Question

I want to retrieve latest records of two tables using UNION, it returns data, but not latest records, even with ORDER BY. It’s my query:

    SELECT TOP(1) OwnerID,NewsTitle,NewsCreationDate,NewsTitle,NewsEnglishName 
FROM TheaterNews 
    UNION
    SELECT TOP(3) OwnerID,NewsTitle,NewsCreationDate,NewsTitle,NewsEnglishName  
FROM MoviesNews
    ORDER BY 3 DESC

This is query’s output:

But the latest record of TheaterNews is newer:

SELECT  OwnerID,NewsTitle,NewsCreationDate,NewsTitle,NewsEnglishName 
FROM TheaterNews 
ORDER BY NewsCreationDate DESC

How can I fix this? even with another method.

Answer 1

This should work in your instance. Might be a rough solution but you will get your answers. you can replace the #tables with @tables.

SELECT TOP(1) 
    OwnerID,
    NewsTitle,
    NewsCreationDate,
    NewsEnglishName 
into
    #Table1
FROM 
    TheaterNews 
ORDER BY 3 DESC

SELECT TOP(3) 
    OwnerID,
    NewsTitle,
    NewsCreationDate,
    NewsEnglishName
into
    #Table2
FROM 
    MoviesNews
ORDER BY 3 DESC

select * from #Table1
union
select * from #Table2

drop table #Table1
drop table #Table2
