SQL*Loader provides the following methods to load data:
Conventional Path Loads, Direct Path Loads, External Table
Loads
Conventional Path Loads: During conventional path loads,
the input records are parsed according to the field
specifications, and each data field is copied to its
corresponding bind array. When the bind array is full (or
no more data is left to read), an array insert is executed.
Direct Path Loads: A direct path load parses the input
records according to the field specifications, converts the
input field data to the column datatype, and builds a
column array. The column array is passed to a block
formatter, which creates data blocks in Oracle database
block format. The newly formatted database blocks are
written directly to the database, bypassing most RDBMS
processing. Direct path load is much faster than
conventional path load, but entails several restrictions.
External Table Loads: An external table load creates an
external table for data in a data file and executes INSERT
statements to insert the data from the data file into the
target table.
