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;
