I have tried the example from http://code.kx.com/wiki/JB:KdbplusForMortals/segments#1.4.3_Multiple_Segmented_Tables
But I don’t understand what is the date variable when a segmented table loaded? It seems the date variable contains dates from all segments but in ascending order. Why dates are reapeted not unique? Even if I delete this variable from the context, tables contains valid date columns, but select command if the date variable is used doesn’t work any more.
