-- =============================================

-- 1. 项目表
CREATE TABLE IF NOT EXISTS system_project (
    id              BIGINT PRIMARY KEY AUTO_INCREMENT COMMENT '项目编号',
    tenant_id       BIGINT NOT NULL COMMENT '所属租户编号',
    name            VARCHAR(100) NOT NULL COMMENT '项目名称',
    code            VARCHAR(50) NOT NULL COMMENT '项目编码（如楼盘编号）',
    status          TINYINT DEFAULT 0 COMMENT '状态（0=正常, 1=禁用）',
    contact_name    VARCHAR(30) COMMENT '项目联系人',
    contact_mobile  VARCHAR(30) COMMENT '联系手机',
    address         VARCHAR(500) COMMENT '项目地址',
    remark          VARCHAR(500) COMMENT '备注',
    creator         VARCHAR(64) DEFAULT '' COMMENT '创建者',
    create_time     DATETIME DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
    updater         VARCHAR(64) DEFAULT '' COMMENT '更新者',
    update_time     DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
    deleted         BIT DEFAULT 0 COMMENT '是否删除',
    UNIQUE KEY uk_tenant_code (tenant_id, code, deleted),
    INDEX idx_tenant (tenant_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='项目表';

-- 2. 用户-项目关联表
CREATE TABLE IF NOT EXISTS system_user_project (
    id          BIGINT PRIMARY KEY AUTO_INCREMENT COMMENT '编号',
    user_id     BIGINT NOT NULL COMMENT '用户编号',
    project_id  BIGINT NOT NULL COMMENT '项目编号',
    tenant_id   BIGINT NOT NULL COMMENT '租户编号',
    creator     VARCHAR(64) DEFAULT '' COMMENT '创建者',
    create_time DATETIME DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
    updater     VARCHAR(64) DEFAULT '' COMMENT '更新者',
    update_time DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
    deleted     BIT DEFAULT 0 COMMENT '是否删除',
    UNIQUE KEY uk_user_project (user_id, project_id, deleted),
    INDEX idx_project (project_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户-项目关联表';
