I am doing this
declare @num float = 7708369000
select @num as [float],
convert(varchar, @num) as [varchar]
it gives me this
float varchar
---------------------- ------------------------------
7708369000 7.70837e+009
But I want this
float varchar
---------------------- ------------------------------
7708369000 7708369000
Please help.
Try using the Str function rather than using convert
DECLARE @num float = 7708369000;
SELECT Str(@num);
Try one of the following variations (values represent Max Value of BigInt and other Max type values) that meet your needs below. http://sqlfiddle.com/#!6/745c8f/1
