CREATE TABLE _TREE_ (our key components are
id int(11) NOT NULL auto_increment,
parent_id int(11) NOT NULL DEFAULT 0,
seqid int(11) NOT NULL DEFAULT 0,
depth int(11) NOT NULL DEFAULT 0,
leaf int(1) NOT NULL DEFAULT 0,

fullpath TEXT default '',
PRIMARY KEY (`id`),
INDEX qlookup( parent_id , seqid , depth)

This does the hard work of iterating through the tree, and updating the sequence number, depth, leaf field and filling in the fullpath field

You can now create a generic tree code by replacing my _TREE_ word with your table name:
DROP FUNCTION IF EXISTS _TREE__add_node;
DELIMITER $$
CREATE FUNCTION _TREE__add_node(
i_parent INT(11),
i_after INT(11),
i_name VARCHAR(128)
) RETURNS INT(11) DETERMINISTIC
BEGIN
DECLARE v_depth INT(11);
DECLARE v_seqid INT(11);
DECLARE v_ret INT(11);
DECLARE v_tmp INT(11);
SET v_depth = 0;
SET v_seqid = 0;
SET v_ret = 0;
SET v_tmp = 0;
#// grap parent depth.
SELECT depth +1, seqid + 1 INTO v_depth, v_seqid FROM _TREE_ WHERE id= i_parent LIMIT 1;
#// grab previous id..
IF i_after > 0 THEN
SELECT seqid INTO v_tmp FROM _TREE_ WHERE id = i_after AND parent_id = i_parent LIMIT 1;
IF v_tmp > -1 THEN
SET v_seqid = v_tmp+1;
END IF;
END IF;
INSERT INTO _TREE_ SET
depth = v_depth ,
seqid = v_seqid ,
parent_id = i_parent,
name = i_name;
SELECT LAST_INSERT_ID() INTO v_ret;
#// fix the seqend id
UPDATE _TREE_ SET seqid = seqid +1 WHERE seqid >= v_seqid AND id != v_ret;
RETURN v_ret;
END $$

#sed -e "s/_TREE_/yourtable/g" tree.js | mysql yourdb -fOnce all that is done the SQL to create tree nodes is very simple:
delete from nametree; alter table nametree AUTO_INCREMENT =1 ;Gives you a nice little table
select nametree_add_node(0,0, 'one at top');
call nametree_resequence(':');
select nametree_add_node(1,0, 'two on one');
call nametree_resequence(':');
select nametree_add_node(1,0, 'three on one (first)');
call nametree_resequence(':');
select nametree_add_node(1,2, 'four on one (last)');
call nametree_resequence(':');
select nametree_add_node(0,1, 'five on top (last)');
call nametree_resequence(':');
select nametree_add_node(0,0, 'six is first');
call nametree_resequence(':');
SELECT * FROM nametree ORDER BY seqid;
Enjoy tree.js (I name my mysql stored procs as js, just so my editor works better with them)

As my thumbs are twiddling waiting to see if projects start coming in next year, I thought I'd do a roundup of this years projects (open and closed). I was pondering if everyone else was seeing the effects of the recession, so I'd be interested to hear if you've also seen work slacking off.
Let's hope next year we see some more life from the Sales and Marketing, as my current reliance on word of mouth, may not keep feeding my mouth at this rate.
Anyway Merry Christmas and Happy new year to all.
Read on for my Year of Projects
x = this.createXMLHttpRequest();Since x was an object, it could not be checked against a boolean (even though this works perfectly on Firefox)
if (x != false) {
document.getElementsByTagNameNS('*'',"rows");used to grab sections of the Gnumeric template file, much to my amazement (well less so by now), I realized that IE doesnt actually implement DOM!!! (or DOM3 AFAIK) properly...
