ARRAY VARIANT可以存储其它数据类型,包含OBJECT或ARRAY本身,只要其大小压缩后小于16MB就可以。OBJECT和ARRAY是VARIANT的一种特例,类似于JSON中的对象和数组。而且VARIANT、OBJECT、ARRAY都支持嵌套。所以,其表达能力是很强的。 关于半结构化的数据类型,详细可以参考:https://docs.snowflake.com/en/sql-reference/data-ty...

对于“JSON”格式,直接复制只支持以下情况:源 Snowflake 表或查询结果仅有一列且该列的数据类型是“VARIANT”、“OBJECT”或“ARRAY” 。 compression 可为“无压缩”、 gzip、bzip2 或deflate。 encodingName 保留为默认值或设置为 utf-8。 filePattern 在复制活动接收器中保留为默认值...
snowflake-cloud-data-platform 1个回答 0投票 VARIANT 同时包含 JSON 和 ARRAY,因此,JSON 的 ARRAY 仍然是 VARIANT。 它不执行类型/形状强制。它只是一个任何类型。 因此一些数据通过PARSE_JSON变成了VARIANT: select $1 as str, PARSE_JSON(str) as json, TYPEOF(json) as type, SYSTEM$TYPEOF(json) ...
