-- Copyright (c) 1991, 2004 Oracle. All rights reserved. -- 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. -- LOAD DATA INFILE ‘ulcase8.dat‘ "fix 129" BADFILE ‘ulcase8.bad‘ TRUNCATE INTO TABLE lineitem PARTITION (ship_q1) (l_orderkey position (1:6) char, l_partkey position (7:11) char, l_suppkey position (12:15) char, l_linenumber position (16:16) char, l_quantity position (17:18) char, l_extendedprice position (19:26) char, l_discount position (27:29) char, l_tax position (30:32) char, l_returnflag position (33:33) char, l_linestatus position (34:34) char, l_shipdate position (35:43) char, l_commitdate position (44:52) char, l_receiptdate position (53:61) char, l_shipinstruct position (62:78) char, l_shipmode position (79:85) char, l_comment position (86:128) char)
