обр "[1,2,3,4,5,6,7]"
2. If an empty delimiter is specified, the function will return a UTF-8 characters array from the string value. We are splitting the string with the простір which acts as the delimiter в цьому випадку.
Приклад: (Array of strings)
ВИБІР SPLIT('p q r s t u v', ' ') AS arr;

обр "[p,q,r,s,t,u,v]"
3. Also, if you run an порожній рядок, the function will give an output with the empty array.
