UTL_FILE vs Oracle Tables

Hi Oracle Gurus,
I have a question, My team is using UTL_FILE to write process logs to physical files. My thinking is that if they use Direct tables to Insert process log its going to be faster compared to UTL_FILE. Am I right to think so?
Thanks,
Faisal.

But the output is different. How can you compare the two solutions? Of cause inserting into a table is faster then writing to the file. As with each rule there are exceptions, like locking conflicts, out of tablespace, etc.
But afterwards you do have no file. If you need a file, then use utl_file. If not then not.
Also backup strategies tend to play a role when dealing with large anmount of data. You might want those logs independent from the database or maybe you don't.

Import Text File to Oracle Table

Hi Guys,
Just needed some advice on how to approach this project. I need to set up an automated schedule to import a text file into an oracle table. There will be a folder set up, where a file is put every day for me. The file will have a name such as Name_Extract_<Date>. It will always start with the words Name_extract_ and the date appended to it. I need to import this text file into oracle, then perhaps copy the file to another folder when import is finished.
What will be the best method to use to accomplish this?? SQl Loader, UTL_FILE package? Any help will be appreciated.

Not much details but depending on versions etc of your Oracle database I'd look into external tables. Perhaps even leverage DBFS (only available in 11.2).

Generating an excel sheet from an oracle table

Hi,
What is the easiest way to generate an .xls report from oracle i.e. when the user for example views some records in an oracle table using SQL_FORMS I want to then give them a button where they get a simple .xls report of the records in the table.
I have heard 'ole' method is one way, is that the best method and how is it done exactly...?
Thanks

Have you tried this?
CREATE OR REPLACE procedure print_reports is
cursor c_mgr is
select

t1.empno
from

where exists
(select

from
emp t2
where

cursor c_direct_reports (cv_mgr number) is
select

ename,
job,
hiredate,
sal
from
emp
where
mgr=cv_mgr;
wfile_handle utl_file.file_type;
v_wstring varchar2 (100);
v_header varchar2(100);
v_file varchar2(100);

Help Required:How Upload Excel file Into Oracle Table Using PLSQL Procedure

Please Help , Urgent Help Needed.
Requirement is to Upload Excel file Into Oracle Table Using PLSQL Procedure/Package.

5. Cannot Use Util_File Package Or Oracle Directory to Place That File on Server.
6. we are Using Oracle 8.7
So Need Some PL/SQL Package or Fuction/ Procedure to Upload Excel file on User's Pc to Oracle Table.
Please Guide me wd some Code. or with Some Pl/SQL Package, or With SOme Hint. Or any Link ....

TEXT_IO is a PL/SQL package available only in Forms (you'll want to post in the Forms forum for more information). It is not available in a stored procedure in the database (where the equivalent package is UTL_FILE).
If the Terminal Server machine and the database machine do not have access to the file system on the client machine, no application running on either machine will have access to the file. Barring exceptional setups (like the FTP server on the client machine), your applications are not going to have more access to the client machine than the operating system does.
If you map the client drives from the Terminal Server box, there is the potential for your Forms application to access those files. If you want the files to be accessible to a stored procedure in the database, you'll need to move the files somewhere the database can access them.

How to read RMAN data into an ORACLE Table?

Hallo,
With regards to RMAN, how should we store the data into a database table, from the commands which can run only on RMAN prompt without using Recovery Catalog?
For Example:
RMAN> Report need backup days 3;
RMAN DATA:
RMAN-03022: compiling command: report
Report of files whose recovery needs more than 3 days of archived logs
File Days Name
1 1203 D:\ORACLE\ORADATA\TEST\SYSTEM01.DBF
2 1203 D:\ORACLE\ORADATA\TEST\RBS01.DBF
3 1203 D:\ORACLE\ORADATA\TEST\USERS01.DBF
Should it done via UTL_FILE?
If so, could someone give simple example/code how to do that, in order to write this RMAN data into an Oracle Database table?
I also set the utl_file_dir parameter to a particular directory in my database.
Thanks
W.Benvort

Actually, I am not using Recovery Catalog, so the views like RC_database, Rc_tablespaces etc , which are specific to recovery catalog are not available.
r.- this make sense at 100% because those views belong to the recovery catalog.
So, I wanted that these information, which we can get via using the commands like above, transfer into an Oracle table
r.- If you want to access the views of the Recovery Catalog to store part of that information in tables you have to have the database registered in a Recovery Catalog.
Should we keep the Recovery Catalog in Control file? Instead of using separate Schema.
r.- I recommend you to create a catalog for your database because the space the controlfile to store information regarding RMAN is reused and you can lose important information about your backups.
Can we run Catrman.sql script as a sys in order to keep the recovery catalog in sys schema?
r.- As you know, this is not recommended at all.
Conclusion : Create a Recovery Catalog and you will be able to perform all that you want regardind what you mentioned above.
I have a thread for this:

1.is it possible to read a .xls file and load it into an oracle table

1.is it possible to read a .xls file and load it into an oracle table, using oracle database or oracle forms i.e. either utl_file, or text_io, or any other oracle tool.
As far as I know we need a csv file or a txt ( tab delimited) file ?
2.Are there any windows tools for the same

Hi,
If you want to use the DDE package to read the XLS file then yes, you will neeed to know the number of rows and columns in the input file.
i.e. How will you know :
1) How many columns are there in the input file.
If I have a XLS file with the following data :
R1C1 R1C2 R1C3 R1C4 R1C5 R1C6 R1C7
xxx xx x
Where R represents row and C represents column, then how will you know the each row has 7 columns. If you know the answer upfront, then it's not a issue.
Using the DDE apprach, you will have to specify the RowNum and the ColumnNo of each idividual cells to read/write data from xls sheet.
Look at the syntax in my ealier post.
using the other approch (i.e. comma delimited text file - CSV file) , you need not know the number of columns as you can loop thru the input record till the last column is read.
All you have to do is to look for the 'n' occurances of the field delimiter say ',', do a substr from the current position to the point where the ',' was found.
This process is to be repeated in a loop till all columns are read.
The TEXT_IO package can trap for EOF (End Of File).
Hope I made myself clear.

Updating an oracle table with data from an xml string

Hi - I need help with the following problem:
We have a table in the database with a field of xml type. We are going to take each string that gets inserted into the xml type field in the 'xml table' and parse the data into another oracle table with corresponding fields for every element.
once the record gets inserted into the 'real table' the user might want to update this record they will then insert another record into the 'xml table' indicating an update(with a flag) and then we need to update the 'real table' with the updated values that have been sent in.
The problem that I am having is that I do not know how to create this update statement that will tell me which fields of the table need to be updated.(only the fields that need to be updated will be in the xml string in the 'xml table').
Please help me with this - ASAP!

Are you wanting to upload the file through an Oracle Form or just upload a file? If it isn't via forms, then you should probably post your question here: {forum:id=732}
You also should post the version of Forms, Database, etc...
As far as uploading files via a text file, I personally like to use Oracle External Tables even in Forms. You can Google that and there is plenty of information. If you search this forum, then you will see lots of people use UTL_FILE in forms, but you can Google that also for more information.

Convert oracle tables

Hi,
Is there any third party tool/source which will unload data from oracle tables into flat files? Iam talking few millions of records...
thanks

Hi,
there are some possibilities. One is discussed in
http://technet.oracle.com:89/ubb/Forum88/HTML/000862.html
It is a sqlplus Script to produce the file.
Another way is UTL_FILE from inside a PL/SQL Procedure
Or use SQL Navigator from Quest http://www.quest.com . It works on my tables, but I don't have several million rows inside.

Best Practice to fetch SQL Server data and Insert into Oracle Tables

Hello,
I want to read sqlserver data everry half an hour and write into oracle tables ( in two different databases). What is the best practice for doing this?
We do not have any database dblinks from oracle to sqlserver and vice versa.
Any help is highly appreciable?
Thanks

Well, that's easy:
use a TimerTask to do the following every half an hour:
- open a connection to sql server
- open two connections to the oracle databases
- for each row you read from the sql server, do the inserts into the oracle databases
- commit
- close all connections

Insert /delete data from SAP Z table to Oracle table and opposite

Hi,
Can u help me write this FM from the SAP side?
So, I have two tables ZTABLE in SAP and Oracle table ORAC.
Let's put three columns in each of them, for example
TEL1
TEL2
ADRESS
NAME
where TEL field is primary from ZTABLE to ORAC...
(in FM there shoud be abap code for writing data in ZTABLE after we press some pushbutton made in sap screen painter..)
for example, when we write new record in ZTABLE
00
112233
Street 4
Name1
this data shoud be inserted in Oracle table ORAC.
when we write new record in Oracle table for example
01
445566
New Street
Name2
this data shoud be inserted in ZTABLE.
Field TEL1 can be only of two values 01 or 02, other combination is not valid...
I must have all data from Oracle table ORAC in ZTABLE and opposite.
It should be the same scenario for DELETE...
And this communication should be online between sap and table in oracle database...
Can u help me from sap side? and give idea how to configure on oracle side??
Thanks a lot,
Nihad

I dont know if we can directly connect to a oracle database ( wait for the answers from others on this )
but in XI we have the JDBC adaptor to insert and retrieve data.
so for the outbound from SAP the flow can be something like this (with XI in landscape):
1) You have a screen to maintain a new entry / delete an entry
2) On save , this record gets saved or deleted from the Ztable in SAP
3)) In the same screen you can call a proxy class-method (generated using SPROXY transaction ) to send the record to XI.
4) XI to format it and insert into the oracle table
