Question

dizisinde Array literal

Hive'da bir dizi hazır kelimesini nasıl yazarım?

SELECT PERCENTILE(my_column, [0.5, 0.25, 0.50, 0.75, 0.95]) AS quantiles 
FROM my_table 

FAILED: ParseException line xx:xx cannot recognize input near '[' '0.5' ',' in select expression 

Answer 1

array kullanmayı deneyin yerine https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF uyarınca []

SELECT PERCENTILE(my_column, array(0.5, 0.25, 0.50, 0.75, 0.95)) AS quantiles 
FROM my_table
