Hello all,
I have a table of data that is very large (502 columns) and whenever I
query it, I only query on up to 4 columns and on average only 20 fields
are returned. I've come up with a way to increase the speed of the
queries. I could could put the 20 fields that are searched and returned
into a separate table and then link them by a unique id. Sounds
easy......but I'm stuck on something.
I am dealing with about 1 million records per day.
One option is to put a sequence on the tables, but dealing with so many
records I'd have to use a BIGINT and with a ceiling of
9223372036854775807 it seems to me that numbers this large might slow
down the query process. I realize it would take quite a while to get to
this point, but would like other's opinions.
Another option is that I have 3 fields that when combine, make each
record unique. Is there some way I can combine these dynamically and
then use "views" of them to reference my records and display them from
the larger table.
I realize this is very confusing, please get back with me if I should
elaborate on something.
Any help is appreciated.
Thanks,
Kevin
