如何自动执行sql查询。 [英] How to automatically execute sql queries.
问题描述
Hello All，
我有一个Table1，基于它我创建了Table2，其中包含所有公式和复杂性。这里我需要在将一些数据输入Table1时执行这些查询。
怎么可能？
基本上，我已经给出了一个文件（excel文件）上传选项在ASP.NET中，将excel文件数据存储到数据库中。现在，我需要在Table1上执行某些查询，以获取要存储在Table2中的操纵数据。每当用户在Table1中上传新数据时就会发生这种情况，因此Table2将定期更新。
它是否可以在C＃中使用存储过程。
喜欢，在Button Click事件中给出一个SQL命令
或
在SQL服务器中自行执行它。
我希望能很好地解释我的问题。
我将非常感谢可溶性答案。
谢谢

我尝试过：
我的查询示例需要自动执行：
INSERT INTO Table2
SELECT field1]，
count（当[field2] ='No Value'然后1结束时的情况）作为Results_1，
sum（当[field3]为空时的情况，然后是0，否则1结束）作为Result_2，
count（当[field4] ='是'然后1结束时的情况）作为Result_3，
sum（[field5] ='0'然后0其他1结束时的情况）as as Result_4，
FROM Table1
Hello All,
I have a Table1 and based upon it i created Table2 with all the formulas and complexity. Here i need to execute those queries whenever some data is entered into the Table1.
How it is possible?
Basically, i have given a file(excel file) upload option in the ASP.NET which stores the excel file data into the database. Now i need to execute certain queries on the Table1 for fetching manipulated data to be stored in Table2. And this has to occur whenever a user uploads a new data in Table1, hence Table2 will be regularly updated.
Will it work using a stored procedure in C#.
Like, giving a SQL commands in Button Click Event
Or
Executing it in SQL server it self.
I hope am clear in explaining my problem.
Soluble answers will be greatly appreciated.
Thanks

What I have tried:
Example of my query which needs to be automatically executed:
INSERT INTO Table2
SELECT field1],
count(case when [field2] = 'No Value' then 1 end) as Results_1,
sum(case when [field3] IS NULL then 0 else 1 end) as Result_2,
count(case when [field4] = 'Yes' then 1 end) as Result_3,
sum (case when [field5] = '0' then 0 else 1 end) as Result_4,
FROM Table1
推荐答案
您正在寻找的是触发器。它们基于插入/更新/删除自动执行。它们易于实施。看看下面的文章。
