MyBatis迁移:迁移原因org.apache.ibatis.jdbc.RuntimeSqlException

Dan*_*Qiu 1 mysql mybatis

我刚刚安装了Mybatis Migration并按照他们的说明操作.init,new,status命令有效,但"向上迁移"会导致以下错误:

两个mysql DDL(create table和alter table)是通过文件20140410190604_create_changelog.sql中的迁移生成的.但是,如果我手动运行sql它没有抱怨任何语法错误.

什么可能导致这种"迁移"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);

send_full_script=falseenviornment.properties文件中设置可以解决问题.
