https://community.qlik.com/t5/Talend-Studio/An-object-or-column-name-is-missing-or-empty-SqlServer/m-p/2206237#M6381 Hi when i try to do the ETL PRocess i get this : <BR />An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name. <BR />this is the Query that i use : <BR />select distinct(FechaEmision) as fecha, MONTH(FechaEmision) as mes, YEAR(FechaEmision) as año from ReciboCompra <BR />i use the Version: 5.3.0 <BR />Thanks !

I would avoid using language specific characters and write as alias in this case ano even it sounds not pretty in Spanish (?)
