OLIMIT takes an array expression as an argument and returns the highest possible subscript value in the ARRAY type. If array_expr is a one-dimensional ARRAY type, OLIMIT returns an unsigned INTEGER value. If array_expr is a multidimensional ARRAY type, OLIMIT returns a new instance of the predefined ARRAY type ArrayVec, containing the subscript information.
If array_expr is NULL, an error is returned.
The OLIMIT method is compatible with the Oracle LIMIT method for one-dimensional ARRAY types. However, the empty set of parentheses required by Teradata syntax is a deviation from Oracle syntax.
