Re: 1600 Column limit..

we have to have all of that information per shelf.. so we have the columns with the information then each row is a
differentshelf.. which to start with there are 400.. which could grow to upwards to any number.. but I did split all of
thisup into seperate tables..

Seems like a more effective layout would be

create table tracking (
  i_slot int4,
  i_port int4,
  i_item int4 );

maybe i'm missing somthing, but a 1600 row table is tiny, a 1600 column
table would be very difficult to manage, and poor design.
