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.badTRUNCATEINTO TABLE lineitemPARTITION (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)
