最近发现现有框架的通用查询存储过程的性能慢，于是仔细研究了下代码：
发现每次查询都需要按条件查询依次Area表，性能太低，于是利用临时表将符合条件的记录取出来，然后针对临时表进行查询，代码修改如下：
Alter PROCEDURE [dbo].[AreaSelect]
@PageSize int=0,
@CurrentPage int=1,
@Identifier int=NULL,
@ParentId int=NULL,
@AreaLevel int=NULL,
@Children int=NULL,
@AreaName nvarchar(50)=NULL,
@Path nvarchar(MAX)=NULL,
@Status int=NULL,
@Alt int=NULL
AS
BEGIN
SET NOCOUNT ON;
IF (NOT @AreaName IS NULL) SET @AreaName='%'+@AreaName+'%'
IF (NOT @Path IS NULL) SET @Path='%'+@Path+'%'
IF (@PageSize>0)
BEGIN
--创建临时表
Select
Identifier,ParentId,AreaLevel,Children,AreaName,Path,Status,Alt
INTO #temp_Area
FROM Area Where
(@Identifier IS NULL or Identifier=@Identifier)AND
(@ParentId IS NULL or ParentId=@ParentId)AND
(@AreaLevel IS NULL or AreaLevel=@AreaLevel)AND
(@Children IS NULL or Children=@Children)AND
(@AreaName IS NULL or AreaName Like @AreaName)AND
(@Path IS NULL or Path Like @Path)AND
(@Status IS NULL or Status=@Status)AND
(@Alt IS NULL or Alt=@Alt)
order by AreaName asc
DECLARE @TotalPage int
DECLARE @SumCount int
--取总数
Select @SumCount=Count(Identifier) FROM #temp_Area
IF(@SumCount%@PageSize=0)
