How to get the data from CRecordSet?

Question

3.00/5 (1 vote)

See more:

CRecordset rs(db);
    rs.Open(CRecordset::snapshot,SqlStr,CRecordset::readOnly);
    CDBVariant ip;
    //rs.GetFieldValue(ip);
    int Index;
    Index=12;
    rs.GetFieldValue(Index,ip);

I am using the above code. But rs.GetFieldValue gives exception. I want to take the ip address from the database where it is stored as varchar in database. Please help me.
