I'm using the 4.45.13 version of the driver, with BDS 2007 and MSSQL 2005 (Enterprise/Express).
When I post data to database, I receive this error message: "string or binary data would be truncated".
Analising on SQL profiler the instructions sended, I verified that varchar fields are posted with an additional blank space on the sql instruction, exceding the original size of the field, generating the error.
I changed several options on the driver (UseUnicode, TrimFixedChar, etc.)
but nothing of that worked.
