C＃和SQL Server - 操作或服務器完成之前已超時的時間

Question

問題涉及到SQL Server和C＃。

我想在一個查詢中執行多個刪除語句。該格式具有以下結構：

DELETE from dbo.table where column = 'value' 

重複超過10萬次

我通過StringBuilder構建命令，並調用它的方式在我的C＃代碼：但是它需要

cmd.Connection = con; 
int rows = cmd.ExecuteNonQuery(); 

很多時間執行並以此錯誤結束：

The timeout period elapsed prior to completion of the operation or the server. Executing through Management Studio takes also a lot of time, and let me think that the query isn't performant enough. However, in this case the query is executed successfully.

顯然，使用較少的DELETE語句，由於查詢非常簡單，查詢正常結束。執行多個語句並避免此錯誤的最佳方法是什麼？

Answer 1

你不能只在你的查詢中用「IN」代替「=」執行一次DELETE執行嗎？ 這樣做：

DELETE from dbo.table where column in ('Param1','Param2','(...)')
