我的存儲過程執行多次？

Question

我寫了一個存儲過程來過濾我的表。它工作正常，並選擇正確的記錄，但在結果例如如果查詢必須返回一條記錄。

而不是一個記錄返回太多的記錄是否有可能我的存儲過程執行多次？

我用這個代碼：

ALTER PROCEDURE [dbo].[propertyFilterByCity] 
    @city NVARCHAR(150) = NULL, 
    @DefaultPageIndex smallint = NULL, 
    @DefaultPageSize smallint = NULL, 
    @RecordCount bit = NULL, 
    @MinPrice decimal(18, 0) = NULL, 
    @MaxPrice decimal(18, 0) = NULL, 
    @bedRoom smallint = NULL, 
    @PropertyType NVARCHAR(20) = NULL, 
    @requestType NVARCHAR(20) = NULL,

請幫我解決這個問題，謝謝！

首先，存儲過程不會運行多次。

原因可能是你從Estate表中加入了多個表。如果這些連接不是1到1，而是1到n，則會爲每個可能的連接獲取結果行。

例如，如果一個遺產有多個圖片，您會在結果中爲每個遺產圖片獲得一行。
