These examples create the same 3-dimensional ARRAY type as Example: Three-Dimensional ARRAY Type, but use different syntax variations to define them.
The first example uses Teradata-style syntax to define a variant of the seismic_cube type, seismic_cube_2, based on the type measures_udt, which is defined in Example: Three-Dimensional ARRAY Type.
CREATE TYPE seismic_cube_2 AS measures_udt ARRAY [5][7][20];
The next example uses another variant of Teradata-style syntax to define an equivalent seismic_cube type named seismic_cube_3.
CREATE TYPE seismic_cube_3 AS measures_udt ARRAY [1:5][7][1:20];
