    Exclamation HELP-Load Text File into Oracle Table - PL/SQL Script

    It seems simple enough, but it's not working for me. If anyone can help with the syntax to make this work, i'd really appreciate it:

    File(s):
    "DataExtract-20051231.txt"
    "DataExtract-20051222.txt"
    "DataExtract-20051208.txt"

    Contents of a file could be:

    34 John A.Smith jasmith Engineer
    23 Jim P.Johnson jpjohnson Developer
    43 Bob D.User bduser King


    Lets say

    The First 4 characters are: Age
    Next 5: First name
    Next 2: Middle Initial
    Next 8: Last name
    Next 10: Username
    Last 9: Title.

    I have a table... my_table with the fields:
    AGE
    F_NAME
    M_NAME
    L_NAME
    U_NAME
    TITLE


    How do I put the data from all of these data files into the table using a PL/SQL script? Any ideas?

    Thank you!

    This is the only READ_FILE procedure that compiled.


    CREATE OR REPLACE PROCEDURE READ_FILE
    (PI_DIRECTORY IN VARCHAR2,
    PI_FILE_NAME IN VARCHAR2)
    AS
    V_File_handle UTL_FILE.FILE_TYPE;
    V_FILE_Line VARCHAR2(906);
    BEGIN
    V_File_handle :=
    UTL_FILE.FOPEN(PI_DIRECTORY, PI_FILE_NAME, 'R');
    LOOP
    UTL_FILE.GET_LINE( V_File_handle , v_file_line);
    DBMS_OUTPUT.PUT_LINE(v_file_line);
    END LOOP;
    EXCEPTION
    WHEN NO_DATA_FOUND
    THEN UTL_FILE.FCLOSE( V_File_handle );
    END;

    /

    Apparently, here is how to create a directory and set the permissions:

    In order to create a directory you, (the database user), should have the following privileges:

    CREATE ANY DIRECTORY.

    CREATE OR REPLACE DIRECTORY test_files AS ‘E:\oracleWork’;

    By default, you do get the READ WRITE privileges on this object. However, if you wish to assign a READ WRITE privilege to another user you can GRANT the necessary privileges as follows:

    GRANT READ ON DIRECTORY test_files TO PUBLIC;

    This is how to use a view to see the data from the file, but not load it:

    Consider a data file "emp_load.dat"

    This file emp_load.dat should be located in the physical directory "E:\oracleWork" identified by the directory object TEST_FILES.

    The DDL to create the external table will be as follows:

    CREATE TABLE emp_external
    ( emp_id NUMBER(4)
    , ename VARCHAR2(12)
    , job VARCHAR2(12)
    , mgr_id NUMBER(4)
    , hiredate DATE
    , salary NUMBER(8)
    , comm NUMBER(8)
    , dept_id NUMBER(2))
    ORGANIZATION EXTERNAL
    (TYPE oracle_loader
    DEFAULT DIRECTORY TEST_FILES
    ACCESS PARAMETERS (records delimited BY newline
    fields terminated BY ',')
    LOCATION ('emp_load.dat')
    );

    To view the data, all you have to do is query the table like a regular table viz:

    SELECT * FROM emp_external;
