-以下是使用小驼峰命名并用双引号包裹字段名的PostgreSQL建表语句和测试数据插入语句：
|
|
|
-
|
|
|
-### 1. 建表语句
|
|
|
-
|
|
|
-```sql

|
|
|
- "updatedAt" TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
|
|
|
-);
|
|
|
-
|
|
|
--- 生长记录表
|
|
|
-CREATE TABLE "GrowthRecord" (
|
|
|
- "objectId" VARCHAR(36) PRIMARY KEY,
|
|
|
- "recordType" VARCHAR(20) CHECK ("recordType" IN ('文字记录', '图片记录')),

--- 图片存储关联表
|
|
|
-CREATE TABLE "GrowthRecordImages" (

|
|
|
-);
|
|
|
-```
|
|
|
-
|
|
|
-### 2. 测试数据插入语句
|
|
|
-
|
|
|
-```sql
|
|
|
--- 插入测试用户
|
|
|
-INSERT INTO "User" ("objectId", "username", "email", "mobilePhone") VALUES
|
|
|
-('usr001', 'farmer_wang', 'wang@example.com', '13800138001'),
|
|
|
-('usr002', 'farmer_li', 'li@example.com', '13900139001');
|
|
|
-
|
|
|
--- 插入测试农田
|
|
|
-INSERT INTO "Farmland" ("objectId", "farmlandName", "area", "cropType", "latitude", "longitude", "ownerId", "status", "irrigationSystem") VALUES
|
|
|
-('fld001', '王家的麦田', 5.2, '小麦', 39.9042, 116.4074, 'usr001', '生长期', '滴灌系统'),
|
|
|
-('fld002', '李家的玉米地', 8.5, '玉米', 34.3416, 108.9398, 'usr002', '播种期', '喷灌系统');
|
|
|
-
|
|
|
--- 插入农事提醒
|
|
|
-INSERT INTO "FarmingReminder" ("objectId", "reminderType", "content", "dueDate", "isCompleted", "farmlandId", "priority") VALUES
|
|
|
-('rem001', '灌溉', '麦田需要浇水', CURRENT_TIMESTAMP + INTERVAL '2 days', false, 'fld001', 1),
|
|
|
-('rem002', '施肥', '玉米地需要追肥', CURRENT_TIMESTAMP + INTERVAL '5 days', false, 'fld002', 2);
|
|
|
-
|
|
|
--- 插入生长记录
|
|
|
-INSERT INTO "GrowthRecord" ("objectId", "recordType", "description", "recordDate", "growthStage", "temperature", "humidity", "farmlandId") VALUES
|
|
|
-('rec001', '文字记录', '小麦抽穗期开始', CURRENT_TIMESTAMP - INTERVAL '3 days', '抽穗期', 22.5, 65.0, 'fld001'),
|
|
|
-('rec002', '图片记录', '玉米幼苗生长情况', CURRENT_TIMESTAMP - INTERVAL '1 day', '幼苗期', 25.0, 70.0, 'fld002');
|
|
|
-
|
|
|
--- 插入生长记录图片
|
|
|
-INSERT INTO "GrowthRecordImages" ("recordId", "fileUrl") VALUES
|
|
|
-('rec002', 'https://example.com/images/corn_seedling_1.jpg'),
|
|
|
-('rec002', 'https://example.com/images/corn_seedling_2.jpg');
|
|
|
-```
|
|
|
-
|
|
|
-### 修改说明：
|
|
|
-
|
|
|
-1. **命名规范**：
|
|
|
- - 所有字段名使用小驼峰命名并用双引号包裹
|
|
|
- - 表名使用大驼峰命名并用双引号包裹
|
|
|
- - 保留Parse Server原始字段名（如objectId/createdAt/updatedAt）
|
|
|
-
|
|
|
-2. **修正问题**：
|
|
|
- - 修正了农事提醒表中的字段名拼写错误（reminderType）
|
|
|
- - 确保所有引用字段名都使用小驼峰格式
|
|
|
-
|
|
|
-3. **兼容性**：
|
|
|
- - 完全兼容PostgreSQL的标识符引用规则
|
|
|
- - 保留所有原始设计的约束和关系
|
|
|
-
|
|
|
-4. **测试数据**：
|
|
|
- - 保持与之前相同的测试场景
|
|
|
- - 所有字段引用都使用新的命名格式
|
|
|
-
|
|
|
-这种格式可以直接在PostgreSQL中执行，且与Parse Server的命名规范完全一致。如需在其它数据库中使用，可能需要根据数据库特性调整引号的使用方式。
