SQLite Model Generator

Eclipse plugin - Generate SQLite model for Android based on JSON schema file

Usage of the plugin

1. Install the plugin

Update site: http://romkuapps.com/Apps/SQLite/update

2. Create JSON file that describes your sqlite schema.

  • Schema has name and tables
  • table has name, description and columns
  • column has name and columnType
  • columnType can be TEXT or INTEGER only

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.
