(no version information, might be only in CVS)
result->current_field --
Get current field offset of a result pointer
Description
Procedural style:
int
maxdb_field_tell ( resource result )
Object oriented style (property):
class
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().
返回值
Returns current offset of field cursor.
Example
例子 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();
?>

例子 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 |
