Question

There is plenty answers and tutorials using InsertHelper to do fast bulk insert in SQLiteDatabase.
But InsertHelper is deprecated as of API 17.

What is now the fastest method to bulk insert large sets of data in Android SQLite ?

So far my greatest concern is that SQLiteStatement is not very comfortable to work with, where InsertHelper had binding columns and binding values, which was kind of trivial.

Answer 1

SQLiteStatement has also binding methods, it extends SQLiteProgram.

Just run it in transaction:

    final SQLiteDatabase db = mOpenHelper.getWritableDatabase();
    final SQLiteStatement statement = db.compileStatement(INSERT_QUERY);
    db.beginTransaction();
    try {
        for(MyBean bean : list){
            statement.clearBindings();
            statement.bindString(1, bean.getName());
            // rest of bindings
            statement.execute(); //or executeInsert() if id is needed
        }
        db.setTransactionSuccessful();
    } finally {
        db.endTransaction();
    }

EDIT

I can’t find nice solution in SQLiteQueryBuilder but it’s as simple as:

final static String INSERT_QUERY = createInsert(DbSchema.TABLE_NAME, new String[]{DbSchema.NAME, DbSchema.TITLE, DbSchema.PHONE});

static public String createInsert(final String tableName, final String[] columnNames) {
    if (tableName == null || columnNames == null || columnNames.length == 0) {
        throw new IllegalArgumentException();
    }
    final StringBuilder s = new StringBuilder();
    s.append("INSERT INTO ").append(tableName).append(" (");
    for (String column : columnNames) {
        s.append(column).append(" ,");
    }
    int length = s.length();
    s.delete(length - 2, length);
    s.append(") VALUES( ");
    for (int i = 0; i < columnNames.length; i++) {
        s.append(" ? ,");
    }
    length = s.length();
    s.delete(length - 2, length);
    s.append(")");
    return s.toString();
}
