Major Description
ARRAY_LENGTH generates a type mismatch if the array is DECIMAL type.
Sample code:
!outputformat vertical
DROP TABLE IF EXISTS mytable;
CREATE TABLE IF NOT EXISTS mytable
(id UNSIGNED_INT NOT NULL,
b.myarray1 INTEGER ARRAY[10],
c.myarray2 VARCHAR ARRAY[20],
d.myarray3 DECIMAL(4,2) ARRAY[30],
CONSTRAINT pk PRIMARY KEY (id));
UPSERT INTO mytable(id, myarray1, myarray2, myarray3)
VALUES(1,ARRAY[1],ARRAY['a','b'],ARRAY[1.11,2.22,3.33]);
select * from mytable;
SELECT ARRAY_LENGTH(myarray1) from mytable;
SELECT ARRAY_LENGTH(myarray2) from mytable;
SELECT ARRAY_LENGTH(myarray3) from mytable;
Produces the following output run under SQLline:
