When this occurs, the target row is called a multi-joined ...Using the FLATTEN Function to Parse Arrays¶ Parse an array using the FLATTEN function. FLATTEN is a table function that produces a lateral view of a VARIANT, OBJECT, or ARRAY column. The function returns a row for each object, and the LATERAL modifier joins the data with any information outside of the object.Snowflake maintains statistics on tables and views, and this optimization allows simple queries to run faster. When a row access policy is set on a table or view and the COUNT function is used in a query, Snowflake must scan each row and determine whether the user is allowed to view the row.Jul 8, 2019 ... gardner (Snowflake)​ This does work although it's a bit dirtier.

In JSON, an object (also called a “dictionary” or a “hash”) is an unordered set of key-value pairs. TO_JSON and PARSE_JSON are (almost) converse or reciprocal functions. The PARSE_JSON function takes a string as input and returns a JSON-compatible VARIANT. The TO_JSON function takes a JSON-compatible VARIANT and returns a string.

An aggregate function takes multiple rows (actually, zero, one, or more rows) as input and produces a single output. 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 ...Ok, interesting. So the ::variant is indicating that there are other elements in the arrays as well?
