I am trying to create a updateable partitioned view on Enterprise Edition and partition col is res_date. (there are 4 partition tables Q1 - Q4 and a view that does a union all. If I set the contraint on ES_DATE using this syntax CHECK (month(ES_DATE) >= 10 and month(ES_DATE) <= 12), i am able to insert the correct value into the table (table insert) but I am not able to insert into the view - unable to use a function in distributed view constarint defintion. I am able to insert into view if I hard code dates in the constarint definition. CHECK (ES_DATE >= '1/1/05' and ES_DATE <= '3/31/05') How do I get this working without hard coding dates? CREATE TABLE [dbo].[PT_Q1_AV] ( [OWNER] [varchar] (6) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [ES_DATE] [datetime] NOT NULL , [TYPE] [varchar] (6) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [NUM] [int] NULL , [CT] [char] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [ML] [smallint] NULL ) ON [PRIMARY] GO ALTER TABLE [dbo].[PT_Q1_AV] ADD CONSTRAINT [PK_PT_Q1_AV] PRIMARY KEY CLUSTERED ( [OWNER], [ES_DATE], [TYPE] ) ON [PRIMARY] , CHECK (month(ES_DATE) >= 10 and month(ES_DATE) <= 12) GO this syntax CHECK (month(ES_DATE) >= 1 and month(ES_DATE) <= 3) does not let me insert into view. this syntax CHECK (ES_DATE >= '1/1/05' and ES_DATE <= '3/31/05') does allow me to insert into view
