您好，我在下面有以下代码......
DELIMITER $$

对于某个报告，因为我在程序运行期间无法添加进度条（它会导致应用程序无响应）我添加了一个名为＆＃34; ins＆＃34;只是为了查询每个查询的整个过程，然后在它之间添加一个ui操作，请参阅下面的代码：
Public Sub processRevRank(ByVal MyDate1 As String, ByVal MyDate2 As String)

MyDate2 = MyDate1
xDays = DateDiff("d", MyDate2, MyDate2)
ElseIf MyDate1 <> "" And MyDate2 = "" Then
MyDate1 = MyDate2
xDays = DateDiff("d", MyDate1, MyDate1)
ElseIf MyDate1 <> "" And MyDate2 <> "" Then

End If

我仍然不满意，因为没有响应仍然发生，我正在考虑在查询中删除UPDATE部分，因为ui在事务和日期中挂起了该部分。
我的问题是...... 如何在其上创建带有SELECT table1的存储过程，然后使用所选记录UPDATE table2并将其循环直到满足某个条件？任何循环选择和更新的简单sql存储过程？
谢谢！
答案 0 :(得分：0)
不是试图在UI中修复此问题（或作为第一步），您是否满意自己已经调整数据库以尽可能高效地运行这些查询？
