不使用"Liquibase回滚成功“的Liquibase回滚

Question

拜托，你能帮我做回滚动作吗？这是一种神奇的-清算基础报告我成功的回滚行动，但什么都没有改变。我们使用SQL格式的sql。例如，我有3个文件：

案例-0-1 CASE：

--liquibase formatted sql

--changeset CASE-0-1:1 failOnError:true
CREATE TABLE tt1(
cc1 INT(11));

--rollback DROP TABLE tt1;
--rollback CREATE TABLE tr1(
--rollback cr1 INT(20));

案例-0-2 CASE：

--liquibase formatted sql

--changeset CASE-0-2:1 failOnError:true
CREATE TABLE tt2(
cc2 INT(11));

--rollback DROP TABLE tt2;
--rollback CREATE TABLE tr2(
--rollback cr2 INT(20));

案例-0-3.sql：

--liquibase formatted sql

--changeset CASE-0-3:1 failOnError:true
CREATE TABLE tt3(
cc3 INT(11));

--rollback DROP TABLE tt3;
--rollback CREATE TABLE tr3(
--rollback cr3 INT(20));

在进行任何更改之前，我会标记数据库：

/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --logFile=0state.tag.log --username=trunk --password=Trunk \
  tag "0state"

在此之后，我在每个文件应用之后应用文件和标记数据库：

/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --changeLogFile=CASE-0-1.sql --logFile=CASE-0-1.sql.update.log --username=trunk --password=Trunk \
  update
/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --logFile=CASE-0-1.sql.tag.log --username=trunk --password=Trunk \
  tag "CASE-0-1"

/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --changeLogFile=CASE-0-2.sql --logFile=CASE-0-2.sql.update.log --username=trunk --password=Trunk \
  update
/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --logFile=CASE-0-2.sql.tag.log --username=trunk --password=Trunk \
  tag "CASE-0-2"

/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --changeLogFile=CASE-0-3.sql --logFile=CASE-0-3.sql.update.log --username=trunk --password=Trunk \
  update
/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --logFile=CASE-0-3.sql.tag.log --username=trunk --password=Trunk \
  tag "CASE-0-3"

结果：

[root@mysql]# mysql -e "SELECT ID, AUTHOR, FILENAME, DATEEXECUTED, ORDEREXECUTED, EXECTYPE, DESCRIPTION, COMMENTS, TAG \
>           FROM DATABASECHANGELOG;" liquibase_test
+---------------+-----------+--------------------+---------------------+---------------+----------+-------------+----------+----------+

| tt3                      |
+--------------------------+

现在，让我们尝试回滚：

/root/liquibase/liquibase --logLevel=debug --classpath=/usr/share/java/mysql-connector-java.jar --driver=com.mysql.jdbc.Driver \
  --url="jdbc:mysql://localhost/liquibase_test?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true" \
  --changeLogFile=CASE-0-2.sql --logFile=CASE-0-2.sql.rollback.log --username=trunk --password=Trunk \
  rollback "CASE-0-2"
Liquibase Rollback Successful

看起来一切正常，但没有执行回滚：

[root@mysql]# mysql -e "SELECT ID, AUTHOR, FILENAME, DATEEXECUTED, ORDEREXECUTED, EXECTYPE, DESCRIPTION, COMMENTS, TAG \
>           FROM DATABASECHANGELOG;" liquibase_test

正如您所看到的--我们拥有的同一组表，没有表被删除，也没有创建额外的表。

我们在回滚日志文件中拥有的内容：

我检查了不同的变体，不同的清算文件格式，不同的命令行选项-无用。Liquibase总是说"Liquibase回滚成功“，但什么也不做。

拜托救救我。可能有人在使用sql或其他格式时使用回滚操作？哪里出错了？我做错什么了？它有工作液基功能吗？

Answer 1

希望您仍然对帮助感兴趣，但据我所知，您没有包括您的CASE-0-3 SQL脚本，因此清算库不知道您提供的CASE-0-2标记之外的更改--因此它无法回滚。

我的团队所做的是创建一个更健壮的changelog.xml，它引用我们的.sql脚本，而不是使用.sql脚本作为变更文件。

如果这有帮助的话请告诉我！

Answer 2

我解决了这个问题，发现它奏效了。问题如下:在迁移/更新过程中，--changeLogFile参数获取文件名，并在--类路径文件夹中找到它。然后，它在其日志表中存储具有完整路径的文件名。

但是，在回滚时，同样的方法不起作用。您需要在--changeLogFile中提供文件名的完整路径。它只是将这个参数与日志表进行比较。在本例中，它不使用类路径在其日志表中进行搜索之前为changeLogFile做准备。
