These examples all create a 3-dimensional ARRAY type named seismic_cube based on the UDT measures_udt, which has the following SQL create text.

     CREATE TYPE measures_udt AS (
       amplitude INTEGER,
       phase     INTEGER, 
       frequency INTEGER);

The first example uses Teradata-style syntax and initializes all of its elements to nulls.

     CREATE TYPE seismic_cube AS 
       measures_udt ARRAY [1:5][1:7][1:20] 
     DEFAULT NULL;

The next example also uses Teradata-style syntax, but does not initialize its elements to nulls.

     CREATE TYPE seismic_cube AS 
     measures_udt ARRAY [1:5][1:7][1:20];
