C ++中的sqldriverconnect无法连接到本地数据库sql 2008

Question

can someone here kindly help? I am trying to connect to sql server 2008 in c++ by using SqlDriverConnect. Here is my code:

SQLTCHAR *srv = (SQLTCHAR *) "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=bbData;Data Source=NBK-EMMAY";
SQLRETURN rc = SQLDriverConnect(hdbc, NULL, srv, strlen((char*)srv),
                                (SQLWCHAR*)OutConnStr, 255, &OutConnStrLen, SQL_DRIVER_PROMPT);

Note, the srv string is created and verified by the .udl file. I have tried various options, but seems I can go nowhere. Many thanks in advance!

Answer 1

You using an OleDb connection string, not an ODBC connection string. SqlDriverConnect in an ODBC function, it won't work with an OleDb provider.

Try using the following connection string:

Driver={SQL Server Native Client 10.0};Server=JBK-EMMAY;Database=bbData;Trusted_Connection=yes;
