Re: proc installed on win95, oracle database on hp box

Hi Chip,

    What I am about to utter is rank heresy, but .... for small tables keys, primary or otherwise, can actually reduce performance. In a properly tuned database Oracle will probably be reading 64KB at a time from disk. The amount of time required to read in the index (which tends to be one Oracle block at a time) and then read the data is greater than the time required to read the data and select the desired row from RAM.

    Many lookup and reference tables fall into the less than 64KB category, for example, a lookup table for US state names and postal abbreviations.

    Incidentally, keys are not necessary to uniquely identify records provided that the contents uniquely identify the record.

regards

Jerry Gitomer
