MYSQL 操作

1. MYSQL 执行脚本

1.1 在 jpaas\jpaas\metadata\scripts\6.0\mysql 路径下，有数据库脚本

Tips：平台功能不断的在进行创新，数据库脚本也会更新，如有缺失的字段或表请及时联系部署人员获取最新脚本！

1.2 连接工具执行数据库脚本，记住数据库账号密码噢！

1.3 版本已经升级，数据库更新

1.3.1 所有库的undo_log都需要升级至最新官方脚本

1.3.1.1 MySQL数据库的undo_log表

-- for AT mode you must to init this sql for you business database. the seata server not need it.
CREATE TABLE IF NOT EXISTS `undo_log`
(
    `branch_id`     BIGINT(20)   NOT NULL COMMENT 'branch transaction id',
    `xid`           VARCHAR(100) NOT NULL COMMENT 'global transaction id',
    `context_`       VARCHAR(128) NOT NULL COMMENT 'undo_log context,such as serialization',
    `rollback_info` LONGBLOB     NOT NULL COMMENT 'rollback info',
    `log_status`    INT(11)      NOT NULL COMMENT '0:normal status,1:defense status',
    `log_created`   DATETIME(6)  NOT NULL COMMENT 'create datetime',
    `log_modified`  DATETIME(6)  NOT NULL COMMENT 'modify datetime',
    UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 1
  DEFAULT CHARSET = utf8 COMMENT ='AT transaction mode undo table';

1.3.1.2 Oracle数据库的undo_log表

-- for AT mode you must to init this sql for you business database. the seata server not need it.
CREATE TABLE undo_log
(
    id            NUMBER(19)    NOT NULL,
    branch_id     NUMBER(19)    NOT NULL,
    xid           VARCHAR2(100) NOT NULL,
    context_       VARCHAR2(128) NOT NULL,
    rollback_info BLOB          NOT NULL,
    log_status    NUMBER(10)    NOT NULL,
    log_created   TIMESTAMP(0)  NOT NULL,
    log_modified  TIMESTAMP(0)  NOT NULL,
    PRIMARY KEY (id),
    CONSTRAINT ux_undo_log UNIQUE (xid, branch_id)
);

COMMENT ON TABLE undo_log IS 'AT transaction mode undo table';

-- Generate ID using sequence and trigger
CREATE SEQUENCE UNDO_LOG_SEQ START WITH 1 INCREMENT BY 1;

1.3.2 seata使用最新官方脚本
