Example: Querying a 2-D ARRAY Data Type and Table using ARRAY_COUNT_DISTINCT - Teradata Vantage - Analytics Database

Consider the following 2-D ARRAY data type and table.

CREATE TYPE shot_ary AS INTEGER ARRAY[1:50][1:50];
CREATE TABLE seismic_data (
   id INTEGER,
   shot1 shot_ary,
   shot2 shot_ary);

In the following query, ARRAY_COUNT_DISTINCT returns the number of elements whose value is equal to 100 within the specified scope of the shot1 array.

SELECT ARRAY_COUNT_DISTINCT(shot1, NEW arrayVec(5,5), NEW arrayVec(10,10), 100) FROM seismic_data;
