Question

最近，我试图在我的数据库的一个表中添加一个列，该表有316个表但是在以下命令之后：

mysql> ALTER TABLE view_Server ADD rsh_protocol VARCHAR(60);

我收到以下错误：

ERROR 1347 (HY000): 'itop.view_Server' is not BASE TABLE

我的所有搜索都没有成功，例如使用'``'。所以问题是这个错误的原因是什么？我该怎么办呢？

从“桌面”名称，您是否尝试向视图添加列？

贯穿以下各项：

CREATE TABLE x (id INT, name VARCHAR(255));

INSERT INTO x VALUES (1, 'One');
INSERT INTO x VALUES (2, 'Two');

-- A view with no change of column names
CREATE VIEW y AS SELECT id FROM x;

SELECT * FROM y;

-- Change the view, again using the base table column names
ALTER VIEW y AS SELECT name FROM x;

SELECT * FROM y;

-- Change the view, switching column name from `name` to `theName`
ALTER VIEW y (theName) AS SELECT name FROM x;

SELECT * FROM y;

-- Change the view, switching column name to `anotherName` by aliasing in the SELECT
ALTER VIEW y AS SELECT name anotherName FROM x;

SELECT * FROM y;

alter table error ERROR 1347（HY000）：'table-name'不是mysql中的BASE TABLE
