The keys of this list define the column names of the table, and the types are inferred by sampling the whole dataset, similar to the inference that is performed on JSON files. For information about storage requirements of the numeric data types, see Section 11.7, “Data Type Storage Requirements”. For descriptions of functions that operate on numeric values, see Section 12.6, “Numeric Functions and Operators”. The data type used for the result of a calculation on numeric operands depends on the types of the ... 1) Single Row Functions: Single row or Scalar functions return a value for every row that is processed in a query. 2) Group Functions: These functions group the rows of data based on the values returned by the query.
