我编写了一个过滤表格的存储过程。它工作正常，并选择正确的记录，但在结果中，例如，如果查询必须返回一条记录。
而不是一条记录返回太多记录，我的存储过程可能会执行多次？
我使用此代码：
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,
@Parking bit = NULL,
@RemoteParking bit = NULL,
@Lobby bit = NULL,
@AssemblyHall bit = NULL,
@Gym bit = NULL,
@Surveillance bit = NULL,
@FireAlarm bit = NULL,
@FireFighting bit = NULL,
@Pool bit = NULL,
@Sauna bit = NULL,
@Jacuzzi bit = NULL,
@Carwash bit = NULL,
@Laundry bit = NULL,
@Custodian bit = NULL,
@Shooting bit = NULL,
@TheftAlarm bit = NULL,
@PanelFit bit = NULL,
@Sentry bit = NULL,
@CentralSatellite bit = NULL,
@CentralAntenna bit = NULL,
@Fireplaces bit = NULL,
@MasterRoom bit = NULL,
@Patio bit = NULL,
@Barbecue bit = NULL,
@UPS bit = NULL,
@RoofGarden bit = NULL

请帮我解决这个问题谢谢！

首先，存储过程不会多次运行。
原因可能是您从Estate表中加入多个表。如果这些连接不是1到1，而是1到n，那么每个可能的连接都会得到一个结果行。
例如，如果一个地产有多个图像，你的结果中的每个地产图像都会有一行。
