Mysql MyBatis迁移：向上迁移导致org.apache.ibatis.jdbc.RuntimeSqlException

我只是安装和遵循他们的。init、new和status命令工作正常，但“向上迁移”会导致以下错误：

两个mysql DDL（create table和alter table）是通过迁移在文件20140410190604_create_changelog.sql中生成的。但是，如果我手动运行sql，它不会抱怨任何语法错误

什么可能导致这种“向上迁移”问题

---

在

environment.properties

文件中设置

send\u full\u script=false

可以解决问题。

可以解决问题

The script is like:

CREATE TABLE CHANGELOG (
ID NUMERIC(20,0) NOT NULL,
APPLIED_AT VARCHAR(25) NOT NULL,
DESCRIPTION VARCHAR(255) NOT NULL
);

ALTER TABLE CHANGELOG
ADD CONSTRAINT PK_CHANGELOG
PRIMARY KEY (id);
