Как я могу регистрировать запросы SQLite запросов в Android?

Я использую код, как показано ниже. Есть ли какие-нибудь способы увидеть или записать это для нас? когда этот запрос был запущен. Например, я хочу записать все запросы INSERT, UPDATE, DELETE, чтобы сохранить их в другой таблице.

Я нашел много других ответов, но я все еще не могу решить эту проблему.

Вот код, например, для получения запроса журнала на INSERT: 

// --- add addProductServiceCategory ---//
public long addProductServiceCategory(ProductServiceCategory productServiceCategory){
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put(ProductServiceCategoryColumn.Entry.ID, productServiceCategory.id);
    values.put(ProductServiceCategoryColumn.Entry.PROJECT_ID, productServiceCategory.project_id);
    values.put(ProductServiceCategoryColumn.Entry.TITLE, productServiceCategory.title);
    values.put(ProductServiceCategoryColumn.Entry.CREATE_AT, productServiceCategory.created_at);
    values.put(ProductServiceCategoryColumn.Entry.UPDATE_AT, productServiceCategory.updated_at);

    long todo_id = db.insert(ProductServiceCategoryColumn.Entry.TABLE_PRODUCT_SERVICE_CATEGORY, null, values);
    return todo_id;
}

Пример: У меня есть имя таблицы tbl_log_queries. И в этой таблице я хочу хранить зарегистрированные запросы.

Вот мои tbl_log_queries

Если ваша конечная цель - вставить строки в другую таблицу, когда строка вставлена ​​/ обновлена ​​/ удалена, то ответом может быть TRIGGER.

Примите во внимание следующее: - 

DROP TABLE IF EXISTS product_service_category;
DROP TABLE IF EXISTS product_action_log;
DROP TRIGGER IF EXISTS product_service_category_inserted;
DROP TRIGGER IF EXISTS product_service_category_updated;
DROP TRIGGER IF EXISTS product_service_category_deleted;

-- The Main/Original Table
CREATE TABLE IF NOT EXISTS product_service_category 
    (
        _id INTEGER PRIMARY KEY, 
        product_id INTEGER, 
        title TEXT, 
        created_at TEXT DEFAULT CURRENT_TIMESTAMP, 
        updated_at TEXT DEFAULT 0
        )
    ;
-- The Logging table (aka Your Other Table)
CREATE TABLE product_action_log 
    (
        _id INTEGER PRIMARY KEY, 
        product_service_category_reference INTEGER, 
        timestamp TEXT DEFAULT CURRENT_TIMESTAMP, 
        action_taken TEXT
    )
;

-- Trigger for logging INSERTS
CREATE TRIGGER IF NOT EXISTS product_service_category_inserted AFTER INSERT ON product_service_category
    BEGIN 
        INSERT INTO product_action_log (product_service_category_reference, action_taken) VALUES(new._id,'INSERTED');
    END;

    -- Trigger for logging UPDATES
CREATE TRIGGER IF NOT EXISTS product_service_category_updated AFTER UPDATE ON product_service_category
    BEGIN 
        INSERT INTO product_action_log (product_service_category_reference, action_taken) VALUES(new._id,'UPDATED');
    END;

-- Trigger for loggin Deletes
CREATE TRIGGER IF NOT EXISTS product_service_category_deleted AFTER DELETE ON product_service_category
    BEGIN INSERT INTO product_action_log (product_service_category_reference, action_taken) VALUES(old._id,'DELETED');
        END;

-- Add some testing data (4 rows into the main table)
INSERT INTO product_service_category (product_id, title) 
    VALUES
        (1,'Title 1'),(2,'Title 2'),(3,'Title 3'),(4,'and so on')
;

-- Show what the log table looks like (reference data from the main table )
SELECT * FROM product_action_log
    JOIN product_service_category ON product_service_category_reference = product_service_category._ID
;

-- Update some data 
UPDATE product_service_category SET title = 'changed', updated_at = datetime('now') WHERE _id = 2;
UPDATE product_service_category SET title = 'changed', updated_at = datetime('now') WHERE _id = 4;

-- Show what the log looks like after the updates
SELECT * FROM product_action_log
    JOIN product_service_category ON product_service_category_reference = product_service_category._ID;

-- delete a row from the main table 
DELETE FROM product_service_category WHERE _id = 1;

-- Show what the data in the log looks like now (note LEFT JOIN)
SELECT * FROM product_action_log
    LEFT JOIN product_service_category ON product_service_category_reference = product_service_category._ID;

Первый запрос приводит к: -

Второй запрос после некоторых обновлений приводит к: -

Третий запрос после удаления приводит к: -

  • Обратите внимание, чтоLEFT JOIN включает строки, которые ссылаются на удаленную категорию product_service_category (поскольку она была удалена, ссылка на нее равна нулю).

Единственное дополнительное необходимое кодирование - это создание TRIGGERS, а затем любые запросы и т. Д.которые обрабатывают зарегистрированные данные (которые были бы на картах в любом случае).

Применимо к Android

Использование триггеров может быть реализовано следующим образом (это с учетом данных, которые вы хотитечтобы записать, хотя и не используемый SQL крысей данные, которые затем могут быть использованы для построения SQL).

Первый базовый эквивалент productServiceCategory.java 

public class productServiceCategory {

    public long id;
    public long project_id;
    public String title;
    public String created_at;
    public String updated_at;


    public productServiceCategory(long id, long project_id, String title, String created_at, String updated_at) {
        this.id = id;
        this.project_id = project_id;
        this.title = title;
        this.created_at = created_at;
        this.updated_at = updated_at;
    }
}

Второй расширенный эквивалент ProductServiceCategoryColumn.java с большинством изменений для триггеров и таблицы журнала, таблица содержит столбцы для старых и новых значений: - 

public class ProductServiceCategoryColumn {

    public class Entry {
        public static final String TABLE_PRODUCT_SERVICE_CATEGORY = "product_service_category";
        public static final String ID = BaseColumns._ID;
        public static final String PROJECT_ID = "project_id";
        public static final String TITLE = "title";
        public static final String CREATE_AT = "create_at";
        public static final String UPDATE_AT = "update_at";
        public static final String CREATETABLE = "CREATE TABLE IF NOT EXISTS " + TABLE_PRODUCT_SERVICE_CATEGORY +
                "(" +
                ID + " INTEGER PRIMARY KEY," +
                PROJECT_ID + " INTEGER," +
                TITLE + " TEXT," +
                CREATE_AT + " TEXT DEFAULT CURRENT_TIMESTAMP," +
                UPDATE_AT + " TEXT DEFAULT NULL" +
                ")";
    }

    public class Log {

        public static final String TABLE_LOG_QUERIES = "tbl_log";
        public static final String ID = BaseColumns._ID;

        public static final String NEW_TITLE = "new_" + Entry.TITLE;
        public static final String OLD_CREATE_AT = "old_" + Entry.CREATE_AT;
        public static final String NEW_CREATE_AT = "new_" + Entry.CREATE_AT;
        public static final String OLD_UPDATE_AT = "old_" + Entry.UPDATE_AT;
        public static final String NEW_UPDATE_AT = "new_" + Entry.UPDATE_AT;
        public static final String CREATETABLE = "CREATE TABLE IF NOT EXISTS " + TABLE_LOG_QUERIES +
                "(" +

                OLD_TITLE + " TEXT," +
                NEW_TITLE + " TEXT," +
                OLD_CREATE_AT + " TEXT," +
                NEW_CREATE_AT + " TEXT, " +
                OLD_UPDATE_AT + " TEXT," +
                NEW_UPDATE_AT + " TEXT" +

третий помощник базы данных DBHelper.java 

public class DBHelper extends SQLiteOpenHelper {

Последний вызов операций вставки, обновления и удаления (предназначен для однократного выполнения) из onCreate действия: - 

public class MainActivity extends AppCompatActivity {

    DBHelper mDBHlpr;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        mDBHlpr.addProductServiceCategory(new productServiceCategory(1,1,"Title1","2018-01-01 10:30", ""));
        mDBHlpr.addProductServiceCategory(new productServiceCategory(2,2,"hello title","2018-02-28",""));

        mDBHlpr.addProductServiceCategory(new productServiceCategory(4,1,"A N Other","2017-11-10",""));

        mDBHlpr.updateProductServiceCategory(1,new productServiceCategory(1,2,"Changed Title","2018-01-01 10:30","2018-10-16 19:52"));
        mDBHlpr.deleteProductServiceCategory(3);

        Cursor csr = mDBHlpr.getWritableDatabase().query(ProductServiceCategoryColumn.Log.TABLE_LOG_QUERIES,null,null,null,null,null,null);
        DatabaseUtils.dumpCursor(csr);
