Rajan, I'll make the assumption that there are no DB links between the instances (I'm making the assumption that a database and an instance are equal). Under this situation log in to the target instance and use the 'copy' command in SQL*Plus. The syntax is: COPY FROM <USERNAME>/<PASSWORD>@<DATABASE_NAME> - CREATE/APPEND <TABLE_NAME> - USING SELECT <COLUMN1>, <COLUMN2>,<ETC...> - FROM <TABLE_NAME_AT_REMOTE>; Note: Make sure to use the dash ("-") as a line continuation character. Otherwise a carriage return executes the statement. Dick Goulet ____________________Reply Separator____________________ Author: "andrey" <[EMAIL PROTECTED]> Date: 3/13/2001 1:30 AM Dear list !
