QUESTION POSED ON: 15 June 2007
I am a newbie for the Oracle platform; for the last five years we've been using SQL Server, and now we switched to Oracle. Coming to the point, we have an application in which we have to import a text file (delimited with commas) to an Oracle table via our application. Our application tool is PL/SQL. So is there any way to import a text file in Oracle via coding? Earlier we were using BCP (bulk insert utility) in SQL Server. Please suggest an alternative method. Thanks.

You already know about SQL Server's BCP utility. Oracle's similar utility is called SQL*Loader. SQL*Loader will load the contents of a text file into an Oracle table. Oracle extended this utility with something called External Tables. With External Tables, you can access a text file with SQL commands just as if it were an actual table. External Tables uses the SQL*Loader engine before passing the data to the SQL engine.
