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:Value to find in array.

The ARRAY to search. Returns¶ The function returns TRUE if value is present in array. Examples¶

If you have the data in a VARIANT (in its raw form) you should be able to flatten the array into rows using LATERAL FLATTEN. For example if you had a table my_json with a VARIANT field raw_json, you could do something like: SELECT rs.value AS result_row. FROM my_json. LATERAL FLATTEN(INPUT => raw_json:result) rs. ;

Heres an alternative form using OBJECT_AGG with LATERAL FLATTEN that avoids the potential support issue of PIVOT with ARRAY_AGG proposed by Adrian White.. This should work for any aggregates on multiple input columns included within the initial ARRAY_CONSTRUCT in the OBJ_TALL CTE. I expect that the conditional aggregation …

Separators for records (for example, new line characters). Although the name (CSV) suggests comma-separated values, you can use any valid character as a field separator. JSON (for loading or unloading) Any plain text file containing one or more JSON documents (such as objects or arrays). In Snowflake Scripting, a RESULTSET is a SQL data type that points to the result set of a query. Because a RESULTSET is just a pointer to the results, you must do one of the following to access the results through the RESULTSET: Use the TABLE(...) syntax to retrieve the results as a table. Iterate over the RESULTSET with a cursor.

In contrast, scalar functions take one row as input and produce one row (one value) as output. An aggregate function always returns exactly one row, even when the input contains zero rows. Typically, if the input contained zero ...Semi-structured Data Files and Columnarization.
