Hi Monty & folks,
some weeks ago I posted the following (snipped). Sorry for bothering you
again.

The problem was how to select a certain row of a set before the rows are
GROUPed together. { All rows have the same value in one column, but
different values in another. I want to get the row - and only one row
for each value in the first column - with the smallest value in the
second column. }
I was pointed to the HAVING clause, but can't get it to work. Neither
can I find a good explanation for it in the docs. Can you explain it to
me please?
What about SELECT DISTINCT? Does it work in the .19 release?
Matthias
