用友U8 | 【后台管理】消息任务太多了，影响客户端登录速度，清空后台消息任务？

问题描述：

很多同事反馈客户端登录很慢，很卡，查看后台消息记录，有20W条消息记录，这个很影响登录速度，所以后台要清理一下。

处理方法：

1、清理后台消息记录：

 使用的数据库是【UFSystem】 

select *from UA_Message   

select *into UA_Message_20210630 from UA_Message    ----备份消息审批记录

delete UA_Message  where  datediff(day,dSend,getdate()) >15  ----保留近15天的消息记录

2、优化一下数据库索引

DECLARE @SQL nvarchar(1000)
DECLARE @TableName nvarchar(100)

if EXISTS(Select 1 Where @@version Like 'Microsoft SQL Server  2000 %')
 DECLARE crTmp CURSOR OPTIMISTIC FOR
  SELECT [NAME] FROM sysobjects WHERE [xtype] = 'U' Order By [NAME]
ELSE
 DECLARE crTmp CURSOR OPTIMISTIC FOR
  SELECT [NAME] FROM sys.tables WHERE [type] = 'U' Order By [NAME]


OPEN crTmp
FETCH NEXT FROM crTmp INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
    Print '       '   
    Print '========================================================================='   
 Print '当前表：' + @TableName    

 SET @SQL = 'DBCC DBREINDEX([' + @TableName + '])'
 EXECUTE (@SQL)
    
    SET @SQL = 'UPDATE STATISTICS [' + @TableName + ']'
 EXECUTE (@SQL)

 Print '       '  
    Print @TableName + '   执行完毕'
    Print '========================================================================='   
 
 FETCH NEXT FROM crTmp INTO @TableName
END

CLOSE crTmp
DEALLOCATE crTmp

GO
