HiveQL ALTER TABLE：NullPointerException，INSERT INTO：MISSING 表

Question

我在使用INSERT INTO和ALTER TABLE命令时遇到问题。 我在笔记中发现了以下代码，这表明它可能在某些时候起作用。 但是，它现在不起作用。 谁能指出错误？

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';

以下两项也失败：

INSERT INTO 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 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.');

与： FAILED: ParseException line 1:12 missing TABLE at 'anyoung' near 'toytable_docs' in select clause

当我尝试ALTER TABLE命令时，以下两项均失败：

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';

有人有任何见解吗？ 我已经用 Google 搜索过/SO 等。

Answer 1

缺少关键字 TABLE，它应该在表名之前：

use anyoung;
INSERT INTO TABLE toytable_docs 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.');
