change data when update - sql

Question

I have two tables and when I make an insertion, I don't want to transfer data created, I want to put the sysdate. I have the next code:
create or replace procedure procedure1 as
begin
INSERT INTO tlp
(given_name,
namel,
email, sysdate)
SELECT first_name,
namel,
mail
FROM glob
WHERE ( NOT EXISTS (SELECT email
FROM tlp
WHERE glob.mail = tlp.email )
AND glob.mail IS NOT NULL )
OR ( NOT EXISTS (SELECT namel
FROM tlp
WHERE glob.namel = tlp.namel )
--AND glob.mail IS NULL
);
end procedure1;

Answer 1

create or replace procedure procedure1 as
begin
INSERT INTO tlp
(given_name,
namel,
email, sysdate)
SELECT first_name,
namel,
mail,
GETDATE() as sysdate
FROM glob
WHERE ( NOT EXISTS (SELECT email
FROM tlp
WHERE glob.mail = tlp.email )
AND glob.mail IS NOT NULL )
OR ( NOT EXISTS (SELECT namel
FROM tlp
WHERE glob.namel = tlp.namel )
--AND glob.mail IS NULL
);
end procedure1;

Answer 2

In your procedure for insert, number of columns given for table tlp is 4 and columns selected from table glob is 3.
If you want to insert sysdate for one column of table tlp, then mention the
column name and add sysdate in the select statement.
Assuming the table structure of tlp is
tlp (
given_name,
namel,
email,
date_created --if clmn name is not "date_created", then change it in the proc.
)
Now try this;
create or replace procedure
procedure1 as
begin
INSERT INTO tlp (
given_name, namel,
email, date_created
)
SELECT
first_name, namel,
mail, sysdate --note sysdate is given in select query
FROM glob
WHERE (
NOT EXISTS (
SELECT email
FROM tlp
WHERE glob.mail = tlp.email
)
AND glob.mail IS NOT NULL
) OR (
NOT EXISTS (
SELECT namel
FROM tlp
WHERE glob.namel = tlp.namel
)
--AND glob.mail IS NULL
);
end procedure1;
