How to Install SQL Loader on Windows?

SQL Loader is a utility tool that is used to load or transfer data from external files(also known as Flat files) to Oracle databases and tables. These external files have extensions of .txt or .csv. It is a program that is used to import data into an Oracle database from external files. It is efficient and can handle large amounts of data and read from various formats such as delimited text and fixed-width files. It also gives the user control through configuration files and provides log files for tracking the loading process. You don’t need to install SQL Loader separately because it comes with Oracle Database as a command-line tool.
