Typically, if the input contained zero ...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.CREATE OR REPLACE TABLE to_variant_example (v_varchar VARIANT, v_number VARIANT, v_timestamp VARIANT, v_array VARIANT, v_object VARIANT); INSERT INTO to_variant_example (v_varchar, v_number, v_timestamp, v_array, v_object) SELECT TO_VARIANT ('Skiing is fun!'To iterate through the array and expand individual values, we need to flatten it. This will result in three individual rows, each containing a single value from the array. Snowflake offers two functions for this purpose: LATERAL and FLATTEN, which are often used together.As you noticed yourself, you want 4 records. There are 2 ways to do it, both exploit the index column produced by flatten, which represents the position of the produced value in the input (see the Flatten Documentation). Using 2 flattens and index-selection.

The source array. A (zero-based) position in the source array. The new element is inserted at this position. The original element from this position (if any) and all subsequent elements (if any) are shifted by one position to the right in the resulting array (i.e. inserting at position 0 has the same effect as using ARRAY_PREPEND ).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.select. json[0]:lfd as lfd. ,to_timestamp_ntz(lfd) as lfd_as_timestamp. from fake_data; Now if you are not always sure the order of you array, or you need to pick an array element, you will want to FLATTEN the array.

About undesired object_agg() deduplication: good point. Normally in this case it would be nice to use a json array and collect each k:v pair into an element, but this doesn't seem to be an option here. –1. Using snowflake, I have a column named 'column_1'. The datatype is TEXT. I say: select to_array(column_1) from fake_table; and I get: So it put my text into it. But I want to convert the datatype. Seems like it should be simple. I try strtok_to_array(column_1, ',') and get the same situation.6. Use FLATTEN. It has various options, including things like the value of the field, but also index in the array etc. A full example below: create or replace table x(i int, s string, v variant); insert into x. select column1, column2, parse_json(column3) from values. (1, 'ts1', '[1,2,3]'), (2,'ts2','[7,8,9]');
