Error's pretty clear. When using a union, intersect or except all the queries must have the same number of columns

The term for this is "union compatible" and it means that both tables in a set operation have to have the same number of columns and those columns have to match by data type and by position.

Further more, the result of a set operation is a table whose columns have no names. This means that you need to write an AS clause to name them.

(<table expr #1>
[UNION | INTERSECT | EXCEPT] [ALL]
<table expr #2>)
[AS] <table name> (<column list>)

No you don't for SQL Server. The first query provides all the column names.

If all the queries in combined by the UNION statement are quering the same table (or differenet tables but the coumn names are the same), then you shoudn't need to use AS <header>, correct?

You don't need the AS header in SQL Server at all. SQL gets the result column names from the first query in a UNION. The others can have different column names -- or no column names at all.


SELECT 1 AS a, 2 AS b
union all
select 3 as c, 4 as d
union all
select 5 as e, 6 as f 
union all
select 7, 8
