mysql - 从 MySQL 中的连接视图表中删除行

Question

我需要删除表中有 45K 行（共 125k）。

 DELETE FROM `tablename` WHERE `name` IS NULL ;

回来

ERROR 1395 (HY000): Can not delete from join view

Answer 1

做一个SHOW CREATE VIEW tablename看看哪些表在select连接视图中。结果将类似于：

CREATE VIEW tablename AS SELECT name, f2, f3 … FROM table1;

当您拥有具有名为name( table1) 的列的表的名称时，您可以进行删除：

DELETE FROM `table1` WHERE `name` IS NULL ;

Answer 2

尝试这个

DELETE FROM `tablename` WHERE `name`="" ;
