RE: Sqlldr versus inserts

John

Questions that you should look at :

            How much of data massaging is done to the raw data - at this time once it is loaded via sqlldr

            What is the source of data. Is there any optimization possible in getting the source via say pipes or queues

In the end if there is a lot of sql that is involved then you are better off using sqlldr and then plsql.

If not then java should work fine.

Subject: Sqlldr versus inserts  

We currently load large amounts of data into a table using sqlldr which is run from a unix script initiated from a java stored procedure.

The application designers want to eliminate the script and load the data directly using java and jdbc, which I presume will mean using insert statements.  

Sound like a bad idea to me from a performance point of view, but am I correct? If not using sqllldr what oprions are there to read a flat file and inseet the data. Will external files give the same performance as sqlldr?
