Sure, you can use array_upper() - array_lower(): Zeit: 0,205 ms test=*# select array_upper(array[1,2,3],1) - array_lower(array[1,2,3],1); ?column? ---------- 2 (1 Zeile) or: test=*# select array_upper(array[1,2,3],1) - array_lower(array[1,2,3],1) + 1; ?column? ---------- 3 (1 Zeile) Or, if your array starts with the first element, simple: test=*# select array_upper(array[1,2,3,NULL,5],1); array_upper ------------- 5 (1 Zeile) Andreas -- Really, I'm not out to destroy Microsoft.
