[英]JSON EXTRACT IN BIG QUERY
I Currently have a column in json format with multiple items.我目前有一个 json 格式的列,其中包含多个项目。 The struct is like the following:
结构如下:
phones": [{"phone": "11111111", "type": "CELLPHONE"}, {"phone": "222222222", "type":"CELLPHONE"}, {"phone": "99999999", "type": "CELLPHONE"}]
电话”:[{“电话”:“11111111”,“类型”:“手机”},{“电话”:“222222222”,“类型”:“手机”},{“电话”:“99999999”,“类型”:“手机”}]
I tried: json_extract(Contacts,'$.phones.phone') as phone_number but it only extracts the first one.我试过: json_extract(Contacts,'$.phones.phone') as phone_number但它只提取第一个。
JSON_EXTRACT_ARRAY(Contacts,'$.phones') as phone_contacts gives me an array, But Im getting error trying to unnest it. JSON_EXTRACT_ARRAY(Contacts,'$.phones') as phone_contacts给了我一个数组,但我在尝试解除嵌套时出错。
Does anybody know any approach to solve this problems?有人知道解决这个问题的任何方法吗?
Thanks in Advance.提前致谢。
