return 0;res = mysql_store_result (& db);// store the result set
}



IF (RES == NULL)

}

// repeat reading line, and the output value of the first field, until the row is NULL
the while (row = mysql_fetch_row (RES) )
{
the printf ( "% S% S% S% S \ n-", Row [0], Row [. 1], Row [2], Row [. 3]);
}

// set the result release
mysql_free_result (RES);
/ / close connection Mysql
