liquibase无法在分区表上创建索引和唯一约束

问题描述

Liquibase文件如下：

databaseChangeLog：

  - changeSet:
      id: 1
      author: roran
      changes:
        - createTable:
            tableName: account_balance
            columns:
              - column:
                  name: id
                  type: bigint
                  autoIncrement: true
                  constraints:
                    primaryKey: true
              - column:
                  name: account_id
                  type: bigint
                  constraints:
                    nullable: false
              - column:
                  name: balance_date
                  type: date
                  constraints:
                    primaryKey: true
              - column:
                  name: create_date
                  type: timestamptz
              - column:
                  name: created_by
                  type: varchar(100)
              - column:
                  name: update_date
                  type: timestamptz
              - column:
                  name: updated_by
                  type: varchar(100)
        - modifysql:
            applyToRollback: false
            dbms: postgresql
            append:
              value: PARTITION BY RANGE (balance_date);
        - addUniqueConstraint:
            columnNames:  balance_date,account_id
            tableName:  account_balance
        - createIndex:
            columns:
              - column:
                  name:  account_id
            indexName:  account_id_idx
            tableName:  account_balance

启动Spring Boot应用程序时添加唯一约束时出现错误

更改集/db/changelog/changes/1.create-account-balance-table.yml::1::roran的迁移失败：原因：liquibase.exception.DatabaseException：错误：PARTITION Position或附近的语法错误：93 [失败的sql：（0）更改表public.account_balance添加唯一（balance_date，account_id）按范围分组（balance_date）；] \ tat org.springframework.beans.factory.support.AbstractAutowireCapablebeanfactory.initializeBean（AbstractAutowireCapablebeanfactory.java:1794 ）\ tat org.springframework.beans.factory.support.AbstractAutowireCapablebeanfactory.doCreateBean（AbstractAutowireCapablebeanfactory.java:594）\ tat org.springframework.beans.factory.support.AbstractAutowireCapablebeanfactory.createBean（AbstractAutowireCapablebeanfactory.java:516）\

类似地，我在启动Spring Boot应用程序时添加索引时遇到错误。

liquibase.exception.MigrationFailedException：迁移失败更改集db / changelog / changes / 1.create-account-balance-table.yml :: 1 :: roran：原因：liquibase.exception.DatabaseException：错误：语法错误在PARTITIOn位置或附近：[失败的sql：（0）创建索引account_id_idx ON public.account_balance_p0（account_id）PARTITION BY RANGE（balance_date）；创建表public.account_balance_p0 account_balance的分区，用于从（'2020-10-01 00:00:00'）到（'2020-11-01 00:00:00'）;] \ tat liquibase.changelog.ChangeSet的值。 execute（ChangeSet.java:646）\ tat liquibase.changelog.visitor.UpdateVisitor.visit（UpdateVisitor.java:53）\ tat liquibase.changelog.ChangeLogIterator.run（ChangeLogIterator.java:83）\ tat liquibase.Liquibase.update（ Liquibase.java:202）\ tat

如果我通过liquibase创建表，稍后以编程方式创建索引或添加约束，则如下所示

：

CREATE INDEX account_id_idx ON public.account_balance(account_id);

我在liquibase中对分区表使用yaml的方式是否有错误？

我正在使用带有弹簧启动2.3.3的postgresql 11版本和liquibase

解决方法

modifySql的{{1}}类型也适用于ChangeSet和addUniqueConstraint类型。生成的sql的异常是由于在createIndex和PARTITION BY RANGE创建过程中添加了Index。

只需将其分为两部分-一个创建表的ChangeSet和一个创建UniqueConstraint和Index的ChangeSet：

UniqueConstraint

和

  - changeSet:
      id: 1
      author: roran
      changes:
        - createTable:
            tableName: account_balance
            columns:
              ...
        - modifySql:
            applyToRollback: false
            dbms: postgresql
            append:
              value: PARTITION BY RANGE (balance_date);
