Alternative Ways to Specify SQL*Loader Parameters

If the length of the command line exceeds the maximum line size for your system, then you can put certain command-line parameters in the control file by using the OPTIONS clause.

You can also group parameters together in a parameter file. You specify the name of this file on the command line using the PARFILE parameter when you start SQL*Loader.

These alternative ways of specifying parameters are useful when you often use the same parameters with the same values.

Parameter values specified on the command line override parameter values specified in either a parameter file or in the OPTIONS clause.
