SQL LOADER "LOGICAL COMMIT"

Hello ,
After each successful execution of sql loader ,it implicitly commits the underlying transactions .
Why this implicit commit is happening and Can disable this auto commit feature of sql loader ?
Thanks

Hi ,
We cannot stop the commit option in sqlloqder.
By using the ROWS parameter we can control the feature
For eg rows=200
The records will be committed after every 200 records are over only.
Thanks

SQL loader and commit

Hi,
I am trying to execute a sql loader script that populates many tables. The order of the tables in the script is very important because the table of the last table has a constraint with the first table of the script. So I need that sqlloader executes a commit after the filling of the first tables because if sql loader executes the script simply as it is written the last tables launches an error because the constraint is violated (the last table sees the first one empty).
How can I force a commit after a filling in sql loader?
The sctructure of the tables was not defined by me so I must not modify it (constraint included).
Thanks, bye bye.

Hi,
If you have to enable/disable manually the constraints you can execute:
DECLARE
v_ds_action VARCHAR2(7);
BEGIN
v_ds_action := 'DISABLE';
    FOR reg IN (SELECT * FROM user_constraints uc WHERE uc.constraint_type = 'R') LOOP
    EXECUTE IMMEDIATE 'ALTER TABLE ' || reg.table_name || ' ' ||
                      v_ds_action || ' CONSTRAINT ' || reg.constraint_name;
END LOOP;
FOR reg IN (SELECT * FROM user_constraints uc WHERE uc.constraint_type = 'C') LOOP
    EXECUTE IMMEDIATE 'ALTER TABLE ' || reg.table_name || ' ' ||
                      v_ds_action || ' CONSTRAINT ' || reg.constraint_name;
END LOOP;
FOR reg IN (SELECT * FROM user_constraints uc WHERE uc.constraint_type = 'U') LOOP
    EXECUTE IMMEDIATE 'ALTER TABLE ' || reg.table_name || ' ' ||
                      v_ds_action || ' CONSTRAINT ' || reg.constraint_name;
END LOOP;
FOR reg IN (SELECT * FROM user_constraints uc WHERE uc.constraint_type = 'P') LOOP
    EXECUTE IMMEDIATE 'ALTER TABLE ' || reg.table_name || ' ' ||
                      v_ds_action || ' CONSTRAINT ' || reg.constraint_name;
END LOOP;
END;
DECLARE
v_ds_action VARCHAR2(7);
BEGIN
v_ds_action := 'ENABLE';
FOR reg IN (SELECT * FROM user_constraints uc WHERE uc.constraint_type = 'P') LOOP
    EXECUTE IMMEDIATE 'ALTER TABLE ' || reg.table_name || ' ' ||

Help Required with PL/SQL loading logic

Hi All,
We have a simple pl/sql code which does loading(insertions) of records into the table. This pl/sql code actually refers to an translation website URL(microsoft based) and inserts the translated text into our table. What happens is sometimes this URL gets blocked out due to some issue. So we are forced to restart our entire operation of loading once again. Actually we have a commit at the end(outside the loop). on the other hand we cant keep commit inside the loop as it may pose an overhead to performance since its commiting once every insert happens.
What we are expecting is something like this. Say we have 10,000 records. the loading fails at 5500 record. next time when we start again we want to start from 5501 record and NOT from beginning. In informatica kind of ETL tools we have an option to do this. However not sure if we can do this through PL/SQL.
we thought of keeping counter variable and keep it incrementing for each and every insert happens. but before doing this we have to order by our table according to primary key. This is taking huge amount of time since the table is very big.
can you please tell any alternative to this?
Regards,
Paul

If I understand correctly, you are doing something as follows:
// process a defined data set
for c in (select .. some data... )
loop
    // translate the data (via a web service call)
    Translate( c, translatedOutput )
    // insert the translated data
    insert into some_table translatedOutput
end loop
commitIn principle, nothing wrong with this approach. And yes, committing inside the loop for every x number of rows will increase the complexity of code and could perhaps violate ANSI SQL standards of fetching across commits.
A better approach would be to consider parallelising this process. Run multiple copies of that code - but provide each copy of the code with a small and unique data set to process. So instead of doing 10,000 rows in serial, you schedule a 100 jobs and give each a unique set of a 100 rows to translate.
Let's say your job queue size is set to 20. This means up to 20 of these processes will run in parallel. Should one fail, the job manager will automatically reschedule it for execution (up to 16 times after which it will be marked as broken).
So not only does this type of approach enables you spread the processing load, it also enables you to scale your processing (you can handle much larger data volumes like this, and more powerful server h/w will enable you to use more parallel processes). In addition, restart is automated courtesy of the Oracle job manager.
Compare this type approach with committing inside a loop.. The latter buys you what ito flexibility and performance and scalability? Nothing really - it only makes the process a lot more complex as it needs to be able to correctly restart after a failure. You will not be able to process bigger volumes of data. You will not be able to increase existing performance.
One needs to carefully consider the approach used to processing data - serialisation is inherently limited. Restarting serialised processes is difficult and complex.

SQL LOADER message : Point de validation COMMIT atteint - nombre d'enreg

Hello
I am loading a csv file into an oracle table via SQL LOADER
Each time i invoke it i get the folowing message :

Substitution for logical OR usage in control file of sql loader

Hi,
can anyone suggest me a substituion method to use the functionality of logical OR in control file developed for sql loader.
Ex:
load data
append
into table ABC
when (1:2) = 'AD'
--AND ((27:28)= '01' OR (27:28)= '02')
AND (1222:1222) = '1'
trailing nullcols
Note: condition commented in the above example need to be replaced.
one way of doing it can be splitting blocks for each condition.
Then it will look like:
load data
append
into table ABC
when (1:2) = 'AD'
AND (27:28)= '01'
AND (1222:1222) = '1'
trailing nullcols
into table ABC
when (1:2) = 'AD'
AND (27:28)= '02'
AND (1222:1222) = '1'
trailing nullcols
So, i'm looking for a better way than this, as i cannot work with the above
splitting logic because i'm dealing with lot many conditions.
Thanx inadvance

SQL Loader with decimal commas

Dear All,
I am loading data for a German client and the delivered files contain numeric data with decimal commas. For example 123,5 instead of 123.5
I've been googling like mad on this one and there is a lot of chatter about setting NLS_LANG and/or NLS_NUMERIC_CHARACTERS but none of this seems to work in the SQL Loader environment.
I imagine that I will end up cobbling together a complicated thing with TO_NUMBER or with another function but I really can't believe that SQL Loader doesn't have a simple switch to flip from point to comma.
Or have I overlooked something?
Any tips would be a great help.
Regards,
Alan Searle

I am on a client's PC and don't have access to administrative settings.
And also, I cannot be sure that whoever runs the load function in the future will check this.
It is therefore important that I find a way to set this in SQL Loader without any other dependencies.
I think I will probably end up processing it as a string and then translating it to numeric. But this seems like a sledge hammer to crack a nut.
Regards and thanks,
Alan

Extracting Multiple Logical Records through sql loader

Hello gurus,
I have few questions regarding the sql loader. I m totally new to this i have never used, this is the first time i m using
1.
How do i find the position number of the charcter or a number ? do i need to physically count the position ? is ther any specific way of counting or use textpad to do that ?
I know it sounds like silly question... but i wanted to know if there is any better way of doing it
2.
example data
1119 Smith      1120 Yvonne
1121 Albert     1130 Thomas
The following control file extracts the logical records:
INTO TABLE emp
     (empno POSITION(1:4) INTEGER EXTERNAL,
      ename POSITION(6:15) CHAR)
INTO TABLE emp
     (empno POSITION(17:20) INTEGER EXTERNAL,
      ename POSITION(21:30) CHAR)---
2. Can you please expalin me what does the "null if deptno = blanks " ?
deptno POSITION(1:2) INTEGER EXTERNAL(2)
              NULLIF deptno=BLANKS,I really appriciate it ~
Thanks

Hi,
The NULLIF means load blanks as NULL
http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/ldr_field_list.htm#sthref1129
Not sure I understand your first question. You must of course know the format of the file, TextPad could be an ok tool for determining that format for a fixed column width file.

Peter

I parallelize the use of SQL*Loader.But it always commit per 89 rows

I parallelize the use of SQL*Loader. But it always commit per 89 rows. How can I set Commit Row Number?

enlarge the BINDSIZE= and ROWS= option or better use DIRECT=TRUE

SQL Loader and weird source file structure

I am familiar with using SQL Loader to process comma or tab delimited text files into proper table data. But how do you process "positionally delimited" files?!
I mean, I have a text file which looks like this:
Item A
---attribute1
---attribute2
---attribute3
---attribute4
Item B
---attribute1
---attribute2
---attribute3
---attribute4
Item C
---attribute1
---attribute2
---attribute3
---attribute4
And so on. How do I tell SQL Loader, 'rows 1, 6 and 11 are the first column in the table; rows 2, 7 and 12 and the second column; rows 3, 8, 13 are the third and so on? I want to end up with data in the form
Item A Attribute1 Attribute2 Attribute3 Attribute 4
Item B Attribute1 Attribute2 Attribute3 Attribute 4
Item C Attribute1 Attribute2 Attribute3 Attribute 4
Is such a thing even possible with SQL Loader?

If your data is exactly in that format like in sample provided by Enrique, you can try to play with that certain data pattern. Again, based on previous example:

SQL Loader and Batch ID

Hi All,
In our application, we are allowing user to upload data using excel sheet in UI.
We are using PHP script in UI and using SQL Loader to load data from excel sheet to temp_table.
The temp_table has a primary key.
Here my question is , Is there any way to put some batch id for every upload in that table in automatic way ?
so that we can easily extract the data by using batch id
we are using Oracle 11g.

All that does is load a constant value, in which case you might as well just use constant 815 in your control file. If you want to automatically increment the value for each batch, then you need to use a different method.
Please see the example below. Prior to each data load, it loads the next value of the sequence into a separate table, then selects that value during the data load. Note that a SQL*Loader expression that uses select must be enclosed within parentheses within the double quotes.

SQL Loader and INSERT Trigger

I have problem and your help to solve it would be very much appreciated.
I am uploading a text file with SQL Loader into a table. Since I used APPEND option in the Loader, I don't want records to be duplicated. So, I wrote a "BEFORE INSERT .. FOR EACH ROW" trigger to check whether that row already exists or not.
For example, let us consider a table TEST as follows.
Fld1     NUMBER(2);
Fld2     VARCHAR2(10);
Fld3     VARCHAR2(10);
I have a trigger on this table.
CREATE OR REPLACE TRIGGER Trg_Bef_Insert_Test
BEFORE INSERT ON Test FOR EACH ROW
DECLARE
vCount NUMBER(2);
DuplicateRow EXCEPTION;
BEGIN
SELECT Count(*) INTO vCount FROM Test
     WHERE fld1 || fld2 || fld3 = :new.fld1 || :new.fld2 || :new.fld3;
IF vCount > 0 THEN
     RAISE DuplicateRow;
END IF;
EXCEPTION
WHEN DuplicateRow THEN
     Raise_Application_Error (-20001,'Record already exists');
WHEN OTHERS THEN
     DBMS_OUTPUT.PUT_LINE('ERROR : ' || SQLCODE || '; ' || SUBSTR(SQLERRM, 1, 150));
END;
Please refer to the following SQL statements which I executed in the SQL Plus.
SQL> insert into test values (1,'one','first');
1 row created.
SQL> insert into test values (1,'one','first');
insert into test values (1,'one','first')
ERROR at line 1:
ORA-20001: Record already exists
ORA-06512: at "CAMELLIA.TRG_TEST", line 13
ORA-04088: error during execution of trigger 'CAMELLIA.TRG_TEST'
Would anyone tell me why do errors -6512 and -4088 occur ?
Also, if you have any other suggestion to handle this situation, please let me know.
By the way, I am using Oracle 8.1.7.
Thank you.

There are a few things wrong here, but you should really use a unique constraint for this.
SQL> create table t (a number, b number, c number,
2      constraint uk unique (a, b, c));
Table created.Here's an example data file with 12 records three of which are duplicates.
1,2,3
3,4,5
6,7,8
3,2,1
5,5,5
3,4,5
3,2,1
1,1,1
2,2,2
6,7,8
8,8,8
9,9,9And a control file
load data
infile 'in.dat'
append
into table t
fields terminated by ',' optionally enclosed by '"'
(a, b, c)Running it with sql loader, inserts the nine records, outputs the three duplicates to a .bad file and logs all the errors in the .log file. No need for triggers or any code.
