Hi list, Can anyone advise me on creating an aggregate that would take additional parameter as a condition ? For example, say I have a table like this
id;value 1;45 2;13 3;0 4;90 I'd like to do something like this SELECT min_some_cond_aggregate(value,0) FROM table to get the minimal value from table greater than 0, in this case 13. I can't do SELECT min(value) FROM table WHERE value > 0 as this will mess my other computations. My current solution involves a function operating on the output of array_accum from the docs, but I'm looking for more elegant solution. Is this possible at all ? I'm running 8.1. regards mk
