maxdb_field_seek

Set result pointer to a specified field offset (PECL maxdb:1.0-7.6.00.38)
bool maxdb_field_seek ( resource result, int fieldnr )

Procedural style:

Object oriented style (method):

result {
  bool field_seek(int fieldnr);
}

Sets the field cursor to the given offset. The next call to maxdb_fetch_field() will retrieve the field definition of the column associated with that offset.

Note:

To seek to the beginning of a row, pass an offset value of zero.

Return Values

maxdb_field_seek() returns previuos value of field cursor.

Examples

Example 1206. Object oriented style

<?php
$maxdb
= new maxdb("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
 
printf("Connect failed: %s\n", 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\n", $finfo->name);
 
printf("Table:    %s\n", $finfo->table);
 
printf("max. Len: %d\n", $finfo->max_length);
 
printf("Flags:    %d\n", $finfo->flags);
 
printf("Type:     %d\n\n", $finfo->type);

 
$result->close();
}

/* close connection */
$maxdb->close();
?>


Example 1207. Procedural style

<?php
$link
= maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
 
printf("Connect failed: %s\n", 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\n", $finfo->name);
 
printf("Table:    %s\n", $finfo->table);
 
printf("max. Len: %d\n", $finfo->max_length);
 
printf("Flags:    %d\n", $finfo->flags);
 
printf("Type:     %d\n\n", $finfo->type);

 
maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);
?>


The above examples would produce the following output:

Name:     NAME
Table:
max. Len: 10
Flags:    -1
Type:     2
