LOAD csv file with specified column values - database

Question

I have 2 csv files that contains 4 cols(c1,c2,c3,c4) and created a table that contain 5 columns (a1,a2,a3,a4,a5).
Now I want to load those two files into the tables separately such that for each time I can have a contant value that goes in a1 column of the table.
Values in csv file 1
c1,c2,c3,c4
............
1 2 3 4
1 2 3 4
1 2 3 4
1 2 3 4
Values in csv file 2
c1,c2,c3,c4
............
5 6 7 8
5 6 7 8
5 6 7 8
5 6 7 8
resulting table should be
a1, a2, a3, a4 ,a5
..................
my_value1 1 2 3 4
my_value1 1 2 3 4
my_value1 1 2 3 4
my_value1 1 2 3 4
my_value2 5 6 7 8
my_value2 5 6 7 8
my_value2 5 6 7 8
my_value2 5 6 7 8
I tried this but clearly doesn't work and I read the load documentation from the IBM site but I wasn't able to find anything.
load from path\file1 of del insert into table_name(my_value1, c1,c2,c3,c4)
load from path\file2 of del insert into table_name(my_value2, c1,c2,c3,c4)

Answer 1

You have got some good suggestions in the comments, so this is just another way to do it:
db2 "create table target(a1 varchar(20) not null, a2 int, a3 int, a4 int, a5 int)"
db2 "alter table target alter column a1 set default 'my_value1'"
db2 "load from ./f1.csv of del insert into target (a2,a3,a4,a5)"
db2 "alter table target alter column a1 set default 'my_value2'"
db2 "load from ./f2.csv of del insert into target (a2,a3,a4,a5)"
db2 "alter table target alter column a1 drop default"
db2 "select * from target"
A1 A2 A3 A4 A5
-------------------- ----------- ----------- ----------- -----------
my_value1 1 2 3 4
my_value1 1 2 3 4
my_value1 1 2 3 4
my_value1 1 2 3 4
my_value2 5 6 7 8
my_value2 5 6 7 8
my_value2 5 6 7 8
my_value2 5 6 7 8
