Try wxDb instead:

i getting blur...
what is the different between wxDB and wxODBC?

do you have any example?

whats going on with this, when i called like this?

wxDb *dbms;

     if (dbms->isOpen()) {
            ...
     }

it prompt me: "no matching function for call to "wxDB::isOpen()" ?

Thank you

That link is to wxDatabase doc, have you checked?

"A much more robust and feature-rich set of ODBC classes is now available and recommended for use in place of the wxDatabase class.

See details of these classes in: wxDb, wxDbTable"

Doc says, IsOpen(), not isOpen().

Wow... case sensitive... @@"

so, it seems like wxDB powerful than wxODBC?

Thank you.

class odbcSQL {
private:
        wxDb *dbms;
};

.....
...

    if (!dbms->ExecSql(sqlString.c_str())){
        countRow=0;
        return countRow;
    }

why it prompt me this error message ?
[Link Error] undefined reference to wxDb::ExecSql(wxString const&)"

Thank you.

".c_str" is not necessary.
Don't know what's wrong actually this time if your lib is OK.
