标签：hibernate postgresql kingbase ts Kingbase sys pg PostgreSQL 对比
近日，公司的某软件产品——原本使用 PostgreSQL 数据库——需要支持人大金仓 （Kingbase） 数据库。据了解，Kingbase 是基于 开源数据库 PostgreSQL 开发的，大部分功能与 PostgreSQL兼容。Kingbase 8 是基于 PostgreSQL 9.6 的。本文列举发现的 PostgreSQL 9.6 与 Kingbase 8 的差异对比。
1 JDBC
|
| postgresql 9.6 | kingbase 8 |
| driver_class | org.postgresql.Driver | com.kingbase8.Driver |
| url | jdbc:postgresql://127.0.0.1:5432/postgres | jdbc:kingbase8://127.0.0.1:54321/kingbase |
| jdbc 的 jar | postgresql.jdbc-9.0.jar <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql.jdbc</artifactId> <version>9.0</version> </dependency> | kingbase8-8.2.0.jar <groupId>com.kingbase8</groupId> <artifactId>kingbase8-jdbc</artifactId> <version>8.2.0</version> </dependency> |
| hibernate 的jar | hibernate-5.0.12.jar <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate</artifactId> <version>5.0.12</version> </dependency> | hibernate-3.6.0-dialect-1.0.jar <dependency> <groupId>com.kingbase</groupId> <artifactId>hibernate-3.6.0-dialect</artifactId> <version>1.0</version> </dependency> |
| hibernate方言 | org.hibernate.dialect.PostgreSQL9Dialect | org.hibernate.dialect.Kingbase8Dialect |
这里127.0.0.1 表示本地的ip地址。
5432 是postgresql的默认端口；54321则是达梦的默认端口。
postgres 是postgresql默认的数据库名，kingbase是Kingbase默认的数据库名。
这些参数可根据实际调整。
2 命令程序
| postgresql 9.6 | kingbase 8 |
| pgbench | kbbench |
| postgres | kingbase |
| psql | ksql |
| pg_archivecleanup | sys_archivecleanup |
| pg_basebackup | sys_basebackup |
| pg_bulkload | sys_bulkload |
| pg_config | sys_config |
| pg_controldata | sys_controldata |
| pg_ctl | sys_ctl |
| pg_dump | sys_dump |
| pg_dumpall | sys_dumpall |

可以看到，这里kingbase只是将postgresql 的表的前缀从 pg 改成了 sys 或者 kb。
