To build on Lynn's point, if you don't have data for the second query, you can put in blank scalars like this:

select

SabtHazineID,

SabtHazine.HazineID,

EndUserNAme,

Tedad,

sabtHazineDate,

Describtion

from

dbo.SabtHazine

left JOIN dbo.Hazine

ON dbo.Hazine.HazineID = dbo.SabtHazine.HazineID

union all

select

Hazine.HazineName,

Hazine.Mablagh,

'',

'',

'',

'',

from

AgencyDB.dbo.Hazine

where

HazineID not in (select HazineID from dbo.Hazine);
