Question for SQL Loader / IMP /EXPORT

hi all,
i just describe my example first : -
TABLE A have five columns.
a_column,b_column,c_column,d_column,e_column.
and have 1000 records.
i want to remove c_column & e_column and add f_column.
on TABLE A. which method (SQL Loader or IMP/EXP) is good suggestion for export & import data before take above action.
boris

Export/Import is the most appropiate solution for the task that you want to carry out because SQL*Loader is designed to load data into the database from flat files.
Regarding how to drop the two columns , you can do it
directly if you are working in 9i setting both columns as
unused after drop unused columns in the table.

How to set default directory for SQL LOADER

hi all,
i wanted to know how can we setup a default directory for SQL LOADER if at all we can. i connot place my control and data files in local system and use them at command prompt. rather i wanted to know if we can set default directory that the loader can use. this requirement is basically to enable all the clients to upload the data placed on the server and use the loader utility.
thanks in advance,
Basavraj

Ella,
You don't say which version of SQL Developer you are using via Citrix, but just setting the SQLDEVELOPER_USER_DIR hasn't worked for a long time (see Re: SQLDEVELOPER_USER_DIR does not function anymore). Also, since version 1.5, the default for the user directory (now set via ide.user.dir as shown below) is under the user profile area (relative to %APPDATA%), which you should be able to write to, even on Citrix.
Assuming that neither of those help, you will need to get whoever installed SQL Developer on the Citrix C: drive to modify the sqldeveloper.conf to have a line like, where the path exists for everyone who will be using the shared SQL Developer (assumes everyone has a H: drive):
AddVMOption -Dide.user.dir=H:\sqldeveloperAn alternative (depending on how you start SQL Developer via Citrix), is to create your own shortcut to start SQL Developer with something like:
sqldeveloper -J-Dide.user.dir="%SQLDEVELOPER_USER_DIR%"theFurryOne

Format input for Sql*Loader

Edited by: royce on Sep 18, 2008 2:08 AMActually, looking at your data again, you don't have a consistent format, so this makes it really difficult for something like SQL*Loader to process. If there were just e.g. 3 rows per record then that would be simple, but you are expecting SQL*Loader to look ahead to determine if there is more data or if it's reached the end of the record.
You would be better to load the data (external tables would probably make it quicker and easier as the data will come in the order as it is specified in the file, which would help as you have no group identifier against the sets of records) as it is and then use SQL to process them.
You haven't specified the resulting table that the data is loaded into. Is that just one single VARCHAR column with all the data concatenated or is it several columns (one for each name)?

Concatenate positions in control file for sql*loader utility.

Is there a way to concatenate several character positions in a control file for sql*loader???
example... field1 position(1:3) || position(5:7) ????
I would rather not create any unnecessary temp tables for a straight load...

How about...
/code
field1 position(1:7) char "substr(:field1, 1, 3) || substr(:field1, 5)"

Why no exclusive lock for conventional path loading for SQL*Loader?

why no exclusive lock for conventional path loading for SQL*Loader?
it use insert statement so it should use exclusive lock right?
thanks

ok, so only update statement would put a lock but not for insert statement?
because I have seen a situation where a user update rows in a sesssion (without commit) prevent another user update the rows.
thanks

Export data for SQL Loader

I have a table with the following 3 columns
Help_number Number(8,0)
Title Varchar(100 Byte)
Description Varchar (100 Byte)I would like to export all the data and import it into another table in another database. Im using SQL Developer to export the data. I choose the "LOADER" option but when the data is exported, the format is wrong. Here is an example of the data is exported.
"1","Error","Error 5343 - Input not recognised" The problem i have is that the first column is being exported in double quotes even though its of a type of NUMBER. When i try to load this using sqlldr it gets rejected because its a string.
The other problem that i have is that SQL Developer is not exporting all the rows if a table is big. I tried to export a table with 23000 rows and it only exported the first 55 rows.
Any help will be appreciated.

The quotes issue I am able to replicate and have logged a bug #6732587.
I have also logged a bug for the number of rows, however, if you click ctrl-end and then export, you'll get all the rows. Also, if you do not want to query back all the rows, but want to export all, in the Export dialog, just click the "where" clause tab and then Apply. This will also bring back all the rows. This bug is not only for Loader, but for any export format.

Export data ready for sql loader

Hi,
I need to export some data from my database ready to be used by sql loader ... what are tools can I use? Using sqlplus (i.e. spool file.csv select c1||";"||c2||";" from table; spool off) is the only tool I can use?

Hello,
You have multiple choices depending upon your oracle version on both source and target.
*1. Conventional export/import (no need to generate csv)*
*2. Datapump (10g)*
*3. Extracting .csv file using sql and loading using sqlldr*
*4. External table unloading data using datapump.*
*5. External table using .csv file generated via sql script.*

Is license required for Sql Loader?

I find that Sql Loader could save much time for me in bulk inserting.
But I'm not sure whether license is required for using it in business software developing.
Or is there any API that can provide similar functionality of Sql Loader?

The sqlldr utility, expdp and impdp, and sqlplus come with the rdbms license. Earlier client software had the option of installing sqlldr, exp, and imp onto the client machine for use against a remote database. Being that expdp and impdp only run on the database server now these two utilities are probably not included but sqlldr may still be available as part of the client.

Dumb question re Sql Loader in XP Client

Hi all,
I have a rather silly question. Previously I've worked exclusively in a Unix environment, but now find myself in XP.
I've done the full install of the Windows client for XP, but SQL*Loader is missing. I've RTFM'd, but can't find the necessary section. How do I get sql*loader installed in the XP environment?
Thanks (and apologies) in advance

IF you are talking of the 9i version, there should be the three database install disks (that contain both the database and the client tools). When you run the installer from the first disk from this set, you will have the option of installing the client tools (including SQL*Loader).

Changing the File path for SQL Loader Recognition

I am learning how to create a control file. The names.ctl file was placed in "Names" folder in my "C:\Windows" file.
I get the following error when trying to run the script for sqlldr:
Sql*Loader-500 Unable to open file.
Sql*Loader-553 file not found
Sql*Loader-System error: the system cannot find the specified file.
The path on the folder in c:\Windows\names\names.ctl
How do I make SQL Loader recognize it?

Pl post details of OS and database versions. Have you tried this ?
sqlldr CONTROL=c:\Windows\names\names.ctl ...HTH

The file consists of two lines and three columns.
Column1 has always 5 digits and is a String. Additional empty digits will be filled with blanks. Here: tommy and tom
Column2 has three digits and is a number. Here: 050 and 070.
Column 3 is also a number and consists of four digits. Additionally there is a fifth digit for the leading sign ("+" or "-"). Here: +3423 and -0006.

OWB 10gR2 : How to configure ctl and log locations for Sql*Loader mappings?

Hi all,
I'm using OWB 10gR2 to load data in tables with Sql*Loader mappings.
In my project I have a datafile module and an Oracle module.
When creating an sql*loader mapping in the oracle module, there is two properties for this mappings that I want to modify. The first is Control File Location and the second is Log File Location. Values for those properties are equal to the data file module location. When trying to change those values I can only chose "Use module configuration location".
Somebody knows how to configure those properties with different locations as the one of the flat file module?
What I want to do is to store the data file in one directory, and control file and log file in other directories.
Thank you for your help.
Bernard

Hi,
You're right, my problem is that the dropdown only show the location associated with the flat file location even if I have other file locations created in the design repository.
The good news is that I have found the solution to solve the problem :
1) Edit the file module and in tab "Data locations", add the locations you want to use for control file and log file.
2) Open configuration window of the mapping and then the dropdown for properties Control File Location and Log File Location show new locations
I have tested my mapping after changing those properties and it's working.

Could you guys please help me in writing the controller file to read the data from file and populate the table as described above. Thanks.

It is a little hard to tell exactly what your data file looks like and what you want your results to be, due to this forum mangling things a bit and adding extra lines and such. In general you can either use CONTINUEIF or CONCATENATE. I have demonstrated both below. When using CONTINUEIF, it assumes each additional line begins with the word "Permanent". When using CONCATENATE, it assumes each two lines constitutes one record. I have also used REPLACE to add a line feed in front of "Permanent", after it is removed during continuation or concatenation.
