mysql - Liquibase 回滚不适用于 "Liquibase Rollback Successful"

标签 mysql liquibase

请问您能帮我进行回滚操作吗？这是某种魔法 - liquibase 向我报告成功的回滚操作，但没有任何变化。 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"

之后，我在每个文件应用后应用文件和标签数据库:

/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
+---------------+-----------+--------------------+---------------------+---------------+----------+-------------+----------+----------+
| ID            | AUTHOR    | FILENAME           | DATEEXECUTED        | ORDEREXECUTED | EXECTYPE | DESCRIPTION | COMMENTS | TAG      |

+---------------+-----------+--------------------+---------------------+---------------+----------+-------------+----------+----------+

| 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，但回滚没有执行:

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

| 1             | CASE-0-3  | CASE-0-3.sql       | 2017-09-27 10:42:12 |             4 | EXECUTED | sql         |          | CASE-0-3 |
+---------------+-----------+--------------------+---------------------+---------------+----------+-------------+----------+----------+

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

正如您所看到的 - 我们拥有同一组表，没有删除表，也没有创建其他表。

我检查了不同的变体、不同的 liquibase 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。

请帮忙。可能有人使用 sql 或其他格式的回滚操作？哪里错了？我做错了什么？ liquibase 功能是否有效？

最佳答案

希望您仍然对帮助感兴趣，但据我所知，您没有包含 CASE-0-3 SQL 脚本，因此 liquibase 不知道您在 CASE-0-2 标记之外应用的更改提供 - 因此它无法回滚。

我的团队所做的是创建一个更强大的 changelog.xml 来引用我们的 .sql 脚本，而不是使用 .sql 脚本作为变更日志文件。

如果有帮助请告诉我!
