在隨後的更新中，liquibase變更集排序更改是否更改？

Question

liqibase中的CHANGESET執行依賴於它在xml中的位置嗎？例如，如果我有一個在liquibase腳本如下

<changeSet id="20140211_001" author="test"> 
    <createTable tableName="alarm_notification_archive"> 
     <column name="id" type="bigint"> 
      <constraints nullable="false" /> 
     </column> 

     <column name="event_timestamp" type="timestamp" defaultValue="0000-00-00 00:00:00"> 
      <constraints nullable="false" /> 
     </column> 
    </createTable> 
</changeSet> 

<changeSet id="20140210_001" author="test"> 
    <sql>ALTER TABLE `notification_archive` ADD COLUMN 
     `is_Alarm_Outstanding` BOOLEAN DEFAULT FALSE</sql> 
    <rollback> 
     <sql>ALTER TABLE notification_archive DROP COLUMN 
      is_Alarm_Outstanding 
       </sql> 
    </rollback> 
</changeSet> 

我的理解是變更排序是 1）20140211_001 2）20140210_001

如果我現在在添加其他變更1和2之間

<changeSet id="20140211_001" author="test"> 
    <createTable tableName="alarm_notification_archive"> 
     <column name="id" type="bigint"> 
      <constraints nullable="false" /> 
     </column> 

     <column name="event_timestamp" type="timestamp" defaultValue="0000-00-00 00:00:00"> 
      <constraints nullable="false" /> 
     </column> 
    </createTable> 
</changeSet> 

<changeSet id="20140212_001" author="test"> 
    <sql>ALTER TABLE `notification_archive` ADD COLUMN 
     `is_Alarm_Outstanding` BOOLEAN DEFAULT FALSE</sql> 
    <rollback> 
     <sql>ALTER TABLE alarm_notification_archive DROP COLUMN 
      is_Alarm_Outstanding 
      </sql> 
    </rollback> 
</changeSet> 

<changeSet id="20140210_001" author="test"> 
    <sql>ALTER TABLE `notification_archive` ADD COLUMN 
     `is_Alarm_Outstanding` BOOLEAN DEFAULT FALSE</sql> 
    <rollback> 
     <sql>ALTER TABLE alarm_notification_archive DROP COLUMN 
      is_Alarm_Outstanding 
      </sql> 
    </rollback> 
</changeSet> 

將新變更的執行順序是 1）20140211_001 2）20140212_001 3）20140210_001

Answer 1

是的，Liquibase按順序讀取changeSets。見Changeset Documentation
