Question

Is it possible to increase the PK somehow?
I need to make it start at about 10000. Is there some sql statement I could execute directly in phpMyAdmin?

EDIT:
I need to be a bit more clear…

I need to update all rows with a PK over 2190 (about 2000 rows). Need to update them to start at about 10000 instead… So I do believe it is some sort of programming question…

Answer 1

Quoting the doc.

So the question is about updating some set of values. Well, here’s one way to do it:

UPDATE some_table 
   SET some_pk = 10000 + some_pk 
 WHERE some_pk > 2190

Still, you have to follow this with ALTER TABLE tbl AUTO_INCREMENT = 10000; otherwise all the rows inserted after this UPDATE still get an old auto_increment. For example:

CREATE TABLE t (id INT AUTO_INCREMENT NOT NULL, s VARCHAR(5), PRIMARY KEY (id));
INSERT INTO t (s) VALUES ('a'), ('b'), ('c'), ('d'), ('e');

UPDATE t SET id = id + 10000 WHERE id > 3;
ALTER TABLE t AUTO_INCREMENT = 10000;

INSERT INTO t (s) VALUES ('f');

Without ALTER TABLE... 'f'‘s id will be 6; with it – 10006.

Here’s SQL Fiddle illustrating this concept.
