Colmena: SELECT AS y GROUP BY

Question

tengo una colmena consulta como

SELECT Year, Month, Day, Hours, Minutes, 
      cast((cast(Seconds as int)/15) as int)*15 
AS secondMod, Count(*) AS PerCount FROM LoggerTable 
GROUP BY Year, Month, Day, Hours, Minutes, secondMod 
ORDER BY PerCount; 

la consulta anterior falla con un error

FAILED: Error in semantic analysis: line 1:175 Invalid Table Alias or Column Reference secondMod

'LoggerTable' es una tabla de la colmena con todas las columnas de tipo de cadena .

¿Alguna solución para este problema?

Answer 1

Prueba esto:

SELECT Year, Month, Day, Hours, Minutes, 
cast((cast(Seconds as int)/15) as int)*15 
AS secondMod, Count(*) AS PerCount FROM LoggerTable 
GROUP BY Year, Month, Day, Hours, Minutes, 
    cast((cast(Seconds as int)/15) as int)*15 
ORDER BY PerCount; 

Answer 2

En Colmena 0.11.0 y más tarde, las columnas se puede especificar si la posición hive.groupby.orderby.position.alias se establece en true. Confirme si la siguiente consulta funciona para usted.

SET hive.groupby.orderby.position.alias=true; 
SELECT Year 
     ,Month 
     ,Day 
     ,Hours 
     ,Minutes 
     ,cast((cast(Seconds as int)/15) as int)*15 AS secondMod 
     ,count(*) AS PerCount 
FROM LoggerTable 
GROUP BY 1, 2, 3, 4, 5, 6 
ORDER BY 7;
