. This table contains the following fields:
Envelope
DateSentOut
DateReturned
I need to write something that imports the ReturnedFile.txt into a temporary Oracle table named UploadTemp, and then compares the data in the Envelope field from UploadTemp with the Envelope field in Manifest. If it's a match, then the DateReturned field in Manifest needs updated with the DateReturned field in UploadTemp.
I've done this with SQL Server no problem, but I've been trying for two days to make this work with Oracle and I can't figure it out. I've been trying to use SQL*Loader, but I can't even get it to run properly on my machine.
I did create a Control file, saved as RetFile.ctl. Below is the contents of the CTL file:
LOAD DATA
INFILE 'C:OracleTestReturnedFile.txt'
APPEND
INTO TABLE UploadTemp
FIELDS TERMINATED BY "'"
(
ENVELOPE,
DATERETURNED
)
If I could get SQL*Loader running, below is the code I came up with to import the text file and then to do the compare to the Manifest table and update as appropriate:
sqlldr UserJoe/Password123 CONTROL=C:OracleTestRetFile.ctl LOG=RetFile.log BAD=RetFile.bad
update Manifest m set m.DateReturned =
(select t.DateReturned
from UploadTemp t
where m.Envelope = t.Envelope
*)
That's all I got. As I said, I can't find a way to test it and I have no idea if it's even close.

I have read the following article:[URL] 11070I want to know wherer if there exists a possibility of write a clob or an xml into a file on disk, if we do not have the CREATE ANY DIRECTORY privilege. Many functions, like UTL_FILE.FOPEN, or dbms_xslprocessor.clob2file, or dbms_xmldom.writetofile, need an Oracle directory to be created (with CREATE OR REPLACE DIRECTORY...). But if we don't have this privilege, is there a possibility to export a clob into a file as xml (the clob contains 100% xml, but this is the column data type, CLOB) if we don't have that privilege?The clob data contains 48200 characters.

Iam using Oracle client 11g(32 bit) and Oracle database 11g on Unix server.
I have the created the following procedure to load XML file located in TEST_XML oracle directory( which is mapped to
DB/bulk01/REFLIB/REFDV/LOAD_XML) on the server.
Create or replace procedure TEST_LOAD_XML IS
dest_clob clob;

dst_offset NUMBER := 1;
src_offset NUMBER := 1;
lang_ctx number := DBMS_LOB.DEFAULT_LANG_CTX;
warning NUMBER;

when I execute the above procedure I get ORA-22288 file or LOB operation FILEOPEN failed No such file or directory error.
Looks like it did not find my oracle directory 'TEST_XML'
do I have to do anything like mapping? if so since my database is on unix server how do I map?

I am working with oracle 10g / 11. I need to operate with CLOB values of some table, unknown for me: I read them from .Net (3.5), and have to save them to files (Windows) to be loaded after this with DBMS_LOB. Lets say that table contains 3 columns (1 - CLOB) and several rows.
I want to store each CLOB value to separate file, and to store it after this into another DB table (another Instance, also). I cannot use dblinks and other techniques like this. The point is - how to avoid dealing with encoding?
I mean, that in the best scenario, I just want to save the CLOB values to the files, with no meter about Database Instance character set, language, and so on. How this can be accomplished? If I use default for .Net StreamReader UTF-8 format, the loading with DBMS_LOB failed.
If this is not possible, what will be the best way to determine the encoding, and to convert Oracle used encoding to .Net one?

1) Outfile file size is huge high compare then table segment data.
2) last column having extra space.
The output column is clob datatype. so i have added set long 50000 and set longchunksize 50000 parameter. after adding these only i got above issues. without two options, i am not getting this isssue but lines are wrapped.

I am trying to spool data from tables into flat files. I am using the following scripts to accomplish it
1. A cmd file (windows) that makes a call to a sql file
2. The SQL file which generates another query file at the run time, depending upon the table name passed to it
3. The run time query file , that executes the final query and spools the data into a txt file | delimited
For e.g. :
Actual command passed C:Spool_utilityspool_utility TABLE_NAME
E.g. of the spool utility file :
@echo off
SET dbuser=XX@YY
SET dbpw=xxxx
echo %date% - %time% - Start > %1%log.txt
echo START
sqlplus -s %dbuser%/%dbpw% @spool_utility.sql %1>%1.txt
echo %date% - %time% - Done >> %1%log.txt
echo DONE
E.g. of the spool_utility.sql
set echo off
SET newpage 0
SET feedback off
SET linesize 32767
set pagesize 0
[code]........
The above file generates a table_name.sql file with the actual table name at run time and gets executed and the output is written to the table_name.txt file.
This works perfectly fine. But the issue is when someone passes some wrong table name or if there is a actual run time error while executing the query , the error with details itself itself gets written to the end spool file.
For e.g. : if i do this just to generate an error and execute it from command line, the query generates an error and writes the error to the spool file , but at the command prompt where I executed the command I do not see any error and the process seems to have run perfectly well
set xxx on xxx off as above
spool &1.sql;
Prompt Select * from &1 where rownum><10---this will cause the issue
spool off
set termout ON
@ &1
EXIT
Eg of spool file generated :
from table_name WHERE rownum><=10 *
ERROR at line 62:
ORA-00936: missing expression
My question is, is there any way i can capture this runtime error and return this error to my calling sql script spool_utility.sql and then propagate it to the calling command file and do some tasks for eg removing the spool file and writing the actual error to a log file . Basically any way to know at my OS calling level that the entire spooling operation was unsuccessful.

I'm writing a PHP page to display some data from an Oracle database. Unfortunately, I can't copy the code because it's proprietary. One of the columns in the db is of type CLOB. I'm having trouble getting the data from the CLOB column.
The way the code is now, is there is a query string read into a variable, and the query string variable is read into a function that then retrieves the data from the db. Once the result set is returned, it is parsed to get data from all of the columns. The issue is that I've never worked with CLOB data before, so I'm having some difficulty extracting the data for that column. I know I can use the DBMS_LOB.READ function, but I'm not sure how to apply it in this case. The following is a generic form of the query string I'm using with b.clob_col being the column I'm having issues with.
$queryString = <<<EOD
SELECT a.col1,
a.col2,
a.col3,
b.col4,
b.col5,
b.clob_col,
from table1 b
inner join b.col4
on blah1
inner join a.col2
on blah2
where blah
and blah
EOD;
