# 南大通用GBASE 8.5S 实施经验
南大通用GBASE移植过程中的注意事项和文档。以下内容只是应用于GBase 8s v8.7, 其他版本如GBase 8a并不适用。感谢来自原厂工程师的支持。
## 体验GBASE版的零售供应链系统
https://demo.doublechaintech.com/admin/retailscmgbase/
## 启动和停止
onmode -ky && oninit -v
## GBASE 类型
* text 不支持用sql插入, 内容不多可以用varchar(320000)代替
* bool就是boolean，值是 'T'=true, 'F'= false
## 切换数据库
* 用database 来切换, 比如 database erpdatabase
## GBASE 约束
* 约束的名字在最后面
## 分页查询
* select * from user limit 10, 10 可以工作，但是该种模式下，位置不能通过PreparedStatement参数来设置，不要用于编程环境
* select skip 2 first 2 * from user 也可以工作，改模式可以通过PreparedStatement参数来设置，推荐在程序中使用
* Oracle那种模式也能工作，还没有测试过
## 命令行工具 dbaccess
* 导入文件 dbaccess - import.sql
## 设置日期格式
在文件profile.gbaseserver中设置
export GL_DATE=%Y-%m-%d
## JDBC连接和解决中文问题
* 连接字符串jdbc:gbasedbt-sqli://47.99.97.125:9088/gbasedb:gbasedbtserver=gbaseserver;db_locale=zh_cn.utf8;client_locale=zh_cn.utf8;NEWCODESET=utf-8,utf8,57372;
* 驱动类名称 com.gbasedbt.jdbc.IfxDriver
* 试用GB18030的连接字符串db_locale=zh_cn.gb18030-2000;client_locale=zh_cn.gb18030-2000;NEWCODESET=gb18030,gb18030-2000,5488;
* 用户名，安装该软件的用户名
* 密码，安装该软件的密码
## JDBC解决中文问题(JDBC抛出SQLEXCEPTION，提示出现Locale mismatch）
```
先以原来身份进入
unset DB_LOCALE CLIENT_LOCALE
解决方案，要在../profile.gbaseserver 设置
export CLIENT_LOCALE=zh_cn.utf8
export DB_LOCALE=zh_cn.utf8
export SERVER_LOCALE=zh_cn.utf8
执行source ../profile.gbaseserver后，重新导入
```
通过 执行查询，如果出现类似下面结果相应的数据库dbs_collate=zh_CN.57372则认为正确
```
> database his;
Database selected.
> select * from sysmaster:sysdbslocale;
dbs_dbsname sysmaster
dbs_collate en_US.819
dbs_dbsname sysutils
dbs_collate en_US.819
dbs_dbsname sysuser
dbs_collate en_US.819
dbs_dbsname sysadmin
dbs_collate en_US.819
dbs_dbsname residentialquarter
dbs_collate zh_CN.57372
dbs_dbsname retailscm
dbs_collate zh_CN.57372
dbs_dbsname his
dbs_collate zh_CN.57372
7 row(s) retrieved.
```
## 解决Grouby子句包含函数问题
* 这样不能工作 select date(update_time) ,count(*) as count from expense_type_data group by date(update_time) ;
* 这样可以工作 select date(update_time) as date_key, count(*) as count from expense_type_data group by date_key ;
## 启动和停止日志
