Value to find in array. If array is a semi-structured ARRAY, value_expr must evaluate to a VARIANT. If array is a structured ARRAY, value_expr must evaluate to a type that is comparable to the type of the ARRAY. array. The ARRAY to search. Returns¶ The function returns TRUE if value is present in array. Examples¶Snowflake Scripting supports the following types of loops: FOR. WHILE. REPEAT. LOOP. This topic explains how to use each of these types of loops. FOR loop¶ A FOR loop repeats a sequence of steps for a specified number of times or for each row in a result set. Snowflake Scripting supports the following types of FOR loops: Counter-based FOR loops to_array¶. 入力式を array に変換します。 入力が array、または配列値を含む variant の場合、結果は変更されません。 null または json null 入力の場合、 nullを返します。 その他の値の場合、結果はこの値を含む単一要素の配列です。 The function returns an ARRAY containing the distinct values in the specified column. The values in the ARRAY are in no particular order, and the order is not deterministic. The function ignores NULL values in column. If column contains only NULL values or the table containing column is empty, the function returns an empty ARRAY.

The following examples demonstrate how to use the aggregation functions that produce ARRAYs of distinct values as an alternative to COUNT(DISTINCT <expression>). Example 1: Counting the Distinct Values in a Single Table. Example 2: Using GROUP BY to Compute the Counts by Group. Example 3: Using GROUP BY ROLLUP to Roll up Counts by Group.create or replace table demo_db.public.snowball ( table_name varchar(314), total_rows number(18,0), table_last_altered timestamp_ltz(9), table_created timestamp_ltz(9), table_bytes number(18,0), col_name array, col_data_type array, col_hll array, col_null_cnt array, col_min array, col_max array, col_top array, col_avg array, …Creates rows of data based either on a specified number of rows, a specified generation period (in seconds), or both. This system-defined table function enables synthetic row generation. Note that it is possible to generate virtual tables with 0 columns but possibly many rows. Such virtual tables are useful for queries whose SELECT clause ...

(1, 'ts1', '[1,2,3]'), (2,'ts2','[7,8,9]'); There are two types of filtering when Snowflake analyzes a query to minimize the table scan (from your screenshot it appears this is where most of the time is spent in your query) Static pruning - filters, ensure that you do not apply functions on the column itself but where you can apply functions on the static value of your queryThis shows a simple query using FIRST_VALUE(). This query contains two ORDER BY sub-clauses, one to control the order of rows in each partition, and one to control the order of the output of the full query. The next query contrasts the outputs of FIRST_VALUE, NTH_VALUE, and LAST_VALUE. Note that: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:

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.

The following example returns an ARRAY containing a range of numbers starting from -5 and ending before -25, decreasing in value by -10: SELECT ARRAY_GENERATE_RANGE (- 5 , - 25 , - 10 ); Copy

SELECT parse_json(column1) as json.This function returns an ARRAY that is constructed by concatenating the ARRAYs in array. If array is NULL or contains any elements that are NULL, the function returns NULL. Usage Notes¶ If array contains multiple levels of nested ARRAYs, the function only removes one level of nesting. For example, if the input ARRAY is: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.

One possible solution is to create a javascript function and use the javascript .map() to apply a function to each element of the array: create or replace function extract_tags(a array) returns array language javascript strict as ' return A.map(function(d) {return d.tag}); '; SELECT ID, EXTRACT_TAGS(PAYLOAD:tags) AS tags from t1; 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.
