Converting float to decimal in SQL Server 2008

Question

I have a view which needs to return type decimal for columns stored as float.

I can cast each column to decimal as follows:

, CAST(Field1 as decimal) Fi         


        

Answer 1

12, 12 means no digits before the decimal separator: 12 digits in total, 12 of them being after the period.

Use a more appropriate range, say:

DECLARE @var FLOAT = 100
SELECT  CAST(@var as decimal(20,12))

which gives you 8 digits before the separator, or adjust it as needed.
