找出所有非xml索引

找出所有非xml索引

代码如下:
DECLARE cur CURSOR FOR
SELECT
[object_name]=s.name+'.'+OBJECT_NAME(A.object_id),
B.name
FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks'),NULL,null,null,null) AS A
JOIN sys.indexes AS B
ON A.[object_id]=B.[object_id]
AND A.[index_id]=B.[index_id]
JOIN sys.objects AS o
ON A.[object_id]=o.[object_id]
JOIN sys.schemas AS s
ON o.[schema_id]=s.[schema_id]
WHERE A.[index_id]>0
AND NOT EXISTS(
SELECT *
FROM sys.xml_indexes
WHERE A.[object_id]=[object_id]
AND A.[index_id]=[index_id]
);
OPEN cur;
DECLARE @objname varchar(128),@indname varchar(128);
DECLARE @sql nvarchar(4000);
FETCH NEXT FROM cur INTO @objname,@indname;
--重整所有索引,在这里先不管索引的碎片程度
WHILE @@FETCH_STATUS=0
BEGIN
SET @sql='ALTER INDEX '+@indname+' ON '+@objname+' REBUILD';
EXEC(@sql);
FETCH NEXT FROM cur INTO @objname,@indname;
END
CLOSE cur;
DEALLOCATE cur;
