Update site: http://romkuapps.com/Apps/SQLite/update
2. Create JSON file that describes your sqlite schema.
- Schema has
nameand tables tablehasname,descriptionand columnscolumnhasnameandcolumnTypecolumnTypecan beTEXTorINTEGERonly
Example: Two tables: STUDENT and COURSE
{
"name": "SQL_PRIVATE_DB",
"tables": [
{
"name": "STUDENT",
"description": "Student details",
"columns": [
{
"name": "FIRSTNAME",
"columnType": "TEXT"
}
,
{
"name": "LASTNAME",
"columnType": "TEXT"
}
,
{
"name": "AGE",
"columnType": "INTEGER"
}
]
}
,
{
"name": "COURSE",
"description": "Course details",
"columns": [
{
"name": "NAME",
"columnType": "TEXT"
}
,
{
"name": "COURSENUMBER",
"columnType": "INTEGER"
}
,
{
"name": "DESCRIPTION",
"columnType": "TEXT"
}
,
{
"name": "POINTS",
"columnType": "INTEGER"
}
]
}
]
}
3. Right click on the file -> 'Generate SQLite Model...' 
4. Refresh the project
Generated Code
Entities
Each table is converted to Java entity and is generated under 'entities' package
| - entities Actions
Each entity can be creates, updated, deleted or retrieved from the database. The support for CRUD actions is located under 'actions' package
| - actions
| - create
| - delete
| - read
| - update Model
The entry point for all operations above SQLite database are done via Model.java class, which is located under 'model' package
| - model Usage
Create
For each defined table in the JSON file you can create a new entity which will be saved in the SQLite table
Student student = new Student();
student.setFirstname("John");
student.setLastname("Smith");
student.setAge(30);
Model model = Model.getInstance(context);
model.createStudent(student);
Retrieve
For each defined table in the JSON file you can retrieve all entities from that SQLite table
Model model = Model.getInstance(context);
List<Student> students = model.readStudent();
Update
For each defined table in the JSON file you can update existing entity from the SQLite table
student.setAge(31);
Model model = Model.getInstance(context);
model.updateStudent(student);
Delete
For each defined table in the JSON file you can delete existing entity from the SQLite table
Model model = Model.getInstance(context);
model.deleteStudent(student);
How it works
- The first time the singleton instance of the model is created
Model model = Model.getInstance(context), all the SQLite database content is loaded into the memory. - Each of CRUD commands works directly with the cached data and SQLite database. For example,
model.update...(Object object)will update the entity in the memory and then update the raw in the database. Thus, the database is always synced.
