创建临时 table 后缺少 'end' 错误

Question

我正在创建一个存储过程，我应该在其中创建一个临时 table 来插入数据并在末尾显示（这是一项任务，所以我必须创建临时 table按照说明）。

我应该在这个存储过程中使用游标。我正在创建临时 table，然后我正在创建一个游标。但是我在创建 table.

后收到错误 missing 'end'

CREATE DEFINER=`root`@`localhost` PROCEDURE `walkerMasterSummary`()

我没有消除临时 table 或游标的选项。我该如何解决这个错误？

Answer 1

游标的声明应该在创建临时文件之前table

我也取消了临时插入代码的注释table
