Hive 在导出 csv 时抛出 ParseException

Question

hive -e 'SELECT *, MIN(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS MIN_YEARLY, MAX(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS MAX_YEARLY, AVG(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS AVG_YEARLY, STDDEV(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS STD_YEARLY FROM NSEDATA ORDER BY SYMBOL;' | sed 's/[[:space:]]\+/,/g' > ~/output2.csv

运行 这段代码，我正在尝试导出 csv 但出现以下错误：

ParseException line 2:3 cannot recognize input near 'MIN' '(' 'HIGH' in expression specification

Answer 1

尝试添加 table 别名 (d) 并使用 select d.* 而不是 select *：

hive -e "SELECT d.*, 
MIN(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS MIN_YEARLY, 
MAX(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS MAX_YEARLY, 
AVG(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS AVG_YEARLY, 
STDDEV(HIGH) OVER(PARTITION BY SYMBOL ORDER BY TIMESTAMP) AS STD_YEARLY 
FROM NSEDATA d 
ORDER BY SYMBOL" | sed 's/[[:space:]]\+/,/g' > ~/output2.csv
