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_GET returns the element value located in position [5][10] of the shot1 array.

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

The following is the same query using method-style syntax.

SELECT shot1.ARRAY_GET(NEW arrayVec(5,10)) FROM seismic_data;
