BigQuery: SPLIT() returns only one value

Question

I have a page URL column components of which are delimited by /. I tried to run the SPLIT() function in BigQuery but it only gives the first value.

Answer 1

in standard sql, you can use the following functions:

array[OFFSET(zero_based_offset)]
array[ORDINAL(one_based_ordinal)]

so

SELECT SPLIT(path, '/')[OFFSET(1)] part2,
       SPLIT(path, '/')[ORDINAL(2)] part2_again,
       SPLIT(path, '/')[ORDINAL(3)] part3
FROM (SELECT "/a/b/aaaa?c" path)

part2   part2_again part3    
a       a           b

part1 in this case, is empty string (before the first slash)
