The code works in that sence that I get resultsets, the only thing that
does not work is the "ORDER BY" option for the SELECT statement. The
resultset is ordered by the exe column instead.
Should I run MyODBC instead?
Is the sourcecode for mysql.exe available?
Is there any miss-usage of mysql_query, mysql_store_result etc?
/Christer
void StatisticsToday()
{
char szSQL[1024];
MYSQL_RES* res; // Resultset
MYSQL_ROW row; // Row
int i, j;
// Tried both below
strcpy(szSQL, "SELECT DISTINCT exe, sum(duration) AS s FROM data
GROUP BY exe ORDER BY s DESC");
strcpy(szSQL, "SELECT DISTINCT exe, sum(duration) FROM data
GROUP BY exe ORDER BY 2 DESC;");
if (!mysql_query( myData, szSQL)) {
res = mysql_store_result( myData ) ;
i = (int) mysql_num_rows( res ) ;
while ( row = mysql_fetch_row( res ) )
{
j=mysql_num_fields( res );
sprintf(szId, "%s %s", row[0], row[1]);
}
mysql_free_result( res ) ;
} else {
printf( "Couldn't execute %s on the server !\n", szSQL )
;
}
}

command-line tool mysql.exe)
Then I would suggest you check your C code.
The program 'mysql' uses the C API.
