Snowflake cloud data platform 将CSV数据加载到雪花表

在尝试将以下数据加载到SnowFlake表中时，列会拆分为多个列，因为它是CSV文件

列数据：

{"Department":"Mens 
Wear","Departmentid":"10.1;20.1","customername":"john4","class":"tops wear","subclass":"sweat shirts","product":"North & Face 2 Bangle","style":"Sweat shirt hoodie - Large - Black"}

---

是否有其他方法将数据加载到单个列中。

最好的解决方案是在CSV文件中使用不同的分隔符而不是逗号。如果不可能，则可以使用不存在的分隔符接收数据，将整行作为一列，然后对其进行解析。当然，它不会像本机加载那样有效：

cat test.csv 
1,2020-10-12,Gokhan,{"Department":"Mens Wear","Departmentid":"10.1;20.1","customername":"john4","class":"tops wear","subclass":"sweat shirts","product":"North & Face 2 Bangle","style":"Sweat shirt hoodie - Large - Black"}

create file format csvfile type=csv FIELD_DELIMITER='NONEXISTENT';        

select $1 from @my_stage (file_format => csvfile );

create table testtable( id number, d1 date, name varchar, v variant );

copy into testtable from (
select 
split( split($1,',{')[0], ',' )[0], 
split( split($1,',{')[0], ',' )[1], 
split( split($1,',{')[0], ',' )[2], 
parse_json( '{' || split($1,',{')[1]  )  
from @my_stage (file_format => csvfile )
);

select * from testtable;


+----+------------+--------+-----------------------------------------------------------------+
| ID |     D1     |  NAME  |                                V                                |
+----+------------+--------+-----------------------------------------------------------------+
|  1 | 2020-10-12 | Gokhan | { "Department": "Mens Wear", "Departmentid": "10.1;20.1", ... } |
+----+------------+--------+-----------------------------------------------------------------+

您的文件格式/复制到语句是什么？您可以创建一个带有变量列的表，并插入解析为JSON的数据。正如@Marcel所说，请分享整行数据，而不仅仅是一列数据——以及你是如何加载的
