Extracting differences between two columns dataset (SQL command)

Applications Programming

Hi,

I have a table in my sqlite, here is an example (tab separated)

585     name1 chr1    +       1872    3533    3533    3533    6       1872,2041,2475,2837,3083,3315,  1920,2090,2560,2915,3237,3533,  name2

The 10th and 11th columns have information in a comma separated format (not tab).

1872,2041,2475,2837,3083,3315,  1920,2090,2560,2915,3237,3533,

.

I want to know if there's a sql command I can use to find the difference between the first value of column 10 and the first value in column 11, and the same for the second column, etc.?

for example
1920-1872
2090-2041
2560-2475
.
.
.
3533-3315

Thanks
