在操作mysql数据库表时出现以下错误。

网上google搜索相关问题，发现一位外国牛人这么解释：

1. If  you're running an operation on a large number of rows within a table  that uses the InnoDB storage engine, you might see this error:

2.  

3. ERROR 1206 (HY000): The total number of locks exceeds the lock table size

4.  

5. MySQL is trying to tell you that it doesn't have enough room to  store all of the row locks that it would need to execute your query. The  only way to fix it for sure is to adjust innodb_buffer_pool_size and  restart MySQL. By default, this is set to only 8MB, which is too small  for anyone who is using InnoDB to do anything.

6.  

7. If you need a temporary workaround, reduce the amount of rows you're  manipulating in one query. For example, if you need to delete a million  rows from a table, try to delete the records in chunks of 50,000 or  100,000 rows. If you're inserting many rows, try to insert portions of  the data at a single time.

原来是InnoDB表执行大批量数据的更新，插入，删除操作时会出现这个问题，需要调整InnoDB全局的innodb_buffer_pool_size的值来解决这个问题，并且重启mysql服务。

查看当前数据库存储引擎，在创建时使用 ENGINE=InnoDB类型。

默认的innodb_buffer_pool_size=8M

修改 innodb_buffer_pool_size的值：

1. innodb_buffer_pool_size=64M

再一次重启mysql服务器，执行表操作，成功执行完毕。
