INSERT INTO my_table SELECT * FROM my_ext_table;For more information on External Tables, read the Oracle Utilities Guide. Part III covers External Tables.
If the text file resides on the client side, then you'll have to install Oracle Client software on the workstation. This should be OK since you were using "bcp," which requires you to install SQL Server client tools on the workstation. Once you have Oracle Client on the workstation, you can use Oracle's utility for loading text files into a table. This utility is called SQL*Loader. The document I referenced above also covers SQL*Loader in Part II. SQL*Loader can also be used on the database server in lieu of External Tables.
Either solution does essentially the same thing, as both SQL*Loader and External Tables use the same engine to read the contents of the text file.
