配置单元在导出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

运行此代码，我正在尝试导出一个csv，但出现以下错误：

ParseException第2：3行无法识别表达式规范中'MIN''（'''HIGH'附近的输入

Answer 1

尝试添加表别名（d），并使用select d.*代替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
