the problem------
table1 has 2 fields
1.id int (primary key)
2.datastrings (varchar)
datastrings field has 3 rows
string1="-1,1,1,-1,1,1"
string2="1,1,-1,1,-1,-1";
string3="-1,-1,1,1,1,1"
how to fill another table2 ( which have same structure as table1)
so that the value in datastrings field in table2 is
added from the accumulated value from rows above it
so the value in table2 are
string1="-1,1,1,-1,1,1"
string2="0,2,0,0,0,0";
string3="-1,1,1,-1,1,1"
