Please note: the command line parameters can be specified by the location or keyword.
. The former example is 'sqlload
Scott/tiger foo '; the next example is 'sqlldr control = foo
Userid = scott/tiger '. The specified location parameter must be earlier
However, it cannot be later than the parameter specified by the keyword. For example,
'Sqlldr scott/tiger control = foo logfile = log' is allowed,
'Sqlldr scott/tiger control = foo log' is not allowed, even if
The location of the 'log' parameter is correct.
