将Varchar转换为十进制

Question

我可以将varchar转换为十进制吗？我已经尝试过了，但是收到以下错误：

  

“函数参数值，类型或计数无效”

adjust2,tax,sss_ee,sss_er,phic列是我要转换为十进制类型的列。

Dim strQuery As String = "SELECT DATER, CODE, ID, REG_HRS, R_OT, RD_OT, RD_8, HOL_OT," &
         " HOL_OT8, ND, ABS_TAR, ADJUST1, GROSS_PAY, CAST(ADJUST2 AS DECIMAL(10,2)), CAST(TAX AS DECIMAL(10,2))," &
         " CAST(SSS_EE AS DECIMAL(10,2)), CAST(SSS_ER AS DECIMAL(10,2)), CAST(PHIC AS DECIMAL(10,2)), NET_PAY, REG_PAY FROM [" & dbfFileName & "]"

Answer 1

我认为这是数据问题，您现有的数据无法转换为十进制。

改为使用TRY_PARSE。

, COALESCE(TRY_PARSE(ADJUST2 AS DECIMAL(10,2)), 0.00)
