insert into tables with linked columns

How do I insert into a table after I insert a linked column into it?

e.g.

t:( id:101 102 103 104; v:1.1 2.2 3.3 4.4)

update parent:t!id?101 101 102 102 from t

q)t

id  v   parent


101 1.1 0

102 2.2 0

103 3.3 1

104 4.4 1

q)`t insert (103;3.2)

'length

q)`t insert (103;3.2;0N)

't


Thanks. I still can’t figure out how to insert into a table (containing the link) from another table and update the link.
e.g.
t1:( c1:sym?cba; c2: 10 20 30)

t2:( c3:sym?aba`c; c4: 1. 2. 3. 4.)

update t1link:t1!t1.c1?c3 from t2

t3:( c3:sym?def`g; c4: 1. 2. 3. 4.)

Now, how do I  insert t3 records into t2.

Never mind I figured it out. I can do this -

t2 insert select c3,c4,t1link:t1!t1.c1?c3 from t3
