将 Varchar 转换为十进制

Question

Can I convert varchar as decimal? I already tried this, but I receive the following error:

"Function argument value, type, or count is invalid"

The column adjust2,tax,sss_ee,sss_er,phic are the columns I'm trying to convert to decimal type.

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

I believe this is data issue, you have existing data that cannot be cast to decimal.

use TRY_PARSE instead.

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