如何使用SQL Server 2005基于SQL语句集创建视图？

如何解决如何使用SQL Server 2005基于SQL语句集创建视图？

| 我写了一些SQL语句，最后给出了一个表。我想将整个语句集创建为\“ View \”。我怎么得到的？ 声明如下：

------------ Creating TempTable(#MasterTable) ----------------------
CREATE TABLE #MasterTable
    (ItemID INT,ItemName VARCHAR(100),Specifications VARCHAR(100),D1 VARCHAR(50),D2 VARCHAR(50),D3 VARCHAR(50),D1_Code VARCHAR(50),D2_Code VARCHAR(50),D3_Code VARCHAR(50))

------------ Creating TempTable(#TempItems) ----------------------

CREATE TABLE #TempItems(ItemID INT,D3_Code VARCHAR(50))
------------ Creating & Inserting TempTable(@Dim) ----------------------

DECLARE @Dim TABLE (DCodes VARCHAR(100))
INSERT INTO @Dim SELECT  D1_Code FROM MAS_SizeType WHERE  D1_Code <> \'\'
INSERT INTO @Dim SELECT  D2_Code FROM MAS_SizeType WHERE  D2_Code <> \'\'
INSERT INTO @Dim SELECT  D3_Code FROM MAS_SizeType WHERE  D3_Code <> \'\'

------------ Inserting data into TempTable(#MasterTable) ----------------------

INSERT INTO #MasterTable
SELECT     STR_Item.ItemID,STR_Item.ItemName,STR_Item_Specifications.SpecificationName,STR_Item.D1,STR_Item.D2,STR_Item.D3,MAS_SizeType.D1_Code,MAS_SizeType.D2_Code,MAS_SizeType.D3_Code
FROM         STR_Item INNER JOIN
                      MAS_SizeType ON STR_Item.SizeTypeID = MAS_SizeType.SizeTypeID INNER JOIN
                      STR_Item_Specifications ON STR_Item.SpecificationID = STR_Item_Specifications.SpecificationID

-------------------- Inserting Data into #TempItems Table ----------------------------
INSERT INTO #TempItems
    SELECT 
          *
    FROM #MasterTable

------------------Cursor for All dimensions details into single row for each items ----------------------

DECLARE @DCode VARCHAR(MAX),@Cnt INT
SET @Cnt = 0

DECLARE ColAdd CURSOR FOR
    SELECT DISTINCT DCodes FROM @Dim
OPEN ColAdd
FETCH NEXT FROM ColAdd INTO @DCode
WHILE (@@FETCH_STATUS = 0)
BEGIN
    SET @Cnt = 1
        EXECUTE (\'ALTER TABLE #TempItems ADD \' + @DCode + \' VARCHAR(50)\')
        EXECUTE(\'UPDATE #TempItems SET [\' + @DCode + \'] = M.D1
                    FROM #MasterTable M 
                INNER JOIN #TempItems T ON T.ItemID = M.ItemID AND M.D1_Code = \'\'\' + @DCode + \'\'\'\')
        EXECUTE(\'UPDATE #TempItems SET [\' + @DCode + \'] = M.D2
                    FROM #MasterTable M 
                INNER JOIN #TempItems T ON T.ItemID = M.ItemID AND M.D2_Code = \'\'\' + @DCode + \'\'\'\')
        EXECUTE(\'UPDATE #TempItems SET [\' + @DCode + \'] = M.D3
                    FROM #MasterTable M 
                INNER JOIN #TempItems T ON T.ItemID = M.ItemID AND M.D3_Code = \'\'\' + @DCode + \'\'\'\')


        FETCH NEXT FROM ColAdd INTO @DCode
END
CLOSE ColAdd
DEALLOCATE ColAdd
IF (@Cnt = 1)
BEGIN

    SELECT  @DCode = STUFF(( SELECT  DISTINCT \'],[\' + ltrim(DCodes) 
                            FROM  @Dim 
                            ORDER BY \'],[\' + ltrim(DCodes)
                            FOR XML PATH(\'\')

                                        ),1,2,\'\') + \']\'

    EXECUTE (\'SELECT ItemID,ItemName,Specifications,\' + @DCode + \' FROM #TempItems ORDER BY ItemName\') 
END

DROP TABLE #TempItems
DROP TABLE #MasterTable

    

解决方法

        这是一个存储过程：不是视图。视图是单个SELECT（可能带有CTE和UNION） 如果您需要从中进行选择，建议您尝试使用多语句表值函数。但是，存在一些限制可能会阻止这种情况。 YMMV。性能也很棒
