Gridview中的舍入十进制

Question

我正在尝试将代码的结果舍入到2位小数，但ROUND不起作用。有帮助吗？谢谢！

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
     ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
     SelectCommand="SELECT [Id], [attempts], [total], (round(attempts / total,(2))) AS [Percentage] FROM [Game]">
</asp:SqlDataSource>

Answer 1

我打赌你可以使用

CAST(ROUND(attempts/total,2) as DECIMAL(12,2))

OR

attempts/CAST(total as DECIMAL(12,2))

OR

CAST(attempts AS DECIMAL(12,2))/total

Answer 2

试试这个       “              SelectCommand =“SELECT [Id]，[attempts]，[total]，round（（attempts / total），2）AS [Percentage] FROM [Game]”＆gt;         

更新：

你试过了吗？

SELECT Cast( 2.555 as decimal(53,2))

这将返回2.55。这就是你想要的吗？
