Hi -
I am a newbie to t-sql and have an issue that I am not sure is me or sql
I want to merge several tables from several databases.
I have created a union statement:

create view myViewas
select *, ‘1’ as compId, ‘AAA’ as SiteID from ClientAAA.dbo.stats
UNION
(select *, ‘2’ as compID, ‘ABC’ as SiteID from clientABC.dbo.stats
UNION
(select *, ‘3’ as compID, ‘ABD’ as SiteID from clientABD.dbo.stats
UNION
(select *, ‘4’ as compID, ‘ABF’ as SiteID from clientABF.dbo.stats
UNION
(select *, ‘5’ as compID, ‘AGG’ as SiteID from clientAGG.dbo.stats
))))
Its ok till the last statement then they repeat from the 4th line stats.
Any help would be great

Of course!

You add a unique value for each record in same table so that they cannot be distinct (union) with data from other tables.

SELECT	*,
	'1' AS CompID,
	'AAA' AS SiteID
FROM	ClientAAA.dbo.Stats

UNION

SELECT	*,
	'2' AS CompID,
	'ABC' AS SiteID
FROM	ClientABC.dbo.Stats

UNION

SELECT	*,
	'3' AS CompID,
	'ABD' AS SiteID
FROM	ClientABD.dbo.Stats

UNION

SELECT	*,
	'4' AS CompID,
	'ABF' AS SiteID
FROM	ClientABF.dbo.Stats

UNION

SELECT	*,
	'5' AS CompID,
	'AGG' AS SiteID
FROM	ClientAGG.dbo.Stats
