用于提取 JSON 数据的 PostgreSQL 查询

Question

我在列 codemap 中有 json 数据，从不同的编码参数类别（例如 cpt drg、modifiers、secondaryDiagnosis、principalDiagnosis、secondaryProcedure、observationhours、dischargeStatus、principalprocedure）中提取的代码（属于删除、修改或添加需要从中提取） ,hcpcs) 需要被提取

我的输入和预期数据的一些图像如下：

下面是我的 JSON 数据的样子

下面也是我的输入和输出表的样子。

108565-input-data-1.jpg 108546-input-data-2.jpg 108547-output.jpg

输入数据：

预期输出：

我对代码的尝试：

SELECT JSONB_ARRAY_ELEMENTS(codemap->'secondardiagnosis' ->'added' ->> 'code') 
    AS secondarydiagnosisaddedcodeadded, * 
  FROM qa_score_report

我没有得到任何输出。 我可以尝试什么来解决这个问题？

Answer 1

您为数组函数提供了一个字符串（ code ）。 首先解析added的数组并使用结果集解析code ：

SELECT jsonb_array_elements(codemap->'secondaryDiagnosis'->'added')->'code' 
FROM qa_score_report;

将code聚合为一行

SELECT array_to_string(array_agg(trim('"' FROM j::text)),',') 
FROM (SELECT jsonb_array_elements(codemap->'secondaryDiagnosis'->'added')->'code'
      FROM qa_score_report) i (j);
