Here’s some good documentation on PHP prepared statements and stored procedures including how to call stored procedures with output parameters.
You can disable foreign key checks with
SET foreign_key_checks = 0;
And you can disable unique index checks with
SET unique_checks = 0;
I read The Next Gen Database Servers Powering Let’s Encrypt which mentioned how they tuned ZFS.
Today I discovered sequences in MariaDB. Gonna take them for a spin!
To generate an SSL private key for use with MySQL/MariaDB and PDO:
openssl genrsa -out client-key.pem 4096
By default when you run a dump with ‘mysqldump’ the date of the dump is appended to the file, e.g.:
jj5@love:~/desktop/experiment$ udiff * --- dbt__jj_dev_1__svn_jdrepo.1.sql 2019-06-11 18:11:13.267758230 +1000 +++ dbt__jj_dev_1__svn_jdrepo.2.sql 2019-06-11 18:12:03.856075974 +1000 @@ -32,4 +32,4 @@ /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; /*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */; --- Dump completed on 2019-06-10 21:59:44 +-- Dump completed on 2019-06-10 12:06:49
This causes dumps for a single database that has not changed to have two dumps which differ. It’s better to have dumps from the same unchanged database to be the same. To facilitate that add the –skip-dump-date option when running ‘mysqldump’.
See here for the back-story.
