SCENARIO
ALTER TABLE {TABLE NAME} AUTO_INCREMENT = 1;
INSERT INTO {TABLE NAME} ({COLUMN}) VALUES (1); (this is only record in table after auto increment was updated)
SELECT AUTO_INCREMENT FROM information_schema.TABLES WHERE TABLE_SCHEMA = {DATABASE NAME} AND TABLE_NAME = {TABLE NAME};
the last select auto_increment is returning the old value before execution alter table in step 1) and I don't understand why and hot to fix it or maybe alter table in step 1) is not correct way to reset auto_increment.
THX
PS. I know a bit but not everything. I was researching this problem and didn't find satisfactory/explanatory answer.
I guess you must set AUTO_INCREMENT = 1 not 0
The INFORMATION_SCHEMA doesn't update to reflect recent alterations. MySQL 8.0 changed it so it only updates once every 24 hours.
You can set this:
SET GLOBAL information_schema_stats_expiry=0;
That will make INFORMATION_SCHEMA update immediately, at the cost of some overhead on your system.
