I would like to make a table of 20 plus columns the
majority of columns being arrays.
The following test works. The array will hold up to
five characteristics of each parameter including the unit of measurement used.
Using traditional methods I would need six columns to accomplish the same end
(Min, Max, Norm plus a unit column for each).
The downside is that the number of brackets
required increases for each succeeding column for insert and update. The last
column would comprise 48 brackets, 24 before - 24 after.
Is there a work-around for this.

create table specifications (
fluid_id int4 , Flow_Rate varchar array[5], Temperature varchar array[5], Pressure_In varchar array[5] , Pressure_Out varchar array[5] ); insert into specifications values ('1', '{25,
50, 100, gpm}', '{{100, 250, 500, DegF}}',
'{{{10, 40, 100, psi}}}', '{{{{60, 120, 150, psi}}}}' ); |
