I have a table named `SIRKET` and two columns named `sirket_unvan` and `cust_id`. I want to find words in `sirket_unvan` which are longer than 15 characters.

I use 

```
select sirket_unvan from SIRKET where cust_id=0

```

But how can find word which are longer than 15 characters? I would like to report those words to another column. ı think ı should write procedure. And one line can be has 2 or more words which has longer than 15 characters 

```
 cust_id |sirket_unvan
---------+----------------------------------------------
  0      | sdsd Afdfdgfdgdgdg fdgfgfgf fgfgf           
  0      | dfdfds dffd dsfdffggfdgfdgfdgfgdgdfgd fdfdfd
  0      | sdfsdfsdf dsfdsfdsfdsdgfgfgf               
  0      | sdfsdfsd sdfsdfsdf
  1      | sdfsdfsdf dsfdsfdsfdsdgfgfgf 
  2      | dsfdsfs sdfsdfsdgfhfh

```

I want this output

```
   cust_id   | sirket_unvan                                |longerthan15characterwords
    ---------+---------------------------------------------+---------------------------

      0      | sdfsdfsdf dsfdsfdsfdsdgfgfgf                | dsfdsfdsfdsdgfgfgf

```
