SQL更新，串数字

Question

在一个SQL Server数据库中，我要更新一些字段，查询（，是小数分隔符）：

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' 

我收到的错误： 错误的数据转换键入varchar到数字。我试着跟投，同样的问题

字段1，字段2和字段3是数字38,2

任何想法？

感谢，

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' 

如果你想以后选择这些值作为字符串，并将逗号，然后做到这一点：

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

Answer 2

删除逗号您查询，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使用逗号替代：

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

Answer 3

以逗号出来。

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'
