列名重复，在 liquibase 中评论变更集并取消评论后

Question

在我的 Java 本地开发环境中，我错误地注释了一些变更集并运行了应用程序。 现在，当我取消注释更改集时，Liquibase 崩溃并抱怨数据库中的重复列。

有什么方法可以清除 Liquibase 而不必删除整个数据库？ 好像有校验和冲突什么的。

Answer 1

看起来不像是校验和冲突。看起来其他 changeSet 已经添加了此列。

但是，如果您想删除有关已执行 changeSet 的记录，请按照以下步骤操作（尽管这样做不是一个好习惯，但评论 changeSets 也不是）：

在ID 列的databasechangelog 表中找到您需要的changeSet 的ID 并删除此行。

如果没有这个记录，liquibase 将不会知道这个 changeSet 曾经被执行过，并且会在下一次应用程序启动时尝试执行它。

我建议您尝试将<preConditions> 添加到changeSets 以避免此类错误。在这种情况下，它可能如下所示：

<preConditions onFail="MARK_RUN">
    <not>
        <columnExists tableName="api_user" columnName="option_cgu"/>
    </not>
</preConditions>
