我有一個場景,我需要選擇一行並將值連接到單個變量中。問題是如果某個列是空的,那麼該部分必須被排除。但在我的情況下,它給了一個連字符,我用空的空間可以有人幫助我。如何檢查sql中的select語句中的每個值
我想這.....
SELECT @Location_Details = CONVERT(VARCHAR, ISNULL(O.CSS_No, ''))
+ '-' + CONVERT(VARCHAR, ISNULL(STREET.STREET_START_X, ''))
+ '-' + CONVERT(VARCHAR, ISNULL(STREET.STREET_START_Y, ''))
+ '-' + CONVERT(VARCHAR, ISNULL(STREETDES.STREET_DESCRIPTOR,
'')) + '-'
+ CONVERT(VARCHAR, ISNULL(STREETDES.LOCALITY_NAME, '')) + '-'
+ CONVERT(VARCHAR, ISNULL(STREETDES.TOWN_NAME, '')) + '-'
+ CONVERT(VARCHAR, ISNULL(HW.Description, '')) + '-'
+ CONVERT(VARCHAR, ISNULL(Add_stree.Additional_Street_Location_Text,
''))
FROM dbo.[order] O WITH (NOLOCK)
LEFT JOIN dbo.Order_USRN_Header USRN WITH (NOLOCK) ON USRN.Order_No = O.Order_No
LEFT JOIN DatabaseName.dbo.STREET STREET WITH (NOLOCK) ON STREET.USRN_NO = USRN.USRN_No
LEFT JOIN DatabaseName.dbo.STREET_DESCRIPTOR STREETDES WITH (NOLOCK) ON STREETDES.USRN_NO = USRN.USRN_No
LEFT JOIN dbo.High_Way_Authority HW WITH (NOLOCK) ON HW.HW_Authority_ID = STREET.SWA_ORG_REF
LEFT JOIN [DatabaseName].dbo.additional_STREET Add_stree WITH (NOLOCK) ON USRN.USRN_No = Add_stree.USRN
WHERE O.Order_No ='123456'
這給喜歡的結果....
