![]() Moreover, REPLACE using delete command, so any delete trigger will fire unless DELETE CASCADE has been specified for the table itself. SQL*Loader will not update the existing rows. REPLACE replaces the table, not individual rows or a set of rows. It is used for better performance compared to REPLACE. TRUNCATE | REPLACE : TRUNCATE is used to truncate the table before loading the new data to it. You must have the “SELECT” privilege on the target table for using APPEND. APPEND : If the data already exists in the table, Oracle SQL*Loader will add the new rows otherwise, the rows will be inserted. DATE “mm/dd/YYYY” : The date format that match CSV file data column. Not all operating systems support multithreading. If you have multiple CPU systems, this parameter will be enabled (set to true) by default, and be aware that multithreading functionality is operating system-dependent. This parameter is available only for direct path loads. MULTITHREADING=false : The default is true on multiple-CPU systems and false on single-CPU systems. A value of false specifies a conventional path load. DIRECT=true : A value of true specifies a direct path load. ![]() PARALLEL=false : Specifies that loads can operate in multiple concurrent sessions to load data into the same table. SKIP=1 : Skip the first line of CSV, as it contains a header.

You have it somewhere on the server or locally in your machine doesn’t matter for now. Consider that you have an external system that is extracted some data into a CSV file comma separated format. ![]()
