Re: event_scheduler ?

The event_Scheduler is, a way to Schedule Events (in this case queries) to run in MySQL at a given time. It is simply waiting for an event to trigger it.

Re: Linux fetchmail showing error

The certificate on your server is part of a chain. Many time the are delivered as separated files. Something like : server.cert and server.ca-bundle For dovecot, it easier to put them 1 file (order is important ! ).

Re: PHP Fatal error: Uncaught mysqli_sql_exception: Duplicate entry

You first should check why you have a duplicated key. You can use INSERT IGNORE command rather than the INSERT command. If a record doesn't duplicate an existing record, then MySQL inserts it as usual. If the record is a duplicate, then the IGNORE keyword tells MySQL to discard it silently without g...

Re: change primary key

You first have to drop the current primary key,
and after create a new.
Best is to do it in 1 SQL alter statement.

Code: Select all

ALTER TABLE table_name DROP primary key, ADD primary key(k1, k2, k3);
