爲索引列表生成CREATE腳本

Question

作爲更改排序規則練習的一部分，我有一個索引列表（122），需要刪除並重新創建。我怎樣才能重新創建這些索引，而無需通過GUI並將其腳本編寫到查詢窗口中？從這個腳本

WITH indexCTE AS 
    ( 
    SELECT Table_Name, Column_Name, Collation_Name 
    FROM information_schema.columns 
    WHERE Collation_Name IS NOT NULL AND Collation_Name = 'Modern_Spanish_CI_AS' 
    ), 
    indexCTE2 AS 
    (
    SELECT i.Name [Index Name], OBJECT_NAME(i.object_ID) [Table Name], c.Name [Column Name] 
    FROM sys.indexes i 
    INNER JOIN sys.index_columns ic ON i.index_id = ic.index_id AND i.object_id = ic.object_id 
    INNER JOIN sys.columns c ON ic.column_id = c.column_id AND ic.object_id = c.OBJECT_ID 
    WHERE EXISTS (SELECT 1 FROM indexCTE t1 WHERE t1.Table_Name = OBJECT_NAME(i.object_ID) AND t1.Column_Name = c.Name) 
    ) SELECT * FROM indexCTE2 

正如你可能會說，我仍然獲得

我的索引列表中的小DBA所以請耐心等待我！

謝謝！

Answer 1

你很親密，我會說 - 我試過這個，你可以驗證這是否適用於你，並顯示你預期的122個索引被重新創建？

UPDATE：增加了確定CLUSTERED與NONCLUSTERED索引類型的功能，並將INCLUDEd列添加到索引定義中。

WITH indexCTE AS 
(
    SELECT DISTINCT 
     i.index_id, i.name, i.object_id 
    FROM 
     sys.indexes i 
    INNER JOIN 
     sys.index_columns ic 
      ON i.index_id = ic.index_id AND i.object_id = ic.object_id 
    WHERE 
     EXISTS (SELECT * FROM sys.columns c 
       WHERE c.collation_name = 'Modern_Spanish_CI_AS' 
       AND c.column_id = ic.column_id AND c.object_id = ic.object_id) 
), 
indexCTE2 AS 
(
    SELECT 
     indexCTE.name 'IndexName', 
     OBJECT_NAME(indexCTE.object_ID) 'TableName', 
     CASE indexCTE.index_id 
      WHEN 1 THEN 'CLUSTERED' 
      ELSE 'NONCLUSTERED' 
     END AS 'IndexType', 
     (SELECT DISTINCT c.name + ',' 
     FROM 
      sys.columns c 
     INNER JOIN 
      sys.index_columns ic 
       ON c.object_id = ic.object_id AND ic.column_id = c.column_id AND ic.Is_Included_Column = 0 
     WHERE 
      indexCTE.OBJECT_ID = ic.object_id 
      AND indexCTE.index_id = ic.index_id 
     FOR XML PATH('') 
     ) ixcols, 
     ISNULL(
     (SELECT DISTINCT c.name + ',' 
     FROM 
      sys.columns c 
     INNER JOIN 
      sys.index_columns ic 
       ON c.object_id = ic.object_id AND ic.column_id = c.column_id AND ic.Is_Included_Column = 1 
     WHERE 
      indexCTE.OBJECT_ID = ic.object_id 
      AND indexCTE.index_id = ic.index_id 
     FOR XML PATH('') 
     ), '') includedcols 
    FROM 
     indexCTE 
) 
SELECT 
    'CREATE ' + IndexType + ' INDEX ' + IndexName + ' ON ' + TableName + 
     '(' + SUBSTRING(ixcols, 1, LEN(ixcols)-1) + 
     CASE LEN(includedcols) 
      WHEN 0 THEN ')' 
      ELSE ') INCLUDE (' + SUBSTRING(includedcols, 1, LEN(includedcols)-1) + ')' 
     END 
FROM 
    indexCTE2 
ORDER BY 
    TableName, IndexName 

您是否在尋找CREATE INDEX聲明？

DROP TABLE＃temp1中

Answer 3

這是一個有點題外話，但想到我會反正這提示：

如果您不想繼續執行腳本在SQL Server Management Studio中，您可以創建一個runmyscripts.bat文件，包括像：

@echo off 

echo Execute Scripts... 

sqlcmd -i C:\Scripts\myscript1.sql 
sqlcmd -i C:\Scripts\myscript2.sql 

echo Scripts Complete. 
echo Press any button to exit. 
pause 

Answer 4

偉大的腳本馬克。 我認爲它唯一缺少的是每列上的升序或降序指標。我已經修改了您的腳本以包含索引列的case語句，以便在ASC或DESC中添加，具體取決於sys.index_columns視圖的is_descending_key列。

WITH indexCTE AS 
(
    SELECT DISTINCT 
     i.index_id, i.name, i.object_id 
    FROM 
     sys.indexes i 
    INNER JOIN 
     sys.index_columns ic 
      ON i.index_id = ic.index_id AND i.object_id = ic.object_id 
    WHERE 
     EXISTS (SELECT * FROM sys.columns c 
       WHERE 
       c.collation_name = 'Modern_Spanish_CI_AS' 
       AND c.column_id = ic.column_id AND c.object_id = ic.object_id) 
), 
indexCTE2 AS 
(
    SELECT 
     indexCTE.name 'IndexName', 
     OBJECT_NAME(indexCTE.object_ID) 'TableName', 
     CASE indexCTE.index_id 
      WHEN 1 THEN 'CLUSTERED' 
      ELSE 'NONCLUSTERED' 
     END AS 'IndexType', 
     (SELECT CASE WHEN ic.is_descending_key = 1 THEN c.name + ' DESC ,' 
       ELSE c.name + ' ASC ,' 
       END 
     FROM 
      sys.columns c 
     INNER JOIN 
      sys.index_columns ic 
       ON c.object_id = ic.object_id AND ic.column_id = c.column_id AND ic.Is_Included_Column = 0 
     WHERE 
      indexCTE.OBJECT_ID = ic.object_id 
      AND indexCTE.index_id = ic.index_id 
     FOR XML PATH('') 
     ) ixcols, 
     ISNULL(
     (SELECT DISTINCT c.name + ',' 
     FROM 
      sys.columns c 
     INNER JOIN 
      sys.index_columns ic 
       ON c.object_id = ic.object_id AND ic.column_id = c.column_id AND ic.Is_Included_Column = 1 
     WHERE 
      indexCTE.OBJECT_ID = ic.object_id 
      AND indexCTE.index_id = ic.index_id 
     FOR XML PATH('') 
     ), '') includedcols 
    FROM 
     indexCTE 
) 
SELECT 
    'CREATE ' + IndexType + ' INDEX ' + IndexName + ' ON ' + TableName + 
     '(' + SUBSTRING(ixcols, 1, LEN(ixcols)-1) + 
     CASE LEN(includedcols) 
      WHEN 0 THEN ')' 
      ELSE ') INCLUDE (' + SUBSTRING(includedcols, 1, LEN(includedcols)-1) + ')' 
     END

ORDER BY 
    TableName, IndexName 

Answer 5

在TechNet有一個相對完整的解決方案。

調整查詢到您的願望：

• SYS.TABLES在選擇
• 刪除sys.views
• 刪除默認值/加一些有條件的地方
