Question on results from Table Joins.

Hi there - i am relatively new to SQL server so please bear with me. I
am attempting to join several tables so that I can generate an asset
report. The query I am runnins is
-- Start of Main Select Query
select t_humanresources.fname as 'First Name',
t_humanresources.lname as 'Last Name',
t_humanresources.hridentifier1 as 'HR Identifier',
t_humanresources.locationid1 as 'Location'
--t_catalogs.model as 'Catalog Item Name',
--t_catalogs.manufacturerproductcode
from T_Catalogs
inner join t_assets
on t_catalogs.t_catalog_id = t_assets.t_catalog_id
inner join t_Teamresponsible_LUT
on t_assets.t_teamresponsible_id =
t_teamresponsible_lut.t_teamresponsible_id
inner join t_internallocations
on t_assets.t_internallocation_id =
t_internallocations.t_internallocation_id
inner join t_activedescriptions_LUT
on t_assets.t_activedescription_id =
t_activedescriptions_LUT.t_activedescription_id
inner join t_category_lut
on t_assets.t_category_id = t_category_lut.t_category_id
inner join t_assetusers
on t_assets.t_asset_id = t_assetusers.t_asset_id
inner join t_humanresources
on t_assetusers.t_hr_id = t_humanresources.t_hr_id
where t_humanresources.Lname = 'Capp'
My problem is when I run the above query I am getting multiple returns
against the particular surname even though there is only 1 person with
the surname in the particular t_humanresources table. The same is
happening for other fields i have listed as well (although I have
commented these out above).
Does anyone have any ideas as to why this is happening as all I want to
see is a list of Users and the particular hardware assigned to them.
Thanks

Can't users have more than one piece of hardware assigned to them?

Hi Ronnie,
In this query, you are joining to several tables that are not used. If
one row from your data matches several rows in those unused tables, the
row will appear to be duplicated - each occurence of the "duplicated"
row is linked to another row in the other table, but you can't see that
because those values are not displayed.
Try what happens if you remove the unused tables:
-- Start of Main Select Query
select t_humanresources.fname as 'First Name',
t_humanresources.lname as 'Last Name',
t_humanresources.hridentifier1 as 'HR Identifier',
t_humanresources.locationid1 as 'Location',
t_catalogs.model as 'Catalog Item Name',
t_catalogs.manufacturerproductcode
from T_Catalogs
inner join t_assets
on t_catalogs.t_catalog_id = t_assets.t_catalog_id
inner join t_assetusers
on t_assets.t_asset_id = t_assetusers.t_asset_id
inner join t_humanresources
on t_assetusers.t_hr_id = t_humanresources.t_hr_id
where t_humanresources.Lname = 'Capp'
And if you comment the two columns you take from t_catalogs, then you
should remove that table from the FROM clause as well.
If the above doesn't help, then see www.aspfaq.com/5006.

Hi Perayu,
How would a left join help to remove unwanted duplicates from the
results of the query?
I do see how it might return even more unwanted rows. And how it would
lower performance. But removing duplicates?
