Re: FreeTDS problems with converting SQL BigInt

I am using odbc.

I know 0.64 is not supported, but I dont have the liberty to upgrade. I could make a case for upgrading if this bug is fixed in 0.82.

Is this a known bug that was fixed in 0.82?

Thanks

feroze.

Which library (ctlib, dblib, odbc) are you using ?

FreeTDS 0.64 ?? Sorry, not supported anymore.
