I am not sure what wstrcpy you are using, but


will create a array of 4 byte characters. unixODBC by default, will use the 2 byte UNICODE as odbc does on windows, so you could try something like

void wstrconvert( SQLWCHAR *out, char *in ) {
        while( *in ) {
                *out++ = *in++;
        *out = 0;


memset( connectionInfoBuffer, 0, 1024);

And a further problem, you call

SQLGetDiagRecW( SQL_HANDLE_DBC, hdbc, i, sqlstate,
&sqlcode, message, 10000, &length)

but then call

printf( "SQLSTATE          = <%s>\n", sqlstate ) ;

Again, sqlstate and message will be a two byte UNICODE string.
