Here is my json data:
{
"TransactionId": "1",
"PersonApplicant": [
{
"PersonalId": "1005",
"ApplicantPhone": [
{
"PhoneType": "LANDLINE",
"PhoneNumber": "8085063644",
"IsPrimaryPhone": true
}
]
},
{
"PersonalId": "1006",
"ApplicantPhone": [
{
"PhoneType": "LANDLINE",
"PhoneNumber": "9643645364",
"IsPrimaryPhone": true
},
{
"PhoneType": "HOME",
"PhoneNumber": "987654321",
"IsPrimaryPhone": false
}
]
}
]
}
I want to get phone no of the people who have phonetype as landline. How to do that?
I tried this approach:
#find phoneNumber when phoneType='LANDLINE'
SELECT
@path_to_name := json_unquote(json_search(applicationData, 'one', 'LANDLINE')) AS path_to_name,
@path_to_parent := trim(TRAILING '.PhoneType' from @path_to_name) AS path_to_parent,
@event_object := json_extract(applicationData, @path_to_parent) as event_object,
json_unquote(json_extract(@event_object, '$.PhoneNumber')) as PhoneNumber
FROM application;
The issue with this is that I am using 'one' so I am able to achieve results but here in my json I have 2 people who have type as landline. Using json search I am getting array of values and I am not able to decide how to extract these array row values in a manner where I can extract paths.
SELECT
@path_to_name := json_unquote(json_search(applicationData, 'all', 'LANDLINE')) from application;
result:
as you can see at 3rd and 4th row i am getting 2 data as an array.
How do I store this data to get the appropriate result?
I also tried one more query but not able to retrieve results for array of data.
I cannot use stored procedure and I have to use mysql workbench.
Please note that I am fresher so I don't know how I can approach this solution for more complex queries where I may have to retrieve id of a person having type as landline (multiple people in single array).
SELECT test.id, jsontable.*
FROM test
CROSS JOIN JSON_TABLE(test.data,
'$.PersonApplicant[*]'
COLUMNS ( PersonalId INT PATH '$.PersonalId',
PhoneType VARCHAR(255) PATH '$.ApplicantPhone[0].PhoneType',
PhoneNumber VARCHAR(255) PATH '$.ApplicantPhone[0].PhoneNumber')) jsontable
WHERE jsontable.PhoneType = 'LANDLINE';
