Snowflake array length
The .size () function is available in Jquery and many other libraries. The .length property works only when the index is an integer. The length property will work with this type of array: var nums = new Array (); nums [0] = 1; nums [1] = 2; print (nums.length); // displays 2.Why array_length can find non-empty arrays but it doesn't work for empty arrays? postgresql; array; Share.

from test_array, lateral flatten (input => my_array); The documentation for ARRAY_AGG() doesn't mention any size restrictions, so I wonder if you are hitting the max size of Semi-structured Data Types which is 16MB compressed, or maybe even 16MB uncompressed since you are restructuring your ARRAY.Characteristics of a VARIANT A VARIANT can store a value of any other type, including OBJECT and ARRAY. The maximum length of a VARIANT is 16 MB. Using Values in a VARIANT To convert a value to or from the VARIANT data type, you can explicitly cast using the CAST function, the TO_VARIANT function or the :: operator (e.g. expression::variant ).Here we make use of some of the cool array functions in Snowflake, pushing all the distinct values into an array with array_agg so that we can use the array_position function to encode the label ...If you’re planning an event or gathering and want to treat your guests to an authentic Italian dining experience, look no further than Olive Garden’s catering menu.

As you've discovered, there is a hard limit of 16Mb on array_agg (and in a lot of other places in Snowflake e.g. it's the max size for a variant column). If it is acceptable to create multiple files then you can probably achieve this in a Stored Proc - find some combination of column values that will guarantee that the data in ...Snowflake SPLIT Function. The SPLIT function splits a given string with a given separator and returns the result in an array of strings. Following is the SPLIT function syntax.
