如何获取具有“generalinfo”值和“NA”而不是“NA”行的行？

【问题讨论】：

你应该看看 Oracle 的 JSON 解析函数。不要尝试对 JSON 内容使用正则表达式。

如果列数据类型不是 JSON 则尝试SELECT result FROM TABLE1 WHERE result like '%"generalinfo"":""Authorize-All-06262019"%'

你的数据库版本是多少？

WHERE result like '%"generalinfo":"Authorize-All-06262019"%'???

【参考方案1】：

如果您的数据库版本是 12c，那么只要您的列 (result) 的格式符合 json 格式，您就可以通过添加检查约束轻松找出：

alter table table1 
add constraints chk_result_json  
check(result is json);

并检查 generalinfo 不是 NA 为：

select * 
  from table1 t
 where t.result.generalinfo != 'NA'

使用treat(result AS json) as 更容易用于 18c 版本：

select *
  from ( select id, treat(result AS json) as result from table1 ) t
 where t.result.generalinfo != 'NA'

我安装了 DB 12.1.0.2，它也支持上述约束亲爱的@a_horse_with_no_name。
