Postgres - 字符变化=整数

Question

我尝试将dbite从SQLite更改为PostgreSQL。一些查询返回“字符变化=整数”。

OrmLite实体（订阅实体）：

@DatabaseTable(tableName = "subscription")
public class Subscription {
    public static final String SUBSCRIPTION_ID = "id";
    @DatabaseField(generatedId = true, columnName = SUBSCRIPTION_ID)
    private int subscriptionId;

    public static final String BUYER = "buyer";
    @DatabaseField(foreign = true, columnName = BUYER)
    private BuyerUser buyer;

    public static final String SHOP = "shop";
    @DatabaseField(foreign = true, columnName = SHOP)
    private Shop shop;
}

商店实体：

@DatabaseTable(tableName = "shop")
public class Shop {
    public static final String SHOP_ID_FIELD = "id";
    @DatabaseField(generatedId = true, allowGeneratedIdInsert = true, columnName = SHOP_ID_FIELD)
    private int shopId;

    public static final String SHOP_NAME_FIELD = "shop_name";
    @DatabaseField(columnName = SHOP_NAME_FIELD)
    private String shop_name;
}

商店ID类型为int，但在pgAdmin：

CREATE TABLE subscription
(
    id serial NOT NULL,
    buyer character varying(255),
    shop character varying(255),
    CONSTRAINT subscription_pkey PRIMARY KEY (id)
)

商店外国字段类型是char。怎么了？

Answer 1

这是我的错。字段类型真的是char。
