| 1. | Does mysql 5 . 0 have statement - level or row - level triggers 0是否有语句级和行级的触发器 |
| 2. | For server - level triggers , see 有关服务器级触发器,请参阅 |
| 3. | When set to 0 , server - level triggers cannot be fired recursively 当设置为0 ( off )时,服务器级触发器不能递归激发。 |
| 4. | When this option is set to 1 , server - level triggers will be allowed to fire recursively 当此选项设置为1 ( on )时,将允许服务器级触发器递归激发。 |
| 5. | Server trigger recursion option to specify whether to allow server - level triggers to fire recursively 选项可指定是否允许服务器级触发器递归激发。 |
| 6. | This impersonation depends on whether the module is a database - level module , such as a stored procedure or function , or a server - level module , such as a server - level trigger 此模拟取决于模块是数据库级模块(如存储过程或函数)还是服务器级模块(如服务器级触发器) 。 |
| 7. | Secondly , unless a table uses statement - level triggers , it is as expensive to check whether a row exists with an explicit query as it is to perform an update statement that does not find a row to update 其次,除非某一个表使用语句级触发器,否则,用显式查询来检查某一行是否存在的代价就与未找到要更新的行就执行update语句的代价一样高。 |
