How to insert STRUCT values in Google Big Query? - sql

Question

We have standart analytics table in GoogleBigQuery:
We need to insert new data, with:
event_date,
event_timestamp,
event_name,
event_params.key.value,
event_params.value.string_value,
device.advertising_id
And I can't understand, how i can do it, with "event_params.key.value, event_params.value.string_value, device.advertising_id".
Can you help me make a request?
Somethink like this
INSERT
INTO `table`.`analytics_183424923.events_intraday_20191120`
(
`event_date`,
`event_timestamp`,
`event_name`,
`device.advertising_id`
)
VALUES
(
'20191120',
1574212435206765,
'custom_event',
'deviceId'
);
Here our table in JSON.
[

"event_date": "20191120",
"event_timestamp": "1574236440549659",
"event_name": "SHOW_INTERSTITIAL",

}
},
{

}
}
],

}
}
],

INSERT
INTO `table`.`analytics_183424923.events_intraday_20191120`
(
`event_date`,
`event_timestamp`,
`event_name`,
`device`
)
VALUES
(
'20191120',
1574212435206765,
'custom_event',
struct<category string, advertising_id string>('mobile', 'deviceId')
);
A simpler form would work in your case, but sometimes your have to specify the full field list of a struct as above.
Simpler one:
...
VALUES
(
'20191120',
1574212435206765,
'custom_event',
('mobile', 'deviceId')
);
