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);
The following query returns an element value, which is the minimum of all the element values in the shot1 array.
SELECT ARRAY_MIN(shot1) FROM seismic_data;
The following query returns an element value, which is the minimum of the element values within the specified scope of the shot1 array.
SELECT ARRAY_MIN(shot1, NEW arrayVec(5,5), NEW arrayVec(10,10)) FROM seismic_data;
The following is the same query using method-style syntax.
SELECT shot1.ARRAY_MIN(NEW arrayVec(5,5), NEW arrayVec(10,10)) FROM seismic_data;
