The number of fractional decimal digits (from 0 toprecision- 1). 0 indicates no fractional digits (i.e. an integer number). The default scale is 0. Returns The function returnsNUMBER(precision,scale). If theprecisionis not specified, then it defaults to 38. ...
Result Scan 因为结果集被持久化在 Blob Storage 上,所以 Snowflake 支持在 SQL 中使用内置的 Table Function 查询之前的结果集,并且对结果集的 data 进行 projection、aggregation 和 join 等操作: -- suppose query id is abc123selectc1,c2fromorders;-- result scanselectc1,c2fromtable(result_scan('abc123...
