-- NAME
-- ulcase8.ctl - SQL*Loader Case Study 8: Loading Partitioned Tables
--
-- DESCRIPTION
-- This case study demonstrates the following:
-- Partitioning of data.
--
-- Explicitly defined field positions and datatypes.
--
-- Loading data using the fixed-record-length option. 
--
-- TO RUN THIS CASE STUDY:
-- 1. Before executing this control file, log in to SQL*Plus as
--    scott/tiger. Enter @ulcase8 to execute the SQL script for
--    this case study. This prepares and populates tables and
--    then returns you to the system prompt.
--      
-- 2. At the system prompt, invoke the case study as follows:
-- sqlldr USERID=scott/tiger CONTROL=ulcase8.ctl LOG=ulcase8.log
--
-- NOTES ABOUT THIS CONTROL FILE
-- This control file loads the lineitem table with fixed-length
-- records, partitioning the data according to shipment date.
--
-- The INFILE clause specifies that each record in the datafile is 
-- of fixed length (129 bytes in this example).
--
-- The PARTITION clause identifies the column name and location of the
-- data in the datafile to be loaded into each column.
--
