Sql loader user identification

Hi, there:
Can anyone tell me if I can run sql loader with an extenally identified user so that I don't have to provide a database password for that user when I run sql loader in a batch file? Thanks.

Include the schema name along with the table name as part of the INTO TABLE clause. For example;
INTO TABLE SCOTT.EMP

SQL Connection Failed for SCCM 2012 R2 (Unable to load user-specified certificate)

We've recently completed an upgrade from SCCM 2012 SP1 to 2012 R2 and have been running in the new environment for about a week. As of this morning, The consoles failed to connect to the CAS' and one of the Primary Site's database. The issue was resolved
easily enough by addressing a certificate issue in SQL, but I'm left wondering if there's a correlation between the SP1-to-R2 upgrade that would cause the cert to fail. Anyone have experience with this?

We got the same certificate related error events after a fresh install of SCCM 2012 R2 on a new server. It happened during the first reboot after SCCM was installed. In the Certificates mmc, I right-clicked on the certificate used by SQL and chose Manage
Private Keys. Giving the service account that runs the MSSQLSERVER service read rights to the private key allowed SQL to start. However, after a day or so we rebooted the server again, and SQL wouldn't start. Something had removed the service account's read
permission. Since the SCCM configuration wasn't that far along, we uninstalled SCCM. After giving the service account read rights again, and rebooting several times over a few days, and SQL started every time. We then installed SCCM 2012 R2 again, and checked
the certificate's permissions before rebooting. The service account still had read permissions when the install completed, but as soon as the server was rebooted, it lost the permissions again.
The Certificates mmc was then used to request a second computer certificate and then SQL was configured to use that new certificate via SQL Server Configuration Manager. After several days and a number of reboots the SQL services have started normally every
time so the second certificate seems to have fixed the issue. I have kept the original certificate for fear that removing it will cause whatever part of SCCM 2012 R2 that modifies the original certificate to start removing permissions from the new certificate
as well.

Using User function in SQL*Loader

Hi, I have created the following control file. I am using DIRECT path insert. I am using a function to retrieve the column system_date. However, when I am running sql*loader, the fields system_date and load_date are loaded with null value.

No,
You can not call PL/SQL functions in DIRECT PATH mode, also this is documented, so you should not need to ask.

Loading two tables at same time with SQL Loader

I have two tables I would like to populate from a file C:\my_data_file.txt.
Many of the columns I am loading into both tables but there are a handful of columns I do not want. The first column I do not want for either table. My problem is how I can direct SQL Loader to go back to the first column and skip over it. I had tried using POSITION(1) and FILLER for the first column while loading the second table but I got THE following error message:
SQL*Loader-350: Syntax error at line 65
Expecting "," or ")" found keyword Filler
col_a Poistion(1) FILLER INTEGER EXTERNALMy control file looks like the following:
LOAD DATA

SQL Loader Inserts chr(13) and chr(10) in the first column of every row.

Hi,
I have exported a data in a pipe delimited file using TOAD in one database. Now I want to load the data in my local database using SQL Loader. However every time I try to load the data a double quote followed by a new line is entered for the first column of each row. Unfortunately the delimited file is very big and hence can't be posted here. However I tried the same with a customized table and its data and found the same problem. Below are the table structures and control file that I used.
create table test_sql
a varchar2(30),
b date
insert into test_sql values('51146263',sysdate-3);
insert into test_sql values('51146261,sysdate-1);
EXPORTED PIPE DELIMITED FILE_
A|B|!##!
51146261|04/14/13 4:55:18 PM|!##!
51146263|04/12/13 4:55:32 PM|!##!
create table test_sql1 as select * from test_sql where 1=2;
CONTROL FILE_
OPTIONS(SKIP=1)
LOAD DATA
INFILE 'C:\Users\Prithwish\Desktop\Test.txt' "str '!##!'"
PRESERVE BLANKS
INTO TABLE TEST_SQL1
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
A CHAR(2000),
B DATE "MM/DD/YYYY HH12:MI:SS AM"
select * from TEST_SQL1;
After this when I paste it in notepad I get the following result
A B
51146261" 14-APR-0013 16:55:18
51146263" 12-APR-0013 16:55:32.
I have no idea how the quotes or the newline appear. Is this a Toad bug? Any help would be greatly appreciated. Really urgent.
Thanks in advance
Regards

Hi Harry,
I actually thought that the str !##! was causing the problem. Actually my original export has some new lines in some specific columns so I can't keep the new line as my line terminator and hence I kept the !##! as my terminator.
When I put the same data in a notepad and load it there is no problem at all. For e.g I just typed the following in a notepad and the data loaded just fine.
A|B|!##!
51146261|01-01-01 10:10:10 AM|!##!
51146263|01-01-01 11:11:11 AM|!##!
Its just when I load the exported file there the problem arises though I have verified the file using UNIX as well using octal dump and found no hidden characters.

Prithwish

How to have more than one condition on same column --- using SQL Loader

Hi All,
I am stuck with SQL Loader..
How do I filter records before loading in the table using when clause..
i should load data only when
field1 = 'AC' or 'VC'
field2 is NULL
i used various combinations in when clause like
a) when field1='AC' or field1='VC' and field2 = BLANKS
b) when (field1='AC') and (field2 = BLANKS )
& similar...
In all the cases I tried I could not implement OR condition with field1 and null condition with field2
but my main concern is can we use OR or IS NULL things in when clause of SQL Loader..
is it possible to check this anywhere??
any alternate solution u could suggest??
Thanks

Ok I'll try that, although I did try it earlier when I had iTunes 5.xx loaded, I think.
As to size of playlists, I have a master (900 songs) that defines what will fit onto the ipod , I then generate all the others as subsets of the master (not of the library)- hence I know they will all fit
Can you also clarify something for me: the dialogue box we are discussing is intended, I think, so that one can set the automatic synching of certain playlists between the PC & the ipod. Is that the only way one can select other playlists to go to the ipod - i.e. as static once-offs, not synchronised ?
Apple' docs, I think, are poor in this regard - they assume most ipods are bigger then the users song library and they gloss over the details of this alternate mode of playlist synching.
Thanks - Nick

How to handle Multiple date formats for the same date field in SQL*Loader

Dear All,
I got a requirement where I need to get data from a text file and insert the same into oracle table.
I am using SQL*Loader to populate the data from the text file into my table.
The file has one field where I am expecting date date data in multiple formats, like dd/mon/yyyy, yyyy/dd/mon, yyyy/mon/dd, ,mm/dd/yyyy, mon/dd/yyyy.
While using SQL*Loader, I can see Loading is failing for records where we have formats like yyyy/dd/mon, yyyy/mon/dd, mon/dd/yyyy.
Is there any way in SQL*Loader where we can mention all these date formats so that this date data should go smoothly into the underlying date column in the table.
Appreciate your response on this.
Thanks,
Madhu K.

The point being made was, are you sure that you can uniquely identify a date format from the value you receieve? Are you sure that the data stored is only of a particular limited set of formats?
e.g. if you had a value of '07/08/03' how do you know what format that is?
It could be...
7th August 2003 (thus assuming it's DD/MM/RR format)
or
8th July 2003 (thus assuming it's MM/DD/RR format)
or
3rd August 2007 (thus assuming it's RR/MM/DD format)
or
8th March 2007 (thus assuming it's RR/DD/MM format)
or even more obscurely...
3rd July 2008 (MM/RR/DD)
or
7th March 2008 (DD/RR/MM)
Do you have any information to tell you what formats are valid that would allow you to be specific and know what date format is meant?
This is a classic example of why dates should be stored on the database using DATE datatype and not VARCHAR2. It can lead to corruption of data, especially if the date can be entered in any format a user wishes.

Loading huge file with Sql-Loader from Java

Hi,
I have a csv file with aprox. 3 and a half million records.
I load this data with sqlldr from within java like this:
           String command = "sqlldr userid=" + user + "/" + pass
                    + "@" + service + " control='" + ctlFile + "'";
            System.out.println(command);
            if (System.getProperty("os.name").contains("Windows")) {
                p = Runtime.getRuntime().exec("cmd /C " + command);
            } else {
                p = Runtime.getRuntime().exec("sh -c " + command);
            }it does what I want to, load the data to a certain table, BUT it takes too much time, Is there a faster way to load data to an oracle db from within java?
Thanks, any advice is very welcome

Sql@loader-704 and ORA-12154: error messages when trying to load data with SQL Loader

I have a data base with two tables that is used by Apex 4.2. One table has 800,000 records . The other has 7 million records
The client recently upgraded from Apex 3.2 to Apex 4.2 . We exported/imported the data to the new location with no problems
The source of the data is an old mainframe system; I needed to make changes to the source data and then load the tables.
The first time I loaded the data i did it from a command line with SQL loader
Now when I try to load the data I get this message:
sql@loader-704 Internal error: ulconnect OCISERVERATTACH
ORA-12154: tns:could not resolve the connect identifier specified
I've searched for postings on these error message and they all seem to say that SQL Ldr can't find my TNSNAMES file.
I am able to connect and load data with SQL Developer; so SQL developer is able to find the TNSNAMES file
However SQL Developer will not let me load a file this big
I have also tried to load the file within Apex (SQL Workshop/ Utilities) but again, the file is too big.
So it seems like SQL Loader is the only option
I did find one post online that said to set an environment variable with the path to the TNSNAMES file, but that didn't work..
Not sure what else to try or where to look
thanks

Hi,
You must have more than one tnsnames file or multiple installations of oracle. What i suggest you do (as I'm sure will be mentioned in ed's link that you were already pointed at) is the following (* i assume you are on windows?)
open a command prompt
set TNS_ADMIN=PATH_TO_DIRECTOT_THAT_CONTAINS_CORRECT_TNSNAMES_FILE (i.e. something like set TNS_ADMIN=c:\oracle\network\admin)
This will tell oracle use the config files you find here and no others
then try sqlldr user/pass@db (in the same dos window)
see if that connects and let us know.
Cheers,
Harry

You are right. The issue was of insufficient privileges. The table did not have all the necessary grants provided.

Comparison of Data Loading techniques - Sql Loader & External Tables

Below are 2 techniques using which the data can be loaded from Flat files to oracle tables.
1)     SQL Loader:
a.     Place the flat file( .txt or .csv) on the desired Location.
b.     Create a control file
Load Data
Infile "Mytextfile.txt" (-- file containing table data , specify paths correctly, it could be .csv as well)
Append or Truncate (-- based on requirement) into oracle tablename
Separated by "," (or the delimiter we use in input file) optionally enclosed by
(Field1, field2, field3 etc)
c.     Now run sqlldr utility of oracle on sql command prompt as
sqlldr username/password .CTL filename
d.     The data can be verified by selecting the data from the table.
Select * from oracle_table;
2)     External Table:
a.     Place the flat file (.txt or .csv) on the desired location.
abc.csv
1,one,first
2,two,second
3,three,third
4,four,fourth
b.     Create a directory
create or replace directory ext_dir as '/home/rene/ext_dir'; -- path where the source file is kept
c.     After granting appropriate permissions to the user, we can create external table like below.
create table ext_table_csv (
i Number,
n Varchar2(20),

External tables feature is a complement to existing SQL*Loader functionality.
It allows you to –
•     Access data in external sources as if it were in a table in the database.
•     Merge a flat file with an existing table in one statement.
•     Sort a flat file on the way into a table you want compressed nicely
•     Do a parallel direct path load -- without splitting up the input file, writing
Shortcomings:
•     External tables are read-only.
•     No data manipulation language (DML) operations or index creation is allowed on an external table.
Using Sql Loader You can –
•     Load the data from a stored procedure or trigger (insert is not sqlldr)
•     Do multi-table inserts
•     Flow the data through a pipelined plsql function for cleansing/transformation
Comparison for data loading
To make the loading operation faster, the degree of parallelism can be set to any number, e.g 4
So, when you created the external table, the database will divide the file to be read by four processes running in parallel. This parallelism happens automatically, with no additional effort on your part, and is really quite convenient. To parallelize this load using SQL*Loader, you would have had to manually divide your input file into multiple smaller files.
Conclusion:
SQL*Loader may be the better choice in data loading situations that require additional indexing of the staging table. However, we can always copy the data from external tables to Oracle Tables using DB links.
