      CString Str;
      Str.Format( _T( "SELECT EmployeeID,Salary FROM EMPLOYEE WHERE EmpName=%s" ), _T( "tejaswini" ));

      SQLCHAR SQL[] = Str; // Maybe you will have to convert this Str to SQLCHAR type.

        because the SQL engine is executing such query, as is. it is then searching Str as the Employee name...

          Si Str va en el texto entrecomillado el ordenador lo interpreta como texto y no como tu variable. Desconozco como funciona un SQLCHAR, si el texto fuera un CString deberías ponerlo así... "SELECT EmployeeID, Salary FROM EMPLOYEE WHERE EmpName='" + Str + "´"; En este caso si cambiará Str por el valor de tu variable, además recuerda que en la sentencia Where EmpName= algo, ese algo tiene que ir entre comillas simples. Espero haberte ayudado.
