SQL更新，串數字

Question

在一個SQL Server數據庫中，我要更新一些字段，查詢（，是小數分隔符）：

UPDATE MyTbable 
SET 
Field1 = CAST('111,11' AS DEC(18,4)), 
Field2 = CAST('222,22' AS DEC(18,4)), 
Field3 = CAST('333,33' AS DEC(18,4)) 
WHERE Id = '1' 

我收到的錯誤： 錯誤的數據轉換鍵入varchar到數字。我試着跟投，同樣的問題

字段1，字段2和字段3是數字38,2

任何想法？

感謝，

Answer 1

使用.，而不是,

UPDATE MyTbable 
SET 
    Field1 = CAST('111.11' AS DEC(18,4)), 
    Field2 = CAST('222.22' AS DEC(18,4)), 
    Field3 = CAST('333.33' AS DEC(18,4)) 
WHERE Id = '1' 

如果你想以後選擇這些值作爲字符串，並將逗號，然後做到這一點：

select replace(cast(Field1 as varchar(30)), '.',','), 
     replace(cast(Field2 as varchar(30)), '.',','), 
     replace(cast(Field2 as varchar(30)), '.',','), 
where Id = '1' 

Answer 2

刪除逗號您查詢，如：

UPDATE MyTbable 
SET 
Field1 = CAST('11111' AS DEC(18,4)), 
Field2 = CAST('22222' AS DEC(18,4)), 
Field3 = CAST('33333' AS DEC(18,4)) 
WHERE Id = '1' 

，或者你可以rmove使用逗號替代：

replace('111,11',',','.') 

Answer 3

以逗號出來。

UPDATE MyTbable 
SET 
Field1 = CAST(REPLACE('111,11',',','.') AS DEC(18,4)), 
Field2 = CAST(REPLACE('222,22',',','.') AS DEC(18,4)), 
Field3 = CAST(REPLACE('333,33',',','.') AS DEC(18,4)) 
WHERE Id = '1'
