从MySQL中的连接视图表中删除行

Question

我在表格中有45K行（125k中）我需要删除。

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

返回

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

Answer 1

执行SHOW CREATE VIEW tablename以查看哪些表位于联接视图的select中。结果将是：

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

当您拥有名为name（table1）列的表名时，您可以执行删除操作：

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

Answer 2

试试这个

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