Hello @pal_1990,

 

I think your input is something like this:

 

+----------------------------------------------------+
|                    semicolon.a                     |
+----------------------------------------------------+
| 1;13004211,13004211_02_13004212,4000000003378605589,1105,2000 |
+----------------------------------------------------+

1 . You need to separate the one from other values, for this I use posexplode fonction:

 

 

 

 

select pe.i,pe.x from semicolon lateral view posexplode(split(a,';'))  pe as i,x;
+-------+----------------------------------------------------+
| pe.i  |                        pe.x                        |
+-------+----------------------------------------------------+
| 0     | 1                                                  |
| 1     | 13004211,13004211_02_13004212,4000000003378605589,1105,2000 |
+-------+----------------------------------------------------+

 

 

 

 

2. You on only select where pe.i =1:

 

select t.x from 
(select pe.i,pe.x
from semicolon lateral view posexplode(split(a,';'))  pe as i,x) t where t.i=1 ;

+----------------------------------------------------+
| t.x |
+----------------------------------------------------+
| 13004211,13004211_02_13004212,4000000003378605589,1105,2000 |
+----------------------------------------------------+

 3. You split values in columns;

 

 

select split(t.x,',')[0] as col1,
       split(t.x,',')[1] as col2,
       split(t.x,',')[2] as col3,
       split(t.x,',')[3] as col4,
       split(t.x,',')[4] as col5
from 
(select pe.i,pe.x
from semicolon lateral view posexplode(split(a,';'))  pe as i,x) t where t.i=1 ;

+-----------+-----------------------+----------------------+-------+-------+
| col1 | col2 | col3 | col4 | col5 |
+-----------+-----------------------+----------------------+-------+-------+
| 13004211 | 13004211_02_13004212 | 4000000003378605589 | 1105 | 2000 |
+-----------+-----------------------+----------------------+-------+-------+

  

 

I hope it will help you.

Best regards
