I wrote a function that returns a rowtype. The rowtype is assigned a
value by a query using SELECT INTO. The query sometimes will return
no rows. When it does, the function's return value is a row with no
values.
I would have expected it to return 0 rows, like the query itself. Am
I doing something wrong or is this the expected behavior? Is there a
standard way to code around this? I expected my client code to check
the number of rows returned to decide what to do next.
thanks
