Example Loading Data from a Fixed Width File

Load a Fixed-Width File into a New Table

This provides an example using DBMS_CLOUD.CREATE_EXTERNAL_TABLE to load data from a fixed-width source file to an external table.

For this example, the fixed-width source file has the following data:

  1. From the console, select the compartment for your Autonomous Database, and then select the link to your Autonomous Database to open the console.


    These steps are shown using Database Actions to execute the PL/SQL code, and query the data. These actions can be performed from any SQL connection, connecting to the Autonomous Database as a user with the proper privileges.
  2. On the Autonomous Database Details page click Database Actions.
  3. Within the Development section of the Database Actions Launchpad, select the SQL tile.
  4. Within the SQL Worksheet, enter and execute the following code:
                 table_name      => '<YOUR_TABLE_NAME>'
    ,            credential_name => '<YOUR_CREDENTIAL_NAME>'
    ,            file_uri_list   => '<YOUR_ORACLE_OBJECT_STORE_URL>'
    ,            format          => json_object('trimspaces' value 'rtrim','skipheaders' value '1', 'dateformat' value 'YYYYMMDD')
    ,            field_list      => 'object_id      (1:3)   char
                                   , object_name    (4:14)  char
                                   , object_type    (15:39)  char

                                   , last_ddl_time  (54:61)  date
                                   , status         (62:71)'
    ,            column_list     => 'object_id      number
                                   , object_name    varchar2(30)
