使用 T-SQL 和 Microsoft SQL Server,当我在 2 个整数之间进行除法时,我想指定小数位数,例如:
Using T-SQL and Microsoft SQL Server I would like to specify the number of decimal digits when I do a division between 2 integer numbers like:
select 1/3
当前返回 0
.我希望它返回 0,33
.
That currently returns 0
. I would like it to return 0,33
.
类似于:
select round(1/3, -2)
但这行不通.我怎样才能达到预期的结果?
But that doesn't work. How can I achieve the desired result?
如果您正在寻找常量,stb 和 xiowl 的建议很好.如果您需要使用现有的整数字段或参数,您可以先将它们转换为浮点数:
The suggestions from stb and xiowl are fine if you're looking for a constant. If you need to use existing fields or parameters which are integers, you can cast them to be floats first:
SELECT CAST(1 AS float) / CAST(3 AS float)
或
SELECT CAST(MyIntField1 AS float) / CAST(MyIntField2 AS float)
