在 postgresql 中的 jsonb[] 類型列中插入數據的正確語法是什么

Question

由於我們只能在 jsonb 列中存儲 json 對象數組，那么為什么要使用 jsonb[]. 我試圖通過簡單地將 jsonb 對象數組從 jsonb 列復制到 jsonb[] 列來將數據插入到 jsonb[] 中。 但是出現錯誤“格式錯誤的數組文字：必須引入明確指定的數組維度”。

Answer 1

試試這個： inserting-jsonb-data-in-postgresql-9-6

文檔：該函數從 postgres 9.6 開始存在， funtions-jsonb-postgresql

簡單插入也應該有效。 例如：

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