HI all,
below is the view i´ve tried to create on a table. The purpose was to do
some math on one of the columns (retning). The column is a double precision
number. The result is that the function is not recognized ("ERROR: function
to_number(double precision, unknown) does not exist"). I´m a bit uncertain
on how the syntax is, so perhaps someone could point me in the right
direction?
thanks in advance,
Christian
