hi,
i have a table consisting of 4 integers.
seq is for making the table ordered. (ORDER BY SEQ ASC)
a,b,c maybe null
seq | a | b | c
-----+----+----+---
0 | 1 | 2 | 3
1 | 1 | 2 |
2 | 5 | 7 |
3 | -2 | -4 |
i am needing a sql statement to do
c=a+b+"the c of the row with seq one less than myself"
this statement has to run over the whole table, in seq order.
how can this be acomplished???
cu&thanks
erik
