Hi Pavel,
Using this as reference and your link :
https://dba.stackexchange.com/questions/3281/how-do-i-use-currval-in-postgresql-to-get-the-last-inserted-id
I tried :
select lastval('t_id') from table_tutor;
but it is not working.
Is there any tutorial out there that teaches the exact syntax ?
Thanks & regards,
Karen

Hi,
I hope I am posting on the right forum. I googled but I can't find any solution pertaining to my problem.
Could someone know what is the syntext for last_insert_id() in Postgresql for me to insert into my sql execute query?
Postgres has not last_insert_id function. Maybe you think "lastval" function
Regards
Pavel
public int getTutorById() {
openConnection();
int tutor_id = 0;
try {
Statement stmt3 = connection.createStatement();
ResultSet rs = stmt3.executeQuery("SELECT last_insert_id() from xtutor");
{
while (rs.next()) {
tutor_id = rs.getInt(1);
}
}
} catch (SQLException e) {
e.printStackTrace();
}
return tutor_id;
}

The generated id is successfully generated by JDBC.
The errors when I tested in out using PGAdmin4 is
