用SQL脚本移除视图中存在的机器名

用SQL脚本移除视图中存在的机器名

例子: msccdr.cdr.DimRMAReturnMethod

CREATE VIEW CDR.DimRMAReturnMethod ( ReturnMethodId,srcReturnMethodCode,ReturnMethodName,IsDeleted  ,TrackingID,ETLInsertDtTm ,ETLUpdateDtTm)

AS SELECT t.ReturnMethodId,t.srcReturnMethodCode,t.ReturnMethodName,t.IsDeleted,t.TrackingID,t.ETLInsertDtTm,t.ETLUpdateDtTm

FROM [MSCBISQLX01].[CDR].dbo.DimRMAReturnMethod t WITH (NOLOCK)

处理方法

*.查询出视图中存在机器名的视图信息

USE Database

GO

SELECT

b.name,

c.referenced_server_name,

c.referenced_database_name,

c.referenced_schema_name,

a.definition,

b.create_date,

b.modify_date

FROM sys.sql_modules AS a

JOIN

sys.objects AS b

ON a.object_id = b.object_id

JOIN

sys.sql_expression_dependencies AS c

ON b.object_id = c.referencing_id

WHERE b.type = 'V'

AND c.referenced_server_name IS NOT NULL

*.修改视图中存在机器名的视图

SET NOCOUNT ON;

DECLARE @definition VARCHAR(MAX)

DECLARE @ServerN VARCHAR(50)

DECLARE View_Cursor CURSOR SCROLL

FOR (

SELECT

c.referenced_server_name,

a.definition

FROM sys.sql_modules AS a

JOIN

sys.objects AS b

ON a.object_id = b.object_id

JOIN

sys.sql_expression_dependencies AS c

ON b.object_id = c.referencing_id

WHERE b.type = 'V'

AND c.referenced_server_name IS NOT NULL

)

OPEN View_Cursor;

FETCH NEXT FROM View_Cursor INTO @ServerN,@definition;

WHILE @@fetch_status = 0

BEGIN

SELECT @definition = REPLACE (@definition,'CREATE VIEW','ALTER VIEW')

SELECT @definition = REPLACE (@definition,'['+@ServerN+']'+'.','')

--print(@definition);

exec(@definition);

FETCH NEXT FROM View_Cursor INTO @ServerN,@definition;

END

CLOSE View_Cursor;

DEALLOCATE View_Cursor;

GO
