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

copy to clipboard

<?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

copy to clipboard

<?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:

copy to clipboard

Name:     NAME

Table:

max. Len: 10

Flags:    -1

Type:     2
