               }
             }

my problem is i want to retrieve a column from the table "2-1subjects", that contains a coumn such as

2-1sub#1 2-1sub#2 2-1sub#3 2-1sub#4 2-1sub#5 2-1sub#6 2-1sub#7 2-1sub#8

Now i want to insert the same column in same order into the table "2-1".

but it inserted in reverse order such as

2-1sub#8 2-1sub#7 2-1sub#6 2-1sub#5 2-1sub#4 2-1sub#3 2-1sub#2 2-1sub#1. I don't know the reason. please tell me and correct my code. Thanks in advance
