maxdb_field_tell
(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() .
Return Values
Returns current offset of field cursor.
Example 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
