If you would parse 100 rows, you would get the sequences 1 till 100. a key. Only relevant for maps and objects. the path. Which is a pointer to the location of the element within the original structure. the index. Only applicable for arrays and the same as the path (only the data types are different). the value of the element.You can partition by 0, 1, or more expressions. For example, suppose that you are selecting data across multiple states (or provinces) and you want row numbers from 1 to N within each state; in that case, you can partition by the state. If you want only a single group, then omit the PARTITION BY clause. expr3 and expr4 specify the column (s) or ...As you noticed yourself, you want 4 records. There are 2 ways to do it, both exploit the index column produced by flatten, which represents the position of the produced value in the input (see the Flatten Documentation). Using 2 flattens and index-selection. First way is to take the result of your query, and add these index column, here's an example:array. The source array. new_element. The element to be appended. The type of the element depends on the type of the array: If array is a semi-structured ARRAY, the element may be of almost any data type. The data type does not need to match the data type(s) of the existing elements in the array.

For each (key, value) input pair, where key must be a VARCHAR and value must be a VARIANT, the resulting OBJECT contains a key: value field. Aliases: OBJECTAGG. Syntax¶ARRAY¶ A Snowflake ARRAY is similar to an array in many other programming languages. An ARRAY contains 0 or more pieces of data. Each element is accessed by specifying its position in the array. Characteristics of an ARRAY¶ Each value in a semi-structured ARRAY is of type VARIANT. (A VARIANT can contain a value of any other data type.)ARRAY_CONSTRUCT — Returns an array based on the inputs. ARRAY_AGG — This function will accept input values and pivot them into an array, allowing a group of values to be returned for each row. Rather than performing an aggregate function against the values, such as SUM or AVG, they are pivoted into a list. PIVOT. Rotates a table by turning the unique values from one column in the input expression into multiple columns and aggregating results where required on any remaining column values. In a query, it is specified in the FROM clause after the table name or subquery. The operator supports the built-in aggregate functions AVG , COUNT, MAX , MIN ...
