Mysql 错误代码：1137无法重新打开表：“amountforagents”

请在下面查看我的SP

  DELIMITER $$

在这里，我命令totalamountreceived根据sp中三列的总数分配排名，这三列在temp表中。但它显示错误代码：1137无法重新打开表：“amountforagents”

问题可能是UPDATE语句中的子选择位于底部

正如你所看到的：

同一时间内不能多次引用临时表 查询例如，以下操作不起作用：

mysql> SELECT * FROM temp_table, temp_table AS t2; 
ERROR 1137: Can't reopen table: 'temp_table' 

如果您引用了 在不同的存储函数中多次使用临时表 别名，即使引用出现在 功能

不管怎样，您的UPDATE语句似乎并没有完成很多工作。您在创建表之后立即对其使用更新，因此表将为空，因此不会有任何方式。也许您只是想在此处设置@TotalAmonReceived的变量

尝试删除此行：

update amountforagents 

然后修改SET语句，为@TotalAmonReceived创建变量和值：

这应该会给你你想要的结果，除非我误解了你想要达到的目标

总而言之：

不，我已经用SET@totalamunreceived I尝试过了，显示为空。您可以编辑您的原始帖子，显示您在使用SET@totalamunreceived时尝试过的代码吗？我上面发布的示例应该可以正常工作。与上面相同，我删除了更新amountforagents SET totalamountreceived=select ifnulldaymount、0+ifnullMonthAmount、0+ifnullYearAmount、0 from amountforagents，其中agentId=v_agentId；并添加集合@TotalAmonReceived=ifnull@DayAmount, 0 + ifnull@MonthAmount, 0 + ifnull@YearAmount, 0;@stpdevi我添加了您应该运行的整个代码块，作为我答案的一部分。我想你可能编辑错了，因为当我在本地运行它时，示例是有效的。嗨，alex，我在这里得到了总数，但需要显示基于代理总数的排名如何做到这一点？
