Question

我刚刚安装了Mybatis Migration并关注了instructions。 init，new，status命令工作但是＆＃34;向上迁移＆＃34;导致以下错误：

------------------------------------------------------------------------
-- MyBatis Migrations - up

========== Applying: 20140410190604_create_changelog.sql =======================
Error executing: --  Create Changelog

-- Default DDL for changelog table that will keep
-- a record of the migrations that have been run.

-- You can modify this to suit your database before
-- running your first migration.

-- Be sure that ID and DESCRIPTION fields exist in
-- BigInteger and String compatible fields respectively.

CREATE TABLE CHANGELOG (

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，它不会抱怨任何语法错误。

可能导致此问题＆＃34;向上迁移＆＃34;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);

Answer 1

在send_full_script=false文件中设置enviornment.properties可解决问题。
