After a long time I am back on C# Corner with a new article. Today I will explain how to put Excel or text file data into an Oracle table. You can do this easily in SQL Server with a Copy (Ctrl+C) of the data from Excel then open the target table into edit mode and Paste (Ctrl+V). But this will not work in Oracle. In an Oracle database you can do it using the import command. I will show you each and every step with snapshots. Step 1: Open TOAD.
