With ormLite I can get all record with :
myDao.queryForAll();
How can I get only the first 10 records and not all records ?
You will have to use QueryBuilder and set the limit. Here's the javadoc reference: http://ormlite.com/javadoc/ormlite-core/com/j256/ormlite/stmt/QueryBuilder.html#limit%28java.lang.Long%29
This is give or take what the code will look like:
QueryBuilder<MyDataObject, String> builder = myDao.queryBuilder();
builder.limit(10);
builder.orderBy("columnName", true) // true for ascending, false for descending
List<MyDataObject> list = myDao.query(builder.prepare()); // returns list of ten items
