Question

拜托，你能帮我做回滚动作吗？这是一种魔术 - liquibase向我报告成功的回滚动作，但没有任何改变。我们使用sql格式的SQL。例如，我有3个文件：

CASE-0-1.sql：

--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));

CASE-0-2.sql：

--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));

CASE-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，我在TAG数据库中添加：

/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"

之后，我会在每个文件应用后应用文件和TAG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

看起来很好，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 - 我们拥有相同的表集，没有表丢失，也没有创建其他表。

我们在回滚日志文件中有什么：

我检查了不同的变种，不同的liquibase文件格式，不同的命令行选项 - 没用。 Liquibase总是说＆＃34; Liquibase回滚成功＆＃34;，但什么都不做。

请帮忙。可能有人使用sql或其他格式的回滚操作？哪里出错？我做错了什么？是否正在使用liquibase功能？

Answer 1

希望您仍然对帮助感兴趣，但据我所知，您不包括CASE-0-3 SQL脚本，因此liquibase不了解CASE-0以外的更改你提供的-2标签 - 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脚本作为更改日志文件。

如果有帮助，请告诉我！

Answer 2

我解决了该问题，并发现它可以工作。问题如下：在迁移/更新期间，--changeLogFile参数获取文件名，并在--classpath文件夹中找到它。然后，它将具有完整路径的文件名存储在其日志表中。

但是，在回滚时，它不起作用。您需要在--changeLogFile中提供文件名的完整路径。它只是将此参数与日志表进行比较。在这种情况下，在对其日志表进行搜索之前，它不使用classpath预先添加到changeLogFile。

Liquibase回滚不能与＆＃34; Liquibase回滚成功＆＃34;
