【问题描述】：

我需要有关我目前正在处理的存储过程的帮助。基本上存储过程可以正常工作并获取我所需的数据。我想保留这个功能并在存储过程中添加新的临时表，并用我得到的数据填充这个临时表。

我不知道在我的特定存储过程中应该在哪里/以及如何使用 INSERT INTO SELECT 语句或 SELECT INTO。下面我提交我的简化存储过程：

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[sp_GetHourReportData]

@dateFrom   SMALLDATETIME,
@dateTo     SMALLDATETIME,
@hourFrom   INT,
@hourTo     INT

AS
BEGIN

SET NOCOUNT ON;

CREATE TABLE tempTable
(
    -- fields
)

IF (DATEDIFF(DAY, @dateFrom, @dateTo) = 0)
    BEGIN
        SELECT -- fields
        FROM -- tables 
        WHERE -- conditions
    END
ELSE IF (DATEDIFF(DAY, @dateFrom, @dateTo) = 1)
    BEGIN
        SELECT -- fields
        FROM -- tables 
        WHERE -- conditions
    UNION ALL
        SELECT -- fields
        FROM -- tables
        WHERE -- conditions
    END
ELSE
    BEGIN
        SELECT -- fields
        FROM -- tables
        WHERE -- conditions    
    UNION ALL
        SELECT -- fields
        FROM -- tables 
        WHERE -- conditions
    UNION ALL
        SELECT -- fields
        FROM -- tables
        WHERE -- conditions
    END
END

谢谢。任何帮助将不胜感激。
