Liquibase 根据 table 名称前缀在数据库上生成更改日志
Liquibase generate change log on db based on table name prefix
我可以根据 table 名称前缀从数据库生成 Liquibase 变更日志吗？
示例：
如果我有一个数据库模式并且它有以下 tables:
abc
abcd
abcdef
xyz
我只想为从 "abc" 开始的 table 生成 ChangeLog。所以 tables
的更新日志
abc,
abcd,
abcdef
有人可以帮助我吗？
如果您使用的 liquibase 版本 > 3.3.2，则可以使用 maven 或 liquibase 命令行。
Liquibase 3.3.2 is officially released. It is primarily a bugfix
release, but has one major new feature: object
diffChangeLog/generateChangeLog object filtering.
includeObjects/excludeObjects logic
You can now set an includeObjects or excludeObjects paramter on the
command line or Ant. For maven, the parameteres are diffExcludeObjects
and diffIncludeObjects. The format for these parameters are:
An object name (actually a regexp) will match any object whose name matches the regexp.
A type:name syntax that matches the regexp name for objects of the given type
If you want multiple expressions, comma separate them
The type:name logic will be applied to the tables containing columns, indexes, etc.
NOTE: name comparison is case sensitive. If you want insensitive
logic, use the (?i) regexp flag.
Example Filters:
“table_name” will match a table called “table_name” but not “other_table” or “TABLE_NAME”
“(i?)table_name” will match a table called “table_name” and “TABLE_NAME”
“table_name” will match all columns in the table table_name
“table:table_name” will match a table called table_name but not a column named table_name
“table:table_name, column:*._lock” will match a table called table_name and all columns that end with “_lock”
所以尝试在 generateChangeLog 命令中使用 excludeObjects 或 includeObjects 参数
更新
我使用过 liquibase 命令行，这个命令可以解决问题（对于 mysql 数据库）：
liquibase
--changeLogFile=change.xml
--username=username
--password=password
--driver=com.mysql.cj.jdbc.Driver
--url=jdbc:mysql://localhost:3306/mydatabase
--classpath=mysql-connector-java-8.0.18.jar
--includeObjects="table:abc.*"
generateChangeLog
这适用于我 Windows 10:
liquibase.properties:
changeLogFile=dbchangelog.xml
classpath=C:/Program\ Files/liquibase/lib/mysql-connector-java-8.0.20.jar
driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/liquibase?serverTimezone=UTC
username=root
password=password
schemas=liquibase
includeSchema=true
includeTablespace=true
includeObjects=table:persons
