PostgreSQL set Next ID Sequence Value to MAX(id) from Table

postgresql-set-id-seq.sql

-- Get Max ID from table
SELECT MAX(id) FROM table;

-- Get Next ID from table
SELECT nextval('table_id_seq');

-- Set Next ID Value to MAX ID
SELECT setval('table_id_seq', (SELECT MAX(id) FROM table));

If sequence contains uppercase letters in name:
SELECT setval('"Foo"', 42);

Notice the double quotes inside the single quotes

Thanks!

Thanks for this.

Hello, it didn't fit me (if the table is empty, if I need to reset to the first value). I've made my own procedure based on it, maybe it can be helpful for somebody. https://urpylka.com/posts/post-15/

Thank you

Thank you!!

select setval('table_id_seq', max(id)) from table_name;  -- Next nextval will return  max(id) + 1

If sequence contains uppercase letters in name: SELECT setval('"Foo"', 42);

Notice the double quotes inside the single quotes

Thank you very much, that was really useful ! Spent hours... lol

Not always an issue, but worth noting: the value that it sets it to if there are no rows is 1 which results in the first invocation of nextval returning 2 and skipping 1.

Thanks !

Thank you!

thanks
