在 postgresql 的 jsonb[] 类型列中插入数据的正确语法是什么答案

【问题标题】：What is the correct syntax of inserting the data inside the jsonb[] type column inside postgresql在 postgresql 的 jsonb[] 类型列中插入数据的正确语法是什么
【发布时间】：2021-12-22 18:12:13
【问题描述】：

既然我们只能在 jsonb 列中存储 json 对象的数组，那么为什么要使用 jsonb[]。我试图通过简单地将 jsonb 对象数组从 jsonb 列复制到 jsonb[] 列来将数据插入 jsonb[] 中。但是出现错误“格式错误的数组文字：必须引入明确指定的数组维度”。

【问题讨论】：

jsonb[] 几乎没有意义。将列的类型更改为jsonb，然后您可以直接插入您的值，没有任何问题。
为什么要使用 jsonb[] 我不知道有什么理由这样做。
是的，插入和检索过程完全适用于 jsonb 类型。

标签： c# arrays postgresql .net-core jsonb

【解决方案1】：

试试这个：inserting-jsonb-data-in-postgresql-9-6

文档：该功能从 postgres 9.6 开始存在， funtions-jsonb-postgresql

简单插入也应该可以。例如：

 INSERT INTO orders (info)
    VALUES('{ "customer": "John Doe", "items": {"product": "Beer","qty": 6}}');
