SQL Server 2008，将浮点数转换为字符串

Question

I need to convert float field (sp.[Current]) to string. The part of the query is:

SELECT 
    cast(sp.CustID as varchar(10)) CustID,
    cast(sp.Year as varchar(4)) Year,
    convert(nvarchar(50), sp.[Current])  AS Potential,
    sp.[Current] as Potential1

But after converting I get this result

I get exponential notation of the number. How can I improve it?

Answer 1

你可以像下面这样尝试

CONVERT(numeric(16,0), CAST([Current] AS FLOAT))

Answer 2

Try this

DECLARE @val float = 2000000.890

select convert(nvarchar(50),CAST(@val AS numeric(16,4)))

Answer 3

You can refer to this link How to use STR SQL SERVER as illustrated below

SELECT STR(float,25, 2)

Good Luck .
