Loading records from external file-system to DB!
I want to insert multiple records on a single query and my records are in an external file.
Please any advice for me ...
I have 2 Approach:: Please suggest which one will work effectively.
1: Using external table ... "insert into table select * from exttbl;"
2: Using SQL loder .
The answer is really where does the file reside? If it is not on the database server, external table is probably not the solution, the database needs direct access to the file in order to load it.
There is a third option that can also be used to load data into Oracle tables, that is a PL\SQL procedure that uses the procedures and functions in UTL_FILE to read an ASCII file (on the server) then convert or transform the data if necessary and load it into one or more tables.
