- by teutara
I know it is super noob and will be answered in no time, but I could not figure.. sorry for any inconvenience..
Here is the thing:
ID colA colB Length
1 seq1 seq11 1
2 seq1 seq11 11
3 seq3 seq33 21
4 seq3 seq33 14
I have a db with this kind of a table, has more than 10M rows. I want to loop though colA…
