When using COUNT in SUMMARIZE, there is no reason why COUNT would have a parameter, because the COUNT of any attribute is the same for all attributes.

Here's an example of using COUNT in SUMMARIZE:
[code]SUMMARIZE myvar1 BY {x} ADD (COUNT() AS n)[/code]

CAN I USE WHERE WITH SUMMARIZE?

Me too I have some trouble with the use of group by with tutorial d.

Is it possible to define group by in Rel? If yes, then what is the correct syntax?
