# Sorting substrings of different lengths numerically, part 2

Here is the rest of Rudy's answer. See part one.

Anyhow, this detailed explanation could go on for a lot longer, so I'll just jump ahead to the end and give you the full query --

``` SELECT IPno , RIGHT('00'& MID(IPno ,1 ,INSTR(IPno,'.')-1) , 3 ) , RIGHT('00'& MID(IPno ,INSTR(IPno,'.')+1 ,INSTR(MID(IPno ,INSTR(IPno,'.')+1) ,'.')-1) , 3 ) , RIGHT('00'& MID(IPno ,INSTR(MID(IPno ,INSTR(IPno,'.')+1) ,'.') +INSTR(IPno,'.')+1 ,INSTR(MID(IPno ,INSTR(MID(IPno ,INSTR(IPno,'.')+1) ,'.') +INSTR(IPno,'.')+1) ,'.')-1) , 3 ) , RIGHT('00'& MID(IPno ,INSTR(MID(IPno ,INSTR(MID(IPno ,INSTR(IPno,'.')+1) ,'.') +INSTR(IPno,'.')+1) ,'.') +INSTR(MID(IPno ,INSTR(IPno,'.')+1) ,'.') +INSTR(IPno,'.')+1) , 3 ) FROM IPtable ORDER BY 2, 3, 4, 5;
```

Ugly, isn't it? What a great candidate for a view!

``` CREATE VIEW IPnumbers (IPno, IP1, IP2, IP3, IP4) AS  the SELECT statement above, minus the ORDER BY clause
```

Then you could say

``` SELECT IPno, IP1, IP2, IP3, IP4 FROM IPnumbers ORDER BY IP1, IP2, IP3, IP4
```
