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 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.

  • 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).

  • SQL Loader and table views

    I am having a problem updating a large partitioned table through it's appropriate view. Here is the loader file
    LOAD DATA               
    INSERT INTO TABLE test.example               
         (      PROGRAM POSITION(1:4) CHAR,
              DWING_NUMBER     POSITION(6:32) CHAR,
              LAST_ISSUED_REVISION     POSITION(34:35) CHAR,
              TEMP_NUMBER     POSITION(37:43) CHAR,
              CONFIGURATION_ITEM     POSITION(45:45) CHAR,
              LOCATION_CODE     POSITION(47:47) CHAR
    It generates this error:
    SQL*Loader-951: Error calling once/load initialization
    ORA-26018: Column PROGRAM in table test.example does not exist
    There are a few considerations that go along with this, and I am developing a strong disdain for the 2 dba's that are involved. First, this view accesses a large partitioned table, all according to "PROGRAM". Secondly, PROGRAM is called PROG_ID in the main table. I didn't think this was an issue at first, but it seems like it might be part of the problem I'm having. We're running Oracle 9.2.0 here. Any helpful replies will be greatly appreciated. Thanks.

    This is what the view looks like:
    Column / Data Type / Null? / Updatable
    PROGRAM VARCHAR(10) N y
    DWING_NUMBER VARCHAR(28) N y
    LAST_ISSUED_REVISION VARCHAR(2) Y y
    TEMP_NUMBER VARCHAR(7) Y y
    CONFIGURATION_ITEM VARCHAR(1) Y y
    LOCATION_CODE VARCHAR(1) Y y
    The main table that this view grabs data from is identical, except for the fact that PROGAM is PROG_ID. I'm fairly new to doing database work, so if the answer is trivial please spare my self esteem.

  • Using SQL Loader to insert data based on conditionally statements

    I would like to use sql loader to insert records from a single text file into an Oracle database table. Sounds easy but the problem is that I need to check the existence of data in another table (Table A) before data can be loaded into Table B.
    Table A has two columns: dept_no (primary key value) and dept_name (char)
    Table B has five columns: emp_no (primary key value), dept_no (foreign key value to Table A), employee (char), job_title (char) and salary (number)
    Text File looks like this:
    Finance Jones President 10000
    HR Smith Admin 2000
    HelpDesk Jenkins Technician 3000
    Problem:
    1. I need sql loader to insert records into Table B by first checking if the first field in the file is in Table A.
    2. If value exists get it's dept_no value.
    3. If value doesn't exist discard record ( I might want to have sql loader insert a new record for this into Table A)
    4. Using value from #2, insert the value in Table B for dept_no column.
    5. Also assign a sequence value for the emp_no value in Table B.
    Any guidance is greatly appreciated.
    Thanks,

    Hello,
    I am not sure this is possible with SQL loader. I would rather use an external table based on your file.
    Then, I would use SQL to load your data into your table, based on your conditions.
    Your request is not very complicated, writing the SQL to do that will be really more simple than trying to do it with SQL loader.
    Hope it will help.

        how to read the column value from excel and insert into table.
      please help.

    < unnecessary reference to personal blog removed by moderator >
    Here are the steps:
    1) First create a directory and grant read , write , execute to the user from where you want to access the flat files and load it.
    2) Write a generic function to load PIPE delimited flat files:
    CREATE OR REPLACE FUNCTION TABLE_LOAD ( p_table in varchar2,
    p_dir in varchar2 DEFAULT ‘YOUR_DIRECTORY_NAME’,
    P_FILENAME in varchar2,
    p_ignore_headerlines IN INTEGER DEFAULT 1,
    p_delimiter in varchar2 default ‘|’,
    p_optional_enclosed in varchar2 default ‘”‘ )
    return number
    is
    – FUNCTION TABLE_LOAD
    – PURPOSE: Load the flat files i.e. only text files to Oracle
    – tables.
    – This is a generic function which can be used for
    – importing any text flat files to oracle database.
    – PARAMETERS:
    – P_TABLE
    – Pass name of the table for which import has to be done.
    – P_DIR
    – Name of the directory where the file is been placed.
    – Note: The grant has to be given for the user to the directory
    – before executing the function
    – P_FILENAME
    – The name of the flat file(a text file)
    – P_IGNORE_HEADERLINES
    – By default we are passing 1 to skip the first line of the file
    – which are headers on the Flat files.
    – P_DELIMITER
    – Dafault “|” pipe is been passed.
    – P_OPTIONAL_ENCLOSED
    – Optionally enclosed by ‘ ” ‘ are been ignored.

    commit;
    RETURN L_ROWCOUNT;
    end TABLE_LOAD;
    Note: when you run the function then it will also modify the source flat file with timestamp , so that we can have the track like which file was loaded .
    3) Check if the user is having UTL_FILE privileges or not :
    SQL> SELECT OWNER,
    OBJECT_TYPE
    FROM ALL_OBJECTS
    WHERE OBJECT_NAME = ‘UTL_FILE’
    AND OWNER =<>;
    If the user is not having the privileges then grant “UTL_FILE” to user from SYS user:
    SQL> GRANT EXECUTE ON UTL_FILE TO <>;
    4) In the function I have used two tables like:
    import_hist table and badlog table to track the history of the load and another to check the bad log if it occurs while doing the load .
    Under the same user create an error log table to log the error out records while doing the import:
    SQL> CREATE TABLE badlog
    errm VARCHAR2(4000),
    data VARCHAR2(4000) ,
    error_date TIMESTAMP
    Under the same user create Load history table to log the details of the file and tables that are imported with a track of records loaded:
    SQL> create table IMPORT_HIST
    FILENAME varchar2(200),
    TABLE_NAME varchar2(200),
    NUM_OF_REC number,
    IMPORT_DATE DATE
    5) Finally run the PLSQL block and check if it is loading properly or not if not then check the badlog:
    Execute the PLSQL block to import the data from the USER:
    SQL> declare
    P_TABLE varchar2(200):=<>;
    P_DIR varchar2(200):=<>;
    P_FILENAME VARCHAR2(200):=<>;
    v_Return NUMBER;
    BEGIN
    v_Return := TABLE_LOAD(
    P_TABLE => P_TABLE,
    P_DIR => P_DIR,
    P_FILENAME => P_FILENAME,
    P_IGNORE_HEADERLINES => P_IGNORE_HEADERLINES,
    P_DELIMITER => P_DELIMITER,
    P_OPTIONAL_ENCLOSED => P_OPTIONAL_ENCLOSED
    DBMS_OUTPUT.PUT_LINE(‘v_Return = ‘ || v_Return);
    end;
    6) Once the PLSQL block is been executed then check for any error log table and also the target table if the records are been successfully imported or not.

  • How to insert into two differents tables at the same time

    Hi
    I'm newer using JDev, (version 3.1.1.2 cause the OAS seems to support just the JSP 1.0)
    and I want to insert into two differents tables at the same time using one view.
    How can I do that ?
    TIA
    Edgar

    Oracle 8i supports 'INSTEAD OF' triggers on object views so you could use a process similar to the following:
    1. Create an object view that joins your two tables. 'CREATE OR REPLACE VIEW test AS SELECT d.deptno, d.deptname, e.empname FROM DEPT d, EMP E'.
    2. Create an INSTEAD OF trigger on the view.
    3. Put code in the trigger that looks at the :NEW values being processed and determines which columns should be used to INSERT or UPDATE for each table. Crude pseudo-code might be:
    IF :NEW.deptno NOT IN (SELECT deptno FROM DEPT) THEN
    INSERT INTO dept VALUES(:NEW.deptno, :NEW.deptname);
    INSERT INTO emp VALUES (:NEW.deptno, :NEW.empname);
    ELSE
    IF :NEW.deptname IS NOT NULL THEN
    UPDATE dept SET deptname = :NEW.deptname
    WHERE deptno = :NEW.deptno;
    END IF;
    IF :NEW.empname IS NOT NULL THEN
    UPDATE emp SET empname = :NEW.empname
    WHERE deptno = :NEW.deptno;
    Try something along those lines.

  • Read data from E$ table and insert into staging table

    Hi all,
    I am a new to ODI. I want your help in understanding how to read data from an "E$" table and insert into a staging table.
    Scenario:
    Two columns in a flat file, employee id and employee name, needs to be loaded into a datastore EMP+. A check constraint is added to allow data with employee names in upper case only to be loaded into the datastore. Check control is set to flow and static. Right click on the datastore, select control and then check. The rows that have violated the check constraint are kept in E$_EMP+ table.
    Problem:
    Issue is that I want to read the data from the E$_EMP+ table and transform the employee name into uppercase and move the corrected data from E$_EMP+ into EMP+. Please advise me on how to automatically handle "soft" exceptions in ODI.
    Thank you

    Hi Himanshu,
    I have tried the approach you suggested already. That works. However, the scenario I described was very basic. Based on the error logged into the E$_EMP table, I will have to design the interface to apply more business logic before the data is actually merged into the target table.
    Before the business logic is applied, I need to read each row from the E$EMP table first and I do not know how to read from E$EMP table.

    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.

    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.

  • Extract data from xml file and insert into another exiting xml fil

    hello,
    i am searching extract data from xml file and insert into another exiting xml file by a java program. I understood it is easy to extract data from a xml file, and how ever without creating another xml file. We want to insert the extracted data into another exiting xml file. Suggestions?
    Regards,
    Zhuozhi

    If the files are small, you can load the target file in a DOM document, insert the data from the source file and persist the DOM.
    If the files are large, you probably want to use a StAX or SAX.
