I want to sort alphabetically on the first field and sort in descending numerical order on the 2nd field. With a normal "sort -r -n" it does this:
abc ||| 5e-05 ||| bla
abc ||| 3 ||| ble
def ||| 1 ||| abc

MAXDB_FIELD_SEEK(3) 1 MAXDB_FIELD_SEEK(3)
maxdb_field_seek - Set result pointer to a specified field offset
Procedural style
SYNOPSIS
bool maxdb_field_seek (resource $result, int $fieldnr)
DESCRIPTION
Object oriented style
bool maxdb_result::field_seek (int $fieldnr)
Sets the field cursor to the given offset. The next call to maxdb_fetch_field(3) will retrieve the field definition of the column associ-
ated with that offset.
Note
To seek to the beginning of a row, pass an offset value of zero.
RETURN VALUES
maxdb_field_seek(3) returns previuos value of field cursor.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = $maxdb->query($query)) {
/* Get field information for 2nd column */
$result->field_seek(1);
$finfo = $result->fetch_field();
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
$result->close();
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = maxdb_query($link, $query)) {
/* Get field information for 2nd column */
maxdb_field_seek($result, 1);
$finfo = maxdb_fetch_field($result);
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Name: NAME
Table:
max. Len: 10
Flags: -1
Type: 2
