如何重建sql数据库索引

 自己做个记号：
压缩数据库：
--清空日志
DUMP  TRANSACTION  库名  WITH  NO_LOG   

--截断事务日志：
BACKUP LOG 库名 WITH NO_LOG

--收缩数据库
DBCC SHRINKDATABASE(库名)

--收缩指定数据文件,1是文件号,可以通过这个语句查询到:select * from sysfiles
DBCC SHRINKFILE(1)

重建数据库索引：

USE DatabaseName --Enter the name of the database you want to reindex

DECLARE @TableName varchar(255)
DECLARE TableCursor CURSOR FOR

SELECT Table_Schema+'.'+Table_Name FROM information_schema.tables WHERE table_type = 'base table'

OPEN TableCursor

FETCH NEXT FROM TableCursor INTO @TableName

WHILE @@FETCH_STATUS = 0
BEGIN

DBCC DBREINDEX(@TableName,' ',90)

FETCH NEXT FROM TableCursor INTO @TableName
END

CLOSE TableCursor
DEALLOCATE TableCursor
