Constant variable in control file - sqlldr

Question

Hi all,
Is there a way to create a dynamic constant variable within the control file?
I'm trying to load from a csv file but need just 2 values from the 1st row, as a constant for the inserts for the rest of the rows.
How/can I use a variable and assign this value to it and use that variable inside the control file?
For example: (first character: 1=header, 2=content)
.csv file:
1,constant1,constant2
2,data11,data12
2,data21,data22
2,data31,data32
2,data41,data42
table:
col1 col2 col3 col4
data11 data12 constant1 constant2
data21 data22 constant1 constant2
data31 data32 constant1 constant2
data41 data42 constant1 constant2
Thank you soo much for your help

Answer 1

I am thinking about the following:
1. Load the data into 2 separate tables (header and content)
2. Update the content with the constant value from header.
Question:
Is there any other better way that I can do? Like can those 2 steps be done in a single control file?
Pls help.
====================================================
Step 1:
load data
infile 'test.txt'
append
into table zz_test_hdr
when (1:1) = '1'
( constant_1 POSITION(2:12) ,
constant_2 POSITION(13:23))
into table zz_test
when (1:1) = '2'
( col_1 POSITION(2:11),
col_2 POSITION(12:22))
Step 2:
update zz_test
set (col_3, col_4) = (select constant_1,constant_2 from zz_test_hdr);
