Below is the data in *favorite_result (datatype: array<string>) *column.
Its an array of String in hive-

["CARS%20500%2E00","cars","VAN%2C%20Under%20£1%2C000%2E00%20Ending%20within%202%20days","COM%20VE","SNAP%20ON%20-LENS%20-BATTERY%20-BELT%20-PHONE%20-IPHONE","Under%20£100%2E00","","","",""]
How I can explode this above string in hive?

Basically How can I get each String outside, something like
*favorite_result [3]
should return *"VAN%2C%20Under%20£1%2C000%2E00%20Ending%20within%202%20days",

Hi Raihan

To fetch an element of an Array you can just specify the position of the element in your query.

Say if you have a table like
'test_table' with a field 'arr_clmn Array<STRING>', you can get the first element of the array as

SELECT arr_clmn[0] FROM test_table;

Or if you are looking at exploding the row itself to multiple rows you can do so with

SELECT * FROM test_table LATERAL VIEW explode(arr_clmn) exp_arr AS arr_elmnt;
