OCOUNT takes an array expression as an argument and returns the number of elements that contain a value that is non-NULL or NULL. Elements that are in an uninitialized state are not counted. If the array is empty (all elements of the array are in an uninitialized state), then OCOUNT returns a value of 0.

If array_expr is NULL, an error is returned.

The OCOUNT method is compatible with the Oracle COUNT method for one-dimensional ARRAY types. However, the empty set of parentheses required by Teradata syntax is a deviation from Oracle syntax.
