问题 I did some testing with floating point calculations to minimize the precision loss. I stumbled across a phenomen I want to show here and hopefully get an explanation. When I write print 1.0 / (1.0 / 60.0) the result is 60.0024000960 When I write the same formula and do explicit casting to float print cast(1.0 as float) / (cast(1.0 as float) / cast(60.0 as float)) the result is 60 Until now I thought that numeric literals with decimal places are automatically treated as float values with the

To disable this message for all of an sqlcmd session, use the -m commandline option: sqlcmd -m 1 <other options> To disable this message for a block of code, use the :setvar batch

问题 We store documents in an SQL Server 2005 database table with a column format of "Image". Every time I try to store a PDF file which is greater than 1 Meg, it somehow gets corrupted. Is there any particularly efficient method in .NET to serialize and store large files (~10megs) into a database?
