# Database Bremen Calling

## Server

mariadb v 10

## Getting started

- Execute 'create_schema.sql' and import 'sample_data.sql'

If the database is updated or changed, please update these files.
To avoid errors, it is best to drop the entire database, edit the create script and re-import the sample data.

## Creating the dump file

```bash
mysqldump -u [username] -p --no-create-info --complete-insert bremen_calling > sample_data.sql
```

## Removing existing tables

We want only to remove the tables in order to preserve user privileges

```sql
SELECT concat('DROP TABLE IF EXISTS `', table_name, '`;')
FROM information_schema.tables
WHERE table_schema = 'bremen_calling';
```

outputs complete drop statements

```sql
SET FOREIGN_KEY_CHECKS = 0;
-- Your semicolon separated list of DROP statements here
DROP TABLE IF EXISTS `notification`;
DROP TABLE IF EXISTS `role`;
DROP TABLE IF EXISTS `ship`;
DROP TABLE IF EXISTS `participant`;
DROP TABLE IF EXISTS `times`;
DROP TABLE IF EXISTS `role_securable_map`;
DROP TABLE IF EXISTS `user_role_map`;
DROP TABLE IF EXISTS `user`;
DROP TABLE IF EXISTS `securable`;
DROP TABLE IF EXISTS `shipcall_participant_map`;
DROP TABLE IF EXISTS `berth`;
DROP TABLE IF EXISTS `shipcall`;

SET FOREIGN_KEY_CHECKS = 1;
```
