sql-server - SQL if语句在where子句中用于搜索数据库

我正在创建一个存储过程以返回搜索结果，其中某些参数是可选的。

我在where子句中需要“ if语句”，但无法使其正常工作。 where子句应仅按非null参数过滤。

这是sp

ALTER PROCEDURE spVillaGet
-- Add the parameters for the stored procedure here
@accomodationFK int = null,
@regionFK int = null,
@arrivalDate datetime,
@numberOfNights int,
@sleeps int = null,
@priceFloor money = null,
@priceCeil money = null
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here
select tblVillas.*, tblWeeklyPrices.price from tblVillas
INNER JOIN tblWeeklyPrices on tblVillas.villaId = tblWeeklyPrices.villaFK
where
    If @accomodationFK <> null then
        accomodationTypeFK = @accomodationFK
     @regionFK <> null Then
        And regionFK = @regionFK
    IF @sleeps <> null Then
        And sleeps = @sleeps
    IF @priceFloor <> null Then
        And price >= @priceFloor And price <= @priceCeil


END

任何想法如何做到这一点？

最佳答案

select tblVillas.*, tblWeeklyPrices.price
from tblVillas
INNER JOIN tblWeeklyPrices on tblVillas.villaId = tblWeeklyPrices.villaFK
where (@accomodationFK IS null OR accomodationTypeFK = @accomodationFK)
  AND (@regionFK IS null or regionFK = @regionFK)
  AND (@sleeps IS null OR sleeps = @sleeps)
  AND (@priceFloor IS null OR (price BETWEEN @priceFloor And @priceCeil))
