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. The data type of the returned value is ARRAY. Usage Notes¶ The data types of the inputs may vary. If the function is called with N arguments, the size of the resulting array will be N. In many contexts, you can use an ARRAY constant (also called an ARRAY literal) instead of the ARRAY_CONSTRUCT function. Examples¶

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.

I'm trying to insert multiple rows with arrays and structs, via an SQL statement, into Snowflake. To insert arrays of values into a column I am using the ARRAY_CONSTUCT function and to insert the structures/dictionaries/objects I am using the OBJECT_CONSTRUCT function. E.g. insert into "MY_DB"."MY_SCHEMA"."MY_TABLE".The source array. Usage Notes¶ Semi-structured data (e.g. JSON data) can contain explicit null values, which are distinct from SQL NULLs. A null value in semi-structured data indicates a missing value. array1 should be either an ARRAY data type or a VARIANT data type containing an array value. If the argument is NULL, the result will be NULL.FLATTEN. Flattens (explodes) compound values into multiple rows.

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.You can use the (LATERAL) FLATTEN function to extract a nested variant, object, or array from JSON data. For example, let's create a table VNT containing a single JSON field: CREATE OR REPLACE TABLE vnt. src variant. AS SELECT parse_json (column1) as src. FROM values.The source array. Usage Notes¶ Semi-structured data (e.g. JSON data) can contain explicit null values, which are distinct from SQL NULLs.

You can use the (LATERAL) FLATTEN function to extract a nested variant, object, or array from JSON data. For example, let's create a table VNT containing a single JSON field: CREATE OR REPLACE TABLE vnt. src variant.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 ...October 17, 2022. Solution. Working with semi-structured data sometimes requires adding a row to the table containing such data. Let's take a look at how ARRAY data can be added to a table. CREATE OR REPLACE TABLE TEST_INSERT_INTO_VARIANT (COL1 NUMBER, COL2 VARIANT); As long as the array is numeric this can be done quite easily:This 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:The data type of the returned value is ARRAY. Usage Notes¶ The data types of the inputs may vary. If the function is called with N arguments, the size of the resulting array will be N. In many contexts, you can use an ARRAY constant (also called an ARRAY literal) instead of the ARRAY_CONSTRUCT function.

See also: GET_IGNORE_CASE, GET_PATH , : Syntax¶ ARRAY (or VARIANT containing an ARRAY)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: Takes an ARRAY value as input and returns the size of the array (i.e. the largest index + 1). If the array is a sparse array, this means that the size includes the undefined elements as well as the defined elements. A NULL argument returns NULL as a result.
