HiveQL ALTER TABLE: NullPointerException, INSERT INTO: MISSING table - sql

Question

I'm having trouble with the INSERT INTO and ALTER TABLE commands. I found the following code in my notes, which indicates it probably worked at some point. However, it isn't working now. Can anyone point out mistakes?
DROP TABLE anyoung.toytable_docs;
CREATE TABLE IF NOT EXISTS anyoung.toytable_docs
(
id INT COMMENT 'unique document ID',
rev INT,
content STRING
)
COMMENT 'Employee details';
Both of the following also fail:
INSERT INTO TABLE anyoung.toytable_docs (`id`, `rev`, `content`) VALUES
('1', '1', 'The earth is flat'),
('2', '1', 'One hundred angels can dance on the head of a pin'),
('1', '2', 'The earth is flat and rests on a bull\'s horn'),
('1', '3', 'The earth is like a ball.');
use anyoung;
INSERT INTO TABLE toytable_docs (`id`, `rev`, `content`) VALUES
('1', '1', 'The earth is flat'),
('2', '1', 'One hundred angels can dance on the head of a pin'),
('1', '2', 'The earth is flat and rests on a bull\'s horn'),
('1', '3', 'The earth is like a ball.');
with: FAILED: ParseException line 1:32 cannot recognize input near 'VALUES' '(' ''1'' in select clause
When I attempt an ALTER TABLE command, both of the following failed:
ALTER TABLE anyoung.toytable_docs CHANGE content content STRING COMMENT 'The actual contents of the document';
use anyoung;
ALTER TABLE toytable_docs CHANGE content content STRING COMMENT 'The actual contents of the document';
Anyone have any insights? I already Googled/SO, etc.

Answer 1

The alternative is to insert from select:
with your_data as(
select stack(4,
'1', '1', 'The earth is flat',
'2', '1', 'One hundred angels can dance on the head of a pin',
'1', '2', 'The earth is flat and rests on a bull\'s horn',
'1', '3', 'The earth is like a ball.'
) as (id, rev, content)
)
use anyoung;
INSERT INTO TABLE toytable_docs
select id, rev, content from your_data;
