Re: Howto determin the number of elemnts of an array

Hi Seven,
it would be better for me if it returned the number of elements as an
integer even if the array is empty (in this case it returns with NULL). No
metter this is easily can be worked around, but it would have been more
confortable.

Thank you very much.

array_upper(arrayname,dimension) will return the number of elements in the
specified dimension of array arrayname.
