雪花 - 无效的标识符

Question

您好，我在下面执行此查询时收到无效的“所有者”标识符，我尝试了单引号/双引号和 tilda

在显示角色中，我有带有电子邮件地址的 cmets，我正在尝试获取所有者和所有者的电子邮件地址。

cmets 示例 - {RoleType:"Access",Workload:"RTR",Application:"Business Automation",AppName:"RTR",Contact:"sabfinw@gmail.com",Director:"sabrish133@gmail.com ",环境:"DEV",所有者:"sanjayd.980@gmail.com",VP:"sabrish"}

show roles;

    select owner,split_part(b.data,':',2) as Owner_Email from (
        select a.value::string as data from TABLE(RESULT_SCAN(LAST_QUERY_ID())),
        lateral flatten(input=>split("comment",',')) a) b where b.data like '%Owner%';

Answer 1

您需要从内部选择中选择值

SELECT 
    owner,
    split_part(b.data,':',2) as Owner_Email 
FROM (
    SELECT r.owner,
        a.value::string as data
    FROM TABLE(RESULT_SCAN(LAST_QUERY_ID())) r,
    LATERAL FLATTEN(input=>split(r.comment, ',')) a
) b 
WHERE b.data LIKE '%Owner%';

或者您可以使用 QUALIFY 子句同时过滤：

SELECT r.owner,
    split_part(a.value::string, ':', 2) as Owner_Email
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID())) r,
LATERAL FLATTEN(input=>split(r.comment, ',')) a
QUALIFY a.value::string LIKE '%Owner%'
