# MyVC (MySQL Version Control)
Utilities to ease the maintenance of MySQL database versioning using a Git
repository.
## Prerequisites
Required applications.
* Git
* Node.js = 12.17.0 LTS
* Docker
## How to use
Export structure (uses production configuration).
```
$ myvc structure
```
Export fixtures (uses production configuration).
```
$ myvc fixtures
```
Export routines.
```
$ myvc routines [environment]
```
Apply changes into database.
```
$ myvc apply [-f] [-u] [environment]
```
## Basic information
Create database connection configuration files for each environment at main
project folder using the standard MySQL parameters. The predefined environment
names are *production* and *testing*.
```
db.[environment].ini
```
Structure and fixture dumps are located inside *dump* folder.
* *structure.sql*
* *fixtures.sql*
* *fixtures.local.sql*
Routines are located inside *routines* folder. It includes procedures,
functions, triggers, views and events with the following structure.
```
routines
`- schema
|- events
| `- eventName.sql
|- functions
| `- functionName.sql
|- procedures
| `- procedureName.sql
|- triggers
| `- triggerName.sql
`- views
`- viewName.sql
```
## Versions
Place your versions inside *changes* folder with the following structure.
```
changes
|- 00001-firstVersionCodeName
| |- 00-firstExecutedScript.sql
| |- 01-secondScript.sql
| `- 99-lastScript.sql
`- 00002-secondVersion
|- 00-firstExecutedScript.sql
`- 00-sameNumbers.sql
```
## Built With
* [Git](https://git-scm.com/)
* [nodejs](https://nodejs.org/)
* [docker](https://www.docker.com/)
