I am upscaling an access 2003 database to SQL Server Express 2008. The tables appear to be created ok and the data looks ok.
I have an MFC application that connects to this database. It worked fine connecting to access, but when I connect to SQL Server I am getting the following error on a select statement.
DBMS: Microsoft SQL Server
Version: 10.50.1600
ODBC Driver Manager Version: 03.80.0000
Warning: ODBC Success With Info on field 0.
String data, right truncation
State:01004,Native:0,Origin:[Microsoft][ODBC SQL Server Driver]
The data that is returned should be 8 characters but is only 7 with the right most character truncated.
The access front end can read the data from SQL Server correctly.
The field in the SQL Server table is defined as nvarchar with a length of 8.
The code to read the field looks something like
CDatabase Database;
CString sSerialNumber = "00000000";
CString SqlString;
CString sDsn = "Driver={SQL Server};Server=server\\db;Database=Boards;Uid=uid;Pwd=pwd;Trusted_Connection=False";
Database.Open(NULL,false,false,sDsn);
CRecordset recset( &Database );
SqlString.Format("Select SerialNumber from boards where MACAddress = '%s'",mac);
recset.Open(CRecordset::forwardOnly,SqlString,CRecordset::readOnly);
recset.GetFieldValue("SerialNumber",sSerialNumber);
After this, sSerialNumber should be 12345678 but its 1234567
Thanks for the help
I’d agree that this is driver related. The {SQL Server} driver was introduced for use with SQL 2000. {SQL Native Client} came along with 2005. Ideally, for your 2008 database, you should use the newest {SQL Server Native Client 10.0}. The newer drivers are backward compatible with older versions of SQL Server.
