Hi

I want to store numbers in my SQL Server database, how high can Int go?  Can you set an int to be unsigned as I only need to to be whole integers from 0 onwards.

I'm looking to store numbers anywhere from zero into the trillions.  I don't want to store it as a string and write my own add functions etc!  Numbers have to be accurate.

Thanks,

Tom

I don't think you can have unsigned integers the max field size for int is 12 so I assume the biggest number you can have is 999,999,999,999 not cetain though

EDIT: I think its 999,999,999 actually, as that is the highest value I can insert

Rats that's only 1 billion.  I really need a lot more than that.  Is the only way to get past this to store it as a string and write my own functions to do math on them?  That's going to be a royal pain in the ass.

Int can hold a max of 2,147,483,647
BigInt can hold a max of 9,223,372,036,854,775,807
If you need to go higher, you approximate numbers like 'real' and 'float' which go to 3.40E + 38 respectively 1.79E + 308

Thanks

I get mismatches when dealing with the bigints in ASP, what do I convert the bigint value from the database to?  Long?  Or is that not big enough.

You get errors if you try to do Integer math or BigInts via VBScript. IF you convert them to doubles via VBScript, then you should not have that problem.
