SQL loader and PL/SQL

A text file contains a single row with 450 comma separated entries.I want to load all the data into an oracle table of 450 columns(separating the comma separated entries e.g A1,2,3 from text file into oracle table as
col1 col2 col3
A1 2 3
but sql loader gives a problem while loading data into more than 250 fields.So how to tackle this problem.
Please reply soon at [email protected] or [email protected]

That or you will need to use UTL_FILE in read mode. You will probably want to write a function which parses the commas. There are tons floating around here or on ASKTOM. I am not exactly sure however the max linesize UTL_FILE can read, but it should be a viable option.

SQL Loader and Insert Into Performance Difference

Hello All,
Im in a situation to measure performance difference between SQL Loader and Insert into. Say there 10000 records in a flat file and I want to load it into a staging table.
I know that if I use PL/SQL UTL_FILE to do this job performance will degrade(dont ask me why im going for UTL_FILE instead of SQL Loader). But I dont know how much. Can anybody tell me the performance difference in % (like 20% will decrease) in case of 10000 records.
Thanks,
Kannan.

Do not confuse the topic, as I told im not going to use External tables. This post is to speak the performance difference between SQL Loader and Simple Insert Statement.I don't think people are confusing the topic.
External tables are a superior means of reading a file as it doesn't require any command line calls or external control files to be set up. All that is needed is a single external table definition created in a similar way to creating any other table (just with the additional external table information obviously). It also eliminates the need to have a 'staging' table on the database to load the data into as the data can just be queried as needed directly from the file, and if the file changes, so does the data seen through the external table automatically without the need to re-run any SQL*Loader process again.
Who told you not to use External Tables? Do they know what they are talking about? Can they give a valid reason why external tables are not to be used?
IMO, if you're considering SQL*Loader, you should be considering External tables as a better alternative.

SQL *Loader and External Table

Hi,
Can anyone tell me the difference between SQL* Loader and External table?
What are the conditions under we can use SQL * Loader and External Table.
Thanx

External tables are accessible from SQL, which generally simplifies life if the data files are physically located on the database server since you don't have to coordinate a call to an external SQL*Loader script with other PL/SQL processing. Under the covers, external tables are normally just invoking SQL*Loader.
SQL*Loader is more appropriate if the data files are on a different server or if it is easier to call an executable rather than calling PL/SQL (i.e. if you have a batch file that runs on a server other than the database server that wants to FTP a data file from a FTP server and then load the data into Oracle).

Help in calling sql loader and an oracle procedure in a script

Hi Guru's
please help me in writing an unix script which will call sql loader and also an oracle procedure..
i wrote an script which is as follows.
!/bin/sh
clear
#export ORACLE_SID='HOBS2'
sqlldr USERID=load/ps94mfo16 CONTROL=test_nica.ctl LOG=test_nica.log
retcode=`echo $?`
case "$retcode" in
0) echo "SQL*Loader execution successful" ;;
1) echo "SQL*Loader execution exited with EX_FAIL, see logfile" ;;
2) echo "SQL*Loader execution exited with EX_WARN, see logfile" ;;
3) echo "SQL*Loader execution encountered a fatal error" ;;
*) echo "unknown return code";;
esac
sqlplus USERID=load/ps94mfo16 << EOF
EXEC DO_TEST_SHELL_SCRIPT
it is loading the data in to an oracle table
but the procedure is not executed..
any valuable suggestion is highly appriciated..

HELP: SQL*LOADER AND Ref Column

Hallo,
I have already posted and I really need help and don't come further with this
I have the following problem. I have 2 tables which I created the following way:
CREATE TYPE gemark_schluessel_t AS OBJECT(
gemark_id NUMBER(8),
gemark_schl NUMBER(4),
gemark_name VARCHAR2(45)
CREATE TABLE gemark_schluessel_tab OF gemark_schluessel_t(
constraint pk_gemark PRIMARY KEY(gemark_id)
CREATE TYPE flurstueck_t AS OBJECT(
flst_id NUMBER(8),
flst_nr_zaehler NUMBER(4),
flst_nr_nenner NUMBER(4),
zusatz VARCHAR2(2),
flur_nr NUMBER(2),
gemark_schluessel REF gemark_schluessel_t,
flaeche SDO_GEOMETRY
CREATE TABLE flurstuecke_tab OF flurstueck_t(
constraint pk_flst PRIMARY KEY(flst_id),
constraint uq_flst UNIQUE(flst_nr_zaehler,flst_nr_nenner,zusatz,flur_nr),
flst_nr_zaehler NOT NULL,
flur_nr NOT NULL,
gemark_schluessel REFERENCES gemark_schluessel_tab
Now I have data in the gemark_schluessel_tab which looks like this (a sample):
1 101 Borna
2 102 Draisdorf
Now I wanna load data in my flurstuecke_tab with SQL*Loader and there I have problems with my ref column gemark_schluessel.
One data record looks like this in my file (it is without geometry)
1|97|7||1|1|
If I wanna load my data record, it does not work. The reference (the system generated OID) should be taken from gemark_schluessel_tab.
LOAD DATA
INFILE *
TRUNCATE
CONTINUEIF NEXT(1:1) = '#'
INTO TABLE FLURSTUECKE_TAB
FIELDS TERMINATED BY '|'
TRAILING NULLCOLS (
flst_id,
flst_nr_zaehler,
flst_nr_nenner,
zusatz,
flur_nr,
gemark_schluessel REF(CONSTANT 'GEMARK_SCHLUESSEL_TAB',GEMARK_ID),
gemark_id FILLER
BEGINDATA
1|97|7||1|1|
Is there a error I made?
Thanks in advance

Using SQL*Loader and UTL_FILE to load and unload large files(i.e PDF,DOCs)

Problem : Load PDF or similiar files( stored at operating system) into an oracle table using SQl*Loader .
and than Unload the files back from oracle tables to prevoius format.
I 've used SQL*LOADER .... " sqlldr " command as :
" sqlldr scott/[email protected] control=c:\sqlldr\control.ctl log=c:\any.txt "
Control file is written as :
LOAD DATA
INFILE 'c:\sqlldr\r_sqlldr.txt'
REPLACE
INTO table r_sqlldr
Fields terminated by ','
id sequence (max,1) ,
fname char(20),
data LOBFILE(fname) terminated by EOF )
It loads files ( Pdf, Image and more...) that are mentioned in file r_sqlldr.txt into oracle table r_sqlldr
Text file ( used as source ) is written as :
c:\kalam.pdf,
c:\CTSlogo1.bmp
c:\any1.txt
after this load ....i used UTL_FILE to unload data and write procedure like ...
CREATE OR REPLACE PROCEDURE R_UTL AS
l_file UTL_FILE.FILE_TYPE;
l_buffer RAW(32767);
l_amount BINARY_INTEGER ;
l_pos INTEGER := 1;
l_blob BLOB;
l_blob_len INTEGER;
BEGIN
SELECT data
INTO l_blob
FROM r_sqlldr
where id= 1;
l_blob_len := DBMS_LOB.GETLENGTH(l_blob);
DBMS_OUTPUT.PUT_LINE('blob length : ' || l_blob_len);
IF (l_blob_len < 32767) THEN
l_amount :=l_blob_len;
ELSE
l_amount := 32767;
END IF;
DBMS_LOB.OPEN(l_blob, DBMS_LOB.LOB_READONLY);
l_file := UTL_FILE.FOPEN('DBDIR1','Kalam_out.pdf','w', 32767);
DBMS_OUTPUT.PUT_LINE('File opened');
WHILE l_pos < l_blob_len LOOP
DBMS_LOB.READ (l_blob, l_amount, l_pos, l_buffer);
DBMS_OUTPUT.PUT_LINE('Blob read');
l_pos := l_pos + l_amount;
UTL_FILE.PUT_RAW(l_file, l_buffer, TRUE);
DBMS_OUTPUT.PUT_LINE('writing to file');
UTL_FILE.FFLUSH(l_file);
UTL_FILE.NEW_LINE(l_file);
END LOOP;
UTL_FILE.FFLUSH(l_file);
UTL_FILE.FCLOSE(l_file);
DBMS_OUTPUT.PUT_LINE('File closed');
DBMS_LOB.CLOSE(l_blob);
EXCEPTION
WHEN OTHERS THEN
IF UTL_FILE.IS_OPEN(l_file) THEN
UTL_FILE.FCLOSE(l_file);
END IF;
DBMS_OUTPUT.PUT_LINE('Its working at last');
END R_UTL;
This loads data from r_sqlldr table (BOLBS) to files on operating system ,,,
-> Same procedure with minor changes is used to unload other similar files like Images and text files.
In above example : Loading : 3 files 1) Kalam.pdf 2) CTSlogo1.bmp 3) any1.txt are loaded into oracle table r_sqlldr 's 3 rows respectively.
file names into fname column and corresponding data into data ( BLOB) column.
Unload : And than these files are loaded back into their previous format to operating system using UTL_FILE feature of oracle.
so PROBLEM IS : Actual capacity (size ) of these files is getting unloaded back but with quality decreased. And PDF file doesnt even view its data. means size is almot equal to source file but data are lost when i open it.....
and for images .... imgaes are getting loaded an unloaded but with colors changed ....
Also features ( like FFLUSH ) of Oracle 've been used but it never worked
ANY SUGGESTIONS OR aLTERNATE SOLUTION TO LOAD AND UNLOAD PDFs through Oracle ARE REQUESTED.
------------------------------------------------------------------------------------------------------------------------

Thanks Justin ...for a quick response ...
well ... i am loading data into BLOB only and using SQL*Loader ...
I've never used dbms_lob.loadFromFile to do the loads ...
i 've opend a file on network and than used dbms_lob.read and
UTL_FILE.PUT_RAW to read and write data into target file.
actually ...my process is working fine with text files but not with PDF and IMAGES ...
and your doubt of ..."Is the data the proper length after reading it in?" ..m not getting wat r you asking ...but ... i think regarding data length ..there is no problem... except ... source PDF length is 90.4 kb ..and Target is 90.8 kb..
thats it...
So Request u to add some more help ......or should i provide some more details ??

Import and process larger data with SQL*Loader and Java resource

Hello,
I have a project to import data from a text file in a schedule. A lager data, with nearly 20,000 record/1 hours.
After that, we have to analysis the data, and export the results into a another database.
I research about SQL*Loader and Java resource to do these task. But I have no experiment about that.
I'm afraid of the huge data, Oracle could be slowdown or the session in Java Resource application could be timeout.
Please tell me some advice about the solution.
Thank you very much.

Change the mapping generation code from sql*loader to pl/sql

I want to use a mapping with a flat file operator to generate pl/sql code even if a mapping generate sql*loader code as default.
I tried to change the Language generation property of the mapping but an API8548 error message is shown. The suggested solution by OWB is to change the language generation code in the property inspector of the mapping.
I can't use external table because I have to work with a remote machine.
What i have to do to change the generation code from SQL*Loader to PL/SQL?

How about breaking this out into 2 mappings? In the first mapping, map a flat file operator to an table using SQL*Loader code. Then define a second mapping using the table as source and therefore generate PL/SQL. Then use process flow to launch the 2nd map to run after completion of first.

SQL, PL/SQL Expression and PL/SQL function

In a Post Calculation Computation field I wanted the following computation:
if B is X
then
field = A
else
field = B
end if;
or as a decode
Decode(B,X,A,B)
I could not get this to work so I wrote a database function that simulates the decode. So when I put:
My_decode(B,X,A,B)
in the field it did work.
Basically I am not sure what kind of code one is expected to put into SQL, PL/SQL Expression and PL/SQL function fields. Can someone give an example of each? Also the APEX help is sometimes incorrect.
For example if you click the "Post Calculation Computation" label it says:
The For example, if this item is named P1_X, you could use post calculation expressions such as UPPER(:P1_X), INITCAP(:P2_Y), MIN(:P1_X,:P2_Y-200), NVL(:P1_X,:P2_Y), or a function call such as return my_func(:P1_X); to set the final value of the item.
But if you put return my_func(:P1_X); in the field you get an error. It should be just my_func(:P1_X);
thanks Rene

DECODE is only available in SQL, so would have to be used in a SQL Expression.Yes, that's what APEX keeps telling me when I use in in a field that has "SQL or PL/SQL expression" above it. So what do you put in the field?

Running SQL Loader through PL/SQL

Hi All,
Is there a utility package that can be used to run SQL LOADER through PL/SQL?
Regards

External tables are new in 9i.
If you need to call SQL*Loader in 8i, you'd be stuck with the Java stored procedure/ external procedure approach. Of course, this might also be an impetus to upgrade, since 8.1.7 leaves error correction support at the end of the year.

Differ java.sql.* and javax.sql.*

Dear Friends,
What is differenece between java.sql.* and javax.sql.*?.
Advance in thanks

java.sql is the package you can use for all basic kinds of database access. If you are not developing a full scale enterprise application, java.sql package is all that you need.
javax.sql is extension to the basic java.sql package. It includes classes that allow connection pooling and rowsets, among others.
If you are just getting started with JDBC, you just need to get familiar with java.sql and leave the wonders of javax.sql until later.

I need some working examples with pl/sql records and pl/sql tables.

i am new to pl/sql tables and pl/sql records. i need some working examples on pl/sql records and pl/sql tables from basics to hoghlevel.how to use then procedures and functions and packages.

i am new to pl/sql tables and pl/sql records. i need some working examples on pl/sql records and pl/sql tables from basics to hoghlevelThere is no such thing as PL/SQL "+tables+". This is a misnomer and creates the perception that a PL/SQL "table" is somewhat like a SQL table. Nothing can be further from the truth. The correct term is "+collection+" or "+associative array+". Compared to SQL tables, these are very primitive structures, very rigid structures, cannot scale, and can be quite expensive memory wise.
That is not to say do not use an associative array or collection. These are very useful tools.. but only when applied correctly. Like using a collection for a bulk fetch to transfer more rows between the PL and SQL engines and thus decrease context switching.
Unfortunately, quite often we see the row-by-row and slow-by-slow approach - where the developer uses SQL as an I/O only layer, pulls rows into expensive PL engine memory into record structures and arrays, and then process the rows there.
So before looking at working example (even the wrong approach's code will compile and run and work in practice), make sure that you know the fundamentals of correctly using the PL engine and correctly using the SQL engine. And these fundamentals can be summed up into a very basic rule:
Maximize SQL. Minimize PL/SQL+
Get this rule right, and you will have a sound foundation for writing performant and scalable Oracle applications.

SQL*Loader and DECODE function

Hi All,
I am loading data from data files into oracle tables and while loading the data using SQL*Loader, the following requirement needs to be fulfilled.
1) If OQPR < 300, RB = $ 0-299, SC = "SC1"
2) If 300 < OQPR < 1200, RB = $ 300-1199, SC = "SC2"
3) If 1200 < OQPR < 3000, RB = $ 1200-2999, SC = "SC3"
4) If OQPR > 3000 USD, RB = > $3000, SC = "SC4"
Here OPQR is a field in the data file.
Can anyone suggest how do we handle this using DECODE function? Triggers and PL/SQL functions are not to be used.
TIA.
Regards,
Ravi.

The following expression gives you different values for your different intervals and boundaries :
SIGN(:OQPR - 300) + SIGN(:OQPR - 1200) + SIGN(:OQPR - 3000)
