在Android SQLite db中如何匹配数据库的多个表中具有相同id的特定列值？

Question

我从Json数据中将数据转储到SQLite中.现在我的问题是我有一个包含多个表的数据库我希望使用id来关联多个表.这些是我创建的3个表.

这是我们有产品清单的第一张表,

private static final String DATABASE_CREATE_PRODUCT =
            "CREATE TABLE if not exists " + "product_template" + " (" +
                    "_id" + " integer PRIMARY KEY autoincrement," +
                    "name" + "," +
                    "list_price" + "," +
                    "create_date" + "," +
                    "default_code" + "," +
                    "ean13" + "," +
                    "image_new" + "," +
                    "image_variant" +
                    ");";

这是我们有合作伙伴名单的第二张表,

    private static final String DATABASE_CREATE_PARTNER =
            "CREATE TABLE if not exists " + "res_partner" + " (" +
                    "_id" + " integer PRIMARY KEY autoincrement," +
                    "phone" + "," +
                    "mobile" + "," +
                    "name" +
                    ");";

这是我们有账户线的第三张表,

    private static final String DATABASE_CREATE_LINE =
            "CREATE TABLE if not exists " + "account_invoice_line" + " (" +
                    "product_id" + "," +
                    "partner_id" +
                    ");";

在第三个表中,我有两列product_id和partner_id,我应该匹配partner_id与第二个表列_id的值,我应该在其中获取name列的值,并通过列partner_id中的值我应该与第一个表 _id 匹配,我应该得到值在名称列中.

任何人都可以帮助创建这些表之间的关系吗？

尝试这样的事情：

SELECT t1.name prod_name, t2.name part_name from product_template t1, res_partner t2, account_invoice_line t3 where t3.product_id = t1.id and t3.partner_id = t2.id
