從SELECT中檢查數據，然後插入新值

Question

因此，我有一些包含數據的表，我需要根據舊數據獲取具有新數據的新表，然後將它們插入臨時表以供下一次處理。

但我有一些問題，我的SQL

DECLARE @PGNPGE float, 
      @PGHTTP400PCT float, 
      @PGHTTP500PCT float, 
      @PGSLPCT float, 
      @PGTME float; 

    DECLARE @tempTable TABLE (
     PViews int, 
     Http400 int, 
     Http500 int, 
     PTime int, 
     ExclSimul int, 
     DispSimul int, 
     SlowPages int, 
     AESWA int 
    ); 

    IF EXISTS (SELECT COUNT(*) FROM [ApplicationThreshold] WHERE [ApplicationID] = @AppID) 
    BEGIN 
     SELECT @PGNPGE = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 6; 
     SELECT @PGHTTP400PCT = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 31; 
     SELECT @PGHTTP500PCT = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 12; 
     SELECT @PGSLPCT = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 49; 
     SELECT @PGTME = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 72; 
    END 
    ELSE 
    BEGIN 
     SELECT @PGNPGE = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 6; 
     SELECT @PGHTTP400PCT = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 31; 
     SELECT @PGHTTP500PCT = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 12; 
     SELECT @PGSLPCT = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 49; 
     SELECT @PGTME = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 72; 
    END 

    INSERT INTO @tempTable (
     PViews, 
     Http400, 
     Http500, 
     PTime, 
     ExclSimul, 
     DispSimul, 
     SlowPages, 
     AESWA) 
    SELECT 
     [PViews] = CASE WHEN sel.[PGNPGE] < @PGNPGE THEN 1 ELSE 0 END, 
     [Http400] = CASE WHEN sel.[PGHTTP400PCT] > @PGHTTP400PCT THEN 1 ELSE 0 END, 
     [Http500] = CASE WHEN sel.[PGHTTP500PCT] > @PGHTTP500PCT THEN 1 ELSE 0 END, 
     [PTime] = CASE WHEN sel.[PGTME] > @PGTME THEN 1 ELSE 0 END, 
     [ExclSimul] = CASE WHEN ([PViews] + [Http400] + [Http500] + [PTime]) >= 1 THEN 1 ELSE 0 END, 
     [DispSimul] = CASE WHEN ([PViews] + [Http400] + [Http500] + [PTime]) > 1 THEN ([PViews] + [Http400] + [Http500] + [PTime]) ELSE 0 END, 
     [SlowPages] = CASE WHEN sel.[PGSLPCT] > @PGSLPCT THEN 1 ELSE 0 END, 
     [AESWA] = CASE WHEN [ExclSimul] >=1 THEN 0 ELSE [SlowPages] END 
    FROM (SELECT [PGNPGE], [PGHTTP400PCT], [PGHTTP500PCT], [PGSLPCT], [PGTME] 
      FROM [dbo].[TimeValue] 
      WHERE [ApplicationID] = @AppID 
      AND [Time] BETWEEN @DateFrom AND @DateTo) sel; 

SELECT * FROM @tempTable; 

和錯誤在那裏我添加新值

嘗試使用CTE在表變量中插入數據：

declare @PGNPGE float, 
    @PGHTTP400PCT float, 
    @PGHTTP500PCT float, 
    @PGSLPCT float, 
    @PGTME float; 

declare @tempTable TABLE 
(
    PViews int, 
    Http400 int, 
    Http500 int, 
    PTime int, 
    ExclSimul int, 
    DispSimul int, 
    SlowPages int, 
    AESWA int 
); 

IF EXISTS (SELECT COUNT(*) FROM [ApplicationThreshold] WHERE [ApplicationID] = @AppID) 
BEGIN 
    SELECT @PGNPGE = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 6; 
    SELECT @PGHTTP400PCT = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 31; 
    SELECT @PGHTTP500PCT = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 12; 
    SELECT @PGSLPCT = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 49; 
    SELECT @PGTME = Value FROM [ApplicationThreshold] WHERE [ThresholdID] = 72; 
END 
ELSE 
BEGIN 
    SELECT @PGNPGE = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 6; 
    SELECT @PGHTTP400PCT = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 31; 
    SELECT @PGHTTP500PCT = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 12; 
    SELECT @PGSLPCT = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 49; 
    SELECT @PGTME = Value FROM [ApplicationTypeThreshold] WHERE [ThresholdID] = 72; 
END 

;with ThresholdCTE 
as 
(
    SELECT 
     case when sel.[PGNPGE] < @PGNPGE then 1 else 0 end as [PViews],

    from [dbo].[TimeValue] 
    where [ApplicationID] = @AppID 
      and [Time] between @DateFrom and @DateTo 
) 

insert into @tempTable
