bool maxdb_field_seek ( resource $result, int $fieldnr )
Procedural style
Object oriented style
bool maxdb_result::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.
Returns:
maxdb_field_seek() returns previuos value of field cursor.
Examples:
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(); ?>
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); ?>
