Description
Procedural style:
int maxdb_field_tell
( resource $result
)
Object oriented style (property):
result
int
$current_field
;
Returns the position of the field cursor used for the last maxdb_fetch_field() call. This value can be used as an argument to maxdb_field_seek().
Return Values
Returns current offset 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\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = $maxdb->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
/* get fieldpointer offset */
$currentfield = $result->current_field;
printf("Column %d:\n", $currentfield);
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 #2 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, $query)) {
/* Get field information for all fields */
while ($finfo = maxdb_fetch_field($result)) {
/* get fieldpointer offset */
$currentfield = maxdb_field_tell($result);
printf("Column %d:\n", $currentfield);
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:
Column 1: Name: NAME Table: max. Len: 10 Flags: -1 Type: 2 Column 2: Name: CNO Table: max. Len: 4 Flags: -1 Type: 0
