Question

i am using CTE to manage my hierarchy data. Below is my select query

 WITH ctLevel
                AS
                (
                    SELECT
                        C_TASK_ID                                                               AS Child
                        ,P_Task_ID                                                              AS Parent

                    WHERE  
                        common_task_rel.C_TASK_ID = common_task.TASK_ID
                        and     common_task.[TASK_TYPE] = 'F' AND common_task.[MODULE_CODE] ='PRODE' AND common_task.[STATUS] <> 'D'
                        and     common_task_rel.P_TASK_ID is null

                    UNION ALL

                    SELECT 
                        C_TASK_ID                                                                   AS Child

                        [COMMON.TASK_REL]as common_task_rel
                    INNER JOIN 
                        ctLevel
                    ON 
                        ( P_Task_ID = Child ) ,
                        [COMMON.TASK] as common_task

                    WHERE  
                            common_task_rel.C_TASK_ID = common_task.TASK_ID
                    and     common_task.[TASK_TYPE] = 'F' AND common_task.[MODULE_CODE] = 'PRODE' AND common_task.[STATUS] <> 'D'
                    )

                   SELECT [Parent] ,[Child],taskSeq, Level,[taskOrder],Task_Name,[TASK_POSITION]
                    FROM   ctLevel  
                    order by [taskOrder],[Level],[TASK_POSITION]

How my result look like:

You may c the example.The
10
10.1
10.1.1
10.1.1.1 suppose will be at the bottom of the 9

Is it possible to sort those record like below

1
2
2.1
2.2
2.4
2.5
2.6
2.7
3
3.1
3.2

9
9.1
9.1
9.1.1
9.1.1.1
9.1.1.2
9.1.1.3
9.1.1.4

10
10.1
10.1.1
10.1.1.1

Thanks in advance.

Format the numbers like 001, for example:

right('000' + convert(varchar(max), [Level] + 1),3)
