A window function is any function that operates over a window of rows. A window function is generally passed two parameters: A row. More precisely, a window function is passed 0 or more expressions.

This works: SELECT * FROM TableA WHERE Col1 IN ('Value1', 'Value2', 'Value3'); But I can't figure out how to create a variable from that manually specified array to use. I want to do something like this:SPLIT. Splits a given string with a given separator and returns the result in an array of strings. Contiguous split strings in the source string, or the presence of a split string at the beginning or end of the source string, results in an empty string in the output. An empty separator string results in an array containing only the source string.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. ;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.

It is possible without using FLATTEN, by using ARRAY_UNION_AGG: Returns an ARRAY that contains the union of the distinct values from the input ARRAYs in a column. For sample data: Query: or: UNION ALL. SELECT Herbs FROM t); Output: You could flatten the combined array and then aggregate back:from arr. pivot(col_name for col_value in ('category', 'subcategory', 'subsubcategory') as p (id, category, subcategory, subsubcategory); It is possible to use the following approach, but it is flawed in that any time a new custom field is added I have to add cases to account for new positions within the array. select.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 … Extracts a value from an ARRAY or an OBJECT (or a VARIANT that contains an ARRAY or OBJECT).
