external tables are normally fast without indexes as they rely on fs access time . on the other hand i use them exclusively for loading data in my dw. so its sure beats thetime taken by loading the time that sqlloader takes to load the data and process it. susan lam <susanzlam@xxxxxxxxx> wrote: Hi, I've a huge flat file (about 20GB) to load into a 9i database. I would like to make use of the external table feature but I do not know the usefulness of it if I cannot create any indexes on external tables. Querying on the table will be slow without the indexes. Are there other alternatives where I could make use of the external table feature and yet be able to query the table without any performance impact?
