因为Snowflake数组基本上是JSON数组，所以ARRAY_AGG返回的数组可以直接写入JSON文件。
PUT file:///tmp/simple_zipcodes.json @~/tmp; COPY INTO– Load the JSON file into Snowflake table Once you upload the JSON file to the internal stage, now use theCOPY INTOtablename command to load the JSON file to the Snowflake database table. COPY INTO ZIPCODE_JSON from '@%ZIPCODE_...
那接下来我们终于可以像Snowflake那样来访问数据了(直接把content由STRING CAST 为这个复杂的STRUCT是无法成功的,这里用了一个 Spark的专用函数 FROM_JSON)。 SELECTcontent.os,content.priceFROM(SELECTFROM_JSON(content,'struct<app_version:string,city:string,commodityname:string,commoditynumber:bigint,country:stri...
函数构造为嵌套 JSON)流式传输到 Kafka 主题。我想仅使用配置来实现此目的,而不使用自定义编码。 我设法设置一个 JDBC 源连接器,将消息发送到执行以下查询的 Kafka 主题: select object_construct( 'id', id, 'nestedField', object_construct( 'nestedvalue', value ) ) as myRecord from myTable; 使用 ...

select * from iceberg_scan('s3://chapter-platform-iceberg/icebergs/line_item'); Theiceberg_scan方法从 S3 获取表数据。你无需显式指定当前的manifest.json文件,因为version-hint.text文件指定了表的当前版本。 我们现在真正释放了开放表格式技术的强大功能:我们享受到了Snowflake的便利及其目录功能,同时通过在Du...
我有一个Alteryx工作流,它从snowflake表中选择所有内容,向表中添加RecordId列,然后使用新名称将结果上传回snowflake。问题是: Snowflake不能识别RecordID列。如果我使用SELECT * FROM NUMBERED_TABLE,它会成功读取整个表,显示每个字段,包括RecordID。NUMBERED_TABLE进行选择,则会得到消息SQL compilat ...
