替换 postgresql jsonb 数组对象中的撇号 ( ' )

Question

请找到下面的 jsonb 对象，我需要在其中替换指令密钥中的所有撇号。

    [{
        "instruction": "Don't need to book car for M'lore location",
        "reservationNo": "TT00098272"
    },
    {
        "instruction": "Please book a car for mumbai location",
        "reservationNo": "TT00098273"
    }
 ]

预期结果：值被替换为撇号

[{
            "instruction": "Dont need to book car for Mlore location",
            "reservationNo": "TT00098272"
        },
        {
            "instruction": "Please book a car for mumbai location",
            "reservationNo": "TT00098273"
        }
     ]

Answer 1

您可以在投射到 text 后执行 regexp_replace():

postgres=# create table j (field jsonb);
CREATE TABLE
postgres=# insert into j values ('[{
postgres'#         "instruction": "Don''t need to book car for M''lore location",
postgres'#         "reservationNo": "TT00098272"
postgres'#     },
postgres'#     {
postgres'#         "instruction": "Please book a car for mumbai location",
postgres'#         "reservationNo": "TT00098273"
postgres'#     }
postgres'#  ]'::jsonb);
INSERT 0 1
postgres=# select regexp_replace(field::text,'''','','g')::jsonb from j;
                                                                                    regexp_replace                                                                                     
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 [{"instruction": "Dont need to book car for Mlore location", "reservationNo": "TT00098272"}, {"instruction": "Please book a car for mumbai location", "reservationNo": "TT00098273"}]
