I have a database created in Microsoft SQL 2000 Enterprise Manager. I need to change the datatype for a column name EngrMultiplier in the table ProjectReCapParameter. The current datatype is INT and I would like to replace it to FLOAT. What should I do? Write a query or change the datatype in the table design view? How? Also which version of Visual Studio will be useful to modify the client user web form currently built with .NET Framework 1.1.4322? Please Advise me.
