MyEMS Database

Introduction

Database schema and scripts for MyEMS.

Prerequisites

MySQL 8.0 (64bit) or later

or

MariaDB 10.5 (64bit) or later

or

SingleStore 7.0 or later

Installation

Execute the following scripts in MySQL commandline, or execute in other MySQL client tools such as MySQL Workbench, Navicat, DBaver, phpMyAdmin, etc.

cd myems/database/install
mysql -u root -p < myems_billing_baseline_db.sql
mysql -u root -p < myems_billing_db.sql
mysql -u root -p < myems_energy_baseline_db.sql
mysql -u root -p < myems_energy_db.sql
mysql -u root -p < myems_fdd_db.sql
mysql -u root -p < myems_historical_db.sql
mysql -u root -p < myems_reporting_db.sql
mysql -u root -p < myems_system_db.sql
mysql -u root -p < myems_user_db.sql

To insert demo data execute the following scripts,

cd myems/database/demo
mysql -u root -p < myems_system_db.sql

Change COLLATE for MySQL server before version 8.0

sudo nano /etc/mysql/my.cnf

[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

Fix MySQL Error: Got a packet bigger than 'max_allowed_packet' bytes

Change the my.cnf or my.ini file (usually found in /etc/mysql/) under the mysqld section and set:

max_allowed_packet=100M

or you could run these commands in a MySQL console connected to that same server:

set global net_buffer_length=1000000;
set global max_allowed_packet=1000000000;
