I have a treeview
that is rendered from Kartik Tree Manager. Below is my tree view
Table
What I want to do?
I want to select all the child nodes of Floor-1
via MySQL
query
I have tried to run a query like below
SELECT * FROM `mdc_node` m
WHERE m.`lft` = 11-2
Output
Desired Output
I want the following output
------------------------------------------------------------
| `id` | `root` | `lft` | `rgt` | `lvl` | `name` | 'icon' |
------------------------------------------------------------
| 3 | 1 | 3 | 4 | 2 |GIS Office| folder |
| 4 | 1 | 5 | 6 | 2 | Ali | user |
| 5 | 1 | 7 | 8 | 2 | Usman | user |
| 6 | 1 | 9 | 10 | 2 | Faisal | user |
------------------------------------------------------------
Below is my SQL Fiddle
I want to select all the child nodes under the parent node
I want to select all the child nodes of Floor-1 via MySQL query
I want the following output
select * from mdc_node;
SELECT t1.id, t1.root, t1.lft, t1.rgt, t1.lvl, t1.name, t1.icon
-- from 1st copy of a table
FROM mdc_node t1
-- join 2nd copy of a table used for to get the info about needed parent
JOIN mdc_node t2
-- child nodes left and right are between left and right of their parent
ON t1.lft BETWEEN t2.lft AND t2.rgt
-- we need only the next level
AND t1.lvl = t2.lvl + 1
-- specify parent
WHERE t2.name = 'Floor-1';
The only problem - I cannot understand why icon
for a row id=3
is 'folder'
in output whereas it is 'user'
in source data.
