Snowflake array to rows.

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. 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 ... 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. Examples¶ Here is a simple example: Explode Array to Rows: Using Snowflake Flatten Function & Lateral. The FLATTEN function is a table function that explores the values of an object or array object into rows. A lateral perspective is created by using the flatten function. When converting array data to table rows, the flatten function is most typically employed.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

Explode Array to Rows: Using Snowflake Flatten Function & Lateral. The FLATTEN function is a table function that explores the values of an object or array object into rows. A lateral perspective is created by using the flatten function. When converting array data to table rows, the flatten function is most typically employed.

The result will be about 4 rows having the following structure: I need to convert the result into an array of object. I tried using: select array_construct(*) from my_table; But it transformed each row into an array with no keys like: [1, 'TEST', 2, 'DATA']. I am using a JavaScript procedure.

Ok, interesting. So the ::variant is indicating that there are other elements in the arrays as well? Would I have to explicitely declare what all they are such as in the statement array_construct('cats', 'dogs'))?That makes it difficult querying when different rows have arrays with different sets of elements that include 'cat' as well ["horses","cows","cats"] or just ["cat"] or for that matter ...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. ;Here is one way to do it. First get rid of the [" and ]" as the double quotes in city column don't enclose single array elements but all of them, then tokenize the string and return it as real array with strtok_to_array, then flatten the array elements to separate rows and lateral join the rows (cities) back to the rest of the record. with data as.Ok, interesting.

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:

1. I have a table column with nested arrays in a Snowflake database. I want to convert the nested array into columns in the manner shown below in Snowflake SQL. Table Name: SENSOR_DATA. The RX column is of data type VARIANT. The nested arrays will not always be 3 as shown below. There are cases where there are 20,000 nested arrays, and other ...

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.Using the docs mentioned by @Nat (Nanigans) and @mark.peters (Snowflake) here a way to do it.

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¶ Arguments. value_expr. 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. In most such cases, the data comes and sits in the database as an array or as an object. There could be some applications that will write this data as a string consisting of a set of values separated by commas. In such cases, it becomes necessary for the user to separate these values and store each value in a separate column.The result will be about 4 rows having the following structure: I need to convert the result into an array of object.
