将 Varchar 转换为货币

Question

我正在尝试将一varchar列转换为货币，但我不断收到此错误

不允许从数据类型 varchar 隐式转换为 money。使用 CONVERT 函数运行此查询。

我没有像错误提示的那样使用转换函数吗？

Select
    tellerID,
    SUM(CASE 
           WHEN CONVERT(money, value1) IS NULL THEN '0' 
           ELSE CONVERT(money, value1) 
        END) AS [Total Value 1]

像这样尝试：

Select
tellerID,
SUM(CASE WHEN IsNumeric(value1) = 0 THEN 0 
       ELSE CAST(value1 AS decimal(18, 2)) 
END) as [Total Value 1]
