我的查询:
IF OBJECT_ID ('vw_F_GWLVL_RAW', 'V') IS NOT NULL
DROP VIEW vw_F_GWLVL_RAW ;
GO
CREATE VIEW vw_F_GWLVL_RAW WITH SCHEMABINDING
AS
SELECT S.SiteName, CAST(D.[Date] as Date) as [Date], CONVERT(CHAR(5),T.[Time]) as [Time], CAST(F.SampleValue as NUMERIC(6,3)) as ValueAsRecorded,
Q.Code as DataQualityCode, Q.QualityDesc as DataQualityDesc
FROM dbo.F_GWLVL_RAW AS F INNER JOIN
dbo.D_Site AS S ON F.D_Site_Key = S.D_Site_Key INNER JOIN
dbo.D_Date AS D ON F.D_Date_Key = D.D_Date_Key INNER JOIN
dbo.D_Time AS T ON F.D_Time_Key = T.D_Time_Key INNER JOIN
dbo.F_ODP_QC_GWLVL AS Q ON Q.[Site] collate database_default = S.[SiteName] AND
(CONVERT(datetime,CAST(D.[Date] as VARCHAR(30))+' '+CAST(T.[Time] as VARCHAR(30)),121) BETWEEN Q.StartTime AND Q.EndTime)
GO
CREATE UNIQUE CLUSTERED INDEX IX_GWLVL_RAW1 ON vw_F_GWLVL_RAW(SiteName,[Date],[Time])
即使我的转换使用确定性121类型,也会给我这个错误:
'Cannot create index on view "dbo.vw_F_GWLVL_RAW". The view contains a convert that is imprecise or non-deterministic.'
答案 0 :(得分:0)
创建INDEXED VIEWS。
您需要在CONVERT子句中使用确定性样式。默认值是非确定性的
尝试,CONVERT(DECIMAL(10,2))或CONVERT(DATETIME,'20131202',103)
