Conventional Path Loads
SQL*Loader stores LOB fields after a bind array insert is done. Thus, if there are any
errors in processing the LOB field (for example, the LOBFILE could not be found), the
LOB field is left empty. Note also that because LOB data is loaded after the array insert
has been performed, BEFORE and AFTER row triggers may not work as expected for
LOB columns. This is because the triggers fire before SQL*Loader has a chance to load
the LOB contents into the column. For instance, suppose you are loading a LOB
column, C1, with data and that you want a BEFORE row trigger to examine the
contents of this LOB column and derive a value to be loaded for some other column,
C2, based on its examination. This is not possible because the LOB contents will not
have been loaded at the time the trigger fires.

Learning to write and speak a foreign language correctly requires having somebody to correct your grammar and usage errors.
Otherwise you may learn a substandard version of the language with deep-rooter mistakes and incorrect usages that are hard to get rid of.
A popular and tried-and-true way to learn languages involves writing texts in a foreign language on a daily basis and reading them aloud to a native speaker, who will correct any mistakes.
Native speakers or language professionals will review your text and correct all errors of style or grammar free of charge.
You can also request a sound recording of the spoken version of your corrected text that will let you hear the subtleties of pronunciation by a native speaker.
