SQL Server存儲過程/光標

Question

我有一個包含20個空間表（Zoom1-Zoom20）的列表，並在這些表中彈出時間無效的幾何圖形。當無效的幾何體發生我運行下面的語句來找出其中的無效幾何形狀：

SELECT ID FROM Zoom10 WhERE Location.STIsValid() = 0 

通常我要運行的每一個縮放表格上面的語句（即導致無效幾何不表示錯誤，變焦表有無效的幾何形狀），當結果從SELECT語句返回我運行下面的語句來糾正幾何：

UPDATE MGeoZoom10 set Location = Location.MakeValid() where Location.STIsValid() = 0 

我的問題是可以在這個過程中有一個存儲過程，獲取的列表自動放大表

select name from sys.tables where name like '%zoom' 

，然後循環通過與

SELECT ID FROM Zoom10 WhERE Location.STIsValid() = 0 

變焦表，如果返回結果其上運行的變焦表更新語句？

Answer 1

試試這個：

sp_msforeachtable ' 
if ''?'' Like ''%Zoom%'' 
    Begin 
     If Exists(SELECT ID FROM ? WhERE Location.STIsValid() = 0) 
      UPDATE ? set Location = Location.MakeValid() where Location.STIsValid() = 0 
    End  
'

你有2層名爲的UDF和STIsValid MakeValid？如果是這樣，你可以做這樣的事情...

SELECT id INTO #Processed FROM Sysobjects WHERE name = '(no such table)' 

    DECLARE @TableId int, @TableName varchar(255), @CorrectionSQL varchar(255) 

    SELECT @TableId = MIN(id) FROM Sysobjects WHERE type = 'U' AND name LIKE '%zoom' 
    AND id NOT IN (SELECT id FROM #Processed) 

    SET @TableId = ISNULL(@TableId, -1) 

    WHILE @TableId > -1 BEGIN 

     PRINT @TableId 

     SELECT @TableName = name FROM Sysobjects WHERE type = 'U' AND id = @TableId 
     SET @CorrectionSQL = 'UPDATE ' + @TableName + ' SET Location = dbo.MakeValid(Location) where dbo.STIsValid(Location) = 0' 

     PRINT @CorrectionSQL 
     EXEC(@CorrectionSQL) 


     INSERT INTO #Processed (id) VALUES(@TableId) 

     SELECT @TableId = MIN(id) FROM Sysobjects WHERE type = 'U' AND name IN ('DimAccount', 'DimCurrency', 'DimCustomer') 
      AND id NOT IN (SELECT id FROM #Processed) 

    END
