PS: The reorganization fragmentation index of a single table is very simple.
The syntax is as follows: DBCC DBReindex(' A.dbo.C ')//A : database C : database table
The syntax for rebuilding indexes and fragments for all tables is as follows:
Use [数据库名称]
Go
DECLARE @DBCCString NVARCHAR(1000)
DECLARE @TableName VARCHAR(100)
DECLARE Cur_Index CURSOR
FOR
SELECT Name AS TblName
FROM sysobjects
WHERE xType='U'
ORDER BY TblName
FOR READ ONLY
OPEN Cur_Index
FETCH NEXT FROM Cur_Index
INTO @TableName
WHILE @@FETCH_STATUS=0
BEGIN
SET @DBCCString = 'DBCC DBREINDEX(@TblName,'''')WITH NO_INFOMSGS'
EXEC SP_EXECUTESQL @DBCCString,N'@TblName VARCHAR(100)', @TableName
PRINT '重建表' + @TableName +'的索引........OK!'
FETCH NEXT FROM Cur_Index INTO @TableName
END
CLOSE Cur_Index
DEALLOCATE Cur_Index
PRINT '操作完成！'
go
DBCC UPDATEUSAGE(0);
