How to read the first column in a flat file with ~ as delimiter
I have one flat file like below

id1~col~batch1
id2~col2~batch2
id3~col3~batch3

I need to read the first column one by one and I need to write one db2 query based on that column1
Like
for (i=0;i<=10;i++)
do
insert into table column (con_id) values (select column from table where id=$i)
done<input_file

Here i should be id1,id2 & id3 etc...
something like this..
Can you please help me in reading the first column of the flat file and how can I use that value in the query.

Thanks in advance.

Code:
while IFS='~' read i x; do
  echo "insert into table column (con_id) values (select column from table where id=$i)"
done<infile

Code:
insert into table column (con_id) values (select column from table where id=id1)
insert into table column (con_id) values (select column from table where id=id2)
insert into table column (con_id) values (select column from table where id=id3)

Ok, by awk:

Code:
$ awk -F"~" '{print "insert into table column (con_id) values (select column from table where id="$1")"}' urfile
insert into table column (con_id) values (select column from table where id=id1)
insert into table column (con_id) values (select column from table where id=id2)
insert into table column (con_id) values (select column from table where id=id3)
