h2-functions-4-mysql
======================
H2 User defined functions for MySQL.
# Why this project?
I always use H2 for unit test instead of real MySQL(Docker), but some MySQL functions are not available in H2. So I create this project to define some functions for MySQL and make
unit test easy.
# How to use?
In you pom.xml add following dependency:
For H2 1.4.x, please use 1.0.0 version as following:
```xml
org.mvnsearch
h2-functions-4-mysql
1.0.0
```
For H2 2.0.x, please use 2.0.0 version as following:
```xml
org.mvnsearch
h2-functions-4-mysql
2.0.0
```
* Flyway with Spring Boot: automatically(classpath:db/migration/h2/V0_functions.sql), no configuration.
* Manual: Add following code in your application. datasource is h2 datasource.
```
H2FunctionsLoader.loadMysqlFunctions(dataSource);
```
* From H2 210, and you can use INIT parameter to load functions automatically.
```
String jdbcUrl = "jdbc:h2:mem:sample;INIT=RUNSCRIPT FROM 'classpath:db/migration/h2/V0_functions.sql'";
String jdbcUrl2 = "jdbc:h2:mem:sample;INIT=RUNSCRIPT FROM 'classpath:db/migration/h2/V0_functions.sql';RUNSCRIPT FROM 'classpath:your_script.sql'";
```
