您可以只清除给定文件的 liquibase 校验和吗？

Question

运行

liquibase --url=jdbc:oracle:thin:@localhost:1521/XE --    
driver=oracle.jdbc.OracleDriver --changeLogFile=db.changelog-next.xml --    
username=owner --password=xxxx --logLevel=info clearCheckSums

清除数据库中的所有校验和。有没有办法只清除 db.changelog-next.xml.

中变更集的校验和

谢谢

Answer 1

我认为 clearCheckSums 没有其他命令或参数可以执行此操作。

但您可以手动执行此操作。 clearCheckSums 所做的只是使 databasechangelog table 的 MD5SUM 列无效。

所以是这样的：

update databasechangelog set md5sum=null where filename like '%db.changelog-next.xml';

应该可以。

（我还没有测试这个 SQL。这只是一个例子 - 所以在你将它应用到你的生产数据库之前确保它适用于开发数据库。）

如果您使用的是 Liquibase 的 Maven 插件，您的 pom.xml 文件中可能会有这样的内容，您在其中使用 clearCheckSum 作为每次执行的参数（您可能想像我一样拆分文件在这里做的）：

        <build>
            <plugins>
                <plugin>
                    <!--NOTE: clearCheckSums=true attribute will make the changesets run only once.
                        The runOnChange attribute added to changesets will not work as originally intended.-->

您始终可以使用 Maven 的参数化构建，将默认值添加为：

<properties>   
    <liquibase.clearCheckSums>true</liquibase.clearCheckSums>   
    <database.username>userSchema</database.username>   
    <database.password>myUserPassword</database.password>   
    <database.adminschema.username>adminSchema</database.adminschema.username> 
    <database.adminschema.password>myAdminPassword</database.adminschema.password> 
    <database.liquibasecontext>!IntegrationTesting</database.liquibasecontext> 
</properties>

您可以只清除给定文件的 liquibase 校验和吗？
