@Table("system_user")
@TableIndexes({ @Index(name = "user_name", fields = { "username" }, unique = true) })
@View("v_system_user")
public class User{
   	@Column
	@ColDefine(type = ColType.PSQL_JSON)
	private List<Integer> organizations;

	@Column
	@ColDefine(type = ColType.PSQL_JSON)
	private List<String> factorys;
}

问题1. 新增字段organizations和factorys，在MvcSetup初始化方法时Daos.migration(dao, "包名", true, true);出现以下错误“

          if (log.isDebugEnabled())
              log.debugf("migration Table '%s' fail!", en.getTableName(), e);
         }

其中meta.getTableName(1)获取表名为空，而 en.getTableName()能获取代码中的表名

问题2. 我要添加ColType.PSQL_JSON字段，对应Oracle的字段实际上类型竟然是JSON类型，请问有这个类型吗？
类OracleJdbcExpert、AbstractJdbcExpert，方法evalFieldType，其中解析PSQL_JSON类型是JSON

case PSQL_JSON:
            return "JSON";

问题3. 我尝试升级到1.r.58版本，结果发现还没有跑到数据表处理这块，就在合并sql方法中给跪了

原因是Daos类migration方法：

// show index from mytable;
                    String showIndexs = "show index from " + en.getTableName();
                    PreparedStatement ppstat = conn.prepareStatement(showIndexs);
                    ResultSet rest = ppstat.executeQuery();
                    while (rest.next()) {
                        String index = rest.getString(3);
                        _indexs.add(index);
                    }

请问Dao是否支付oracle数据库。

跪求解决！

7 回复

额, 你想在Oracle中操作类似JSON类型的属性? 还是为了兼容一下数据库而已??

问题1和问题2出现的版本是1.b.53
问题3出现的版本是1.r.58

@wendal
java代码中字段属性是list，想直接转换成json保存到数据库

如果只是为了兼容, 修改org.nutz.dao.impl.jdbc.oracle.OracleJdbcExpert.evalFieldType(MappingField)的实现应该能解决

@wendal
恩，如果要额外编写nutz，我想一下其它类型方案

嗯, ColDefine设置一下适配器咯,然后不需要指定type用VARCHAR就好了

ColType.PSQL_JSON 本来就是只给 postgrsql 用的
