Import xx.sql file to execute by using Ebean - sql

Question

Is there any way to execute SQLs directly read from SQL files(xx.sql) in Ebean?
For example, if I had a SQL file including several SQL statements (values already written in the file), is there any way to execute this SQL file by using Ebean?

Answer 1

You have at least two options out of the box:
Play evolutions are meant to updating DB schema, so you can use them also for inserting initial data (if they are flat, and will not contain relations to the objects not created yet), sample evolution for MySQL:
# --- !Ups
INSERT INTO your_table (some_field) VALUES ('New value');
# --- !Downs
DELETE FROM your_table WHERE some_field = 'New value`;
Use Global object and insert initial data using common Ebean's way:
public void onStart(Application app) {
if (YourModel.find.findRowCount() == 0) {
YourModel newItem = new YourModel();
newItem.someField = "New value";
newItem.save();
YourModel newItem2 = new YourModel();
// etc....
}
}
For the second approach you can check the way how to read YAML file holding initial data with Global object of Zentask sample (the file with sample is placed in conf directory)
Edit:
Take a closer look to the initial-data.yml, there are also relations between tasks and projects, so they have fixed id values. So you need do the same in your yaml:
projects:
- !!models.Project
id: 1
name: Play 2.0
folder: Play framework
tasks:
- !!models.Task
title: Fix the documentation
done: false
folder: Todo
project: !!models.Project
id: 1
