Variables in Aster Topic by Robert Suhada 01 Oct 2014 variables aster

I’m trying to find out if there are variables in Aster SQL… there are in postgres but it seems this is not supported in Aster?

 

I’d need something like

 

Declare x bigint := 100;

 

Select * from my_table where y>x;

 

 

Alternative is to store the value in a tiny table, but maybe there is a nicer option?
