如何为数据库中的每个视图创建调用sp_refreshview的存储过程？

Question

今天我跑了

select 'exec sp_refreshview N''['+table_schema+'].['+table_name+']'''
from information_schema.tables
where table_type = 'view'

这会产生很多:exec sp_refreshview N'[SCHEMA].[TABLE]'.然后我将结果复制到查询编辑器窗口并运行所有这些exec.

我如何一次完成这一切？我想有一个名为dev.RefreshAllViews的存储过程,我可以执行它来执行此操作...

DECLARE @RefreshScript varchar(max)
set @RefreshScript = ''


select @RefreshScript= @RefreshScript + 'exec sp_refreshview N''['+table_schema+'].['+table_name+']''
'
from information_schema.tables
where table_type = 'view'



exec (@RefreshScript)

如果您的视图中有[]字符存在任何危险,您可能需要查看QUOTENAME函数.

或者还有一个光标

DECLARE @viewName AS VARCHAR(255)

    DECLARE listOfViews CURSOR
        FOR SELECT  '[' + SCHEMA_NAME(uid) + '].[' + name + ']'
            FROM    sysobjects
            WHERE   xtype = 'V'


    OPEN listOfViews

    FETCH NEXT FROM listOfViews INTO @viewName

    WHILE ( @@FETCH_STATUS <> -1 )
        BEGIN


            FETCH NEXT FROM listOfViews INTO @viewName

            BEGIN TRY
                EXEC sp_refreshview @viewName
                PRINT @viewName + ' refreshed OK'
            END TRY
            BEGIN CATCH
                PRINT @viewName + ' refresh failed'
            END CATCH
        END

    CLOSE listOfViews

    DEALLOCATE listOfViews
