使用 Oracle SQL 解析 Json

Question

I am trying to parse JSON in Oracle SQL.

Oracle DB version 12.1.0.2

{
 "Rownum": "1",
 "Name": "John",
 "AddressArray":["Address1", "Address2"],
 "TextObj":[{
             "mName" : "Carol",
             "lName" : "Cena"
            },
            {
             "mName" : "Mark",
             "lName" : "Karlo"
            }
           ]
}

output should look like below:

Answer 1

I suppose "nested" will do the trick

select * from json_Table('{"Rownum": "1", "Name": "John", "AddressArray":["Address1", "Address2"], "TextObj":[{"mName" : "Carol","lName" : "Cena",}]}', '$' columns (rownr number path '$.Rownum',
                                            name varchar2(100) path '$.Name',
                                            mName varchar2(100) path '$.TextObj[*].mName',
                                            lName varchar2(100) path '$.TextObj[*].lName',
                                            nested path '$.AddressArray[*]' columns(AddressArray varchar2(100) path '$') 
                                           ));

My output:

ROWNR	NAME	MNAME	LNAME	ADDRESSARRAY
1	John	Carol	Cena	Address1
1	John	Carol	Cena	Address2
