Hi all,
in a trigger I have a select statement like
select Key, Field from Tbl where ...
order by Field desc
I want to store the value of "Key" in a variable of
the trigger. But only for the first record.
I need to get the Key-Value of the record with Max(Field)
but unfortuantely Field is not unique and I cannot write
Select Key, Max(Field) from....
I remember that there was an answer sometimes ago
that suggested to somehow use rdb$database in the select
statement to only get one single record.
Can anybody help ?
TIA,
Markus
