I want to reproduce this output using FOR XML:
<Gear id='1'>
<materials>
<material>
<id>1</id>
<material_name> Leather </material_name>
</material>
<material>
<id>2</id>
<material_name> Bar</material_name>
</material>
</materials>
<category>
<id>1</id>
<name>Warriors Weapon</name>
</category>
<equipment>
<id> 1</id>
<equipment_name> Claymore </equipment_name>
<category> 1</category>
</equipment>
<recipes>
<recipe>
<equipment_id> 1 </equipment_id>
<material_id>1</material_id>
<material_quantity>12</material_quantity>
</recipe>
<recipe>
<equipment_id> 1 </equipment_id>
<material_id>2</material_id>
<material_quantity>20</material_quantity>
</recipe>
</recipes>
</Gear>
I got this far with my query:
select mat.id, mat.material_name , c.id, c.name, e.equipment_name, e.category_id, r.equipment_id, r.material_id, r.material_quantity
from Recipe as r
inner join Equipment as e on r.equipment_id = e.id
inner join Categories as c on c.id = e.category_id
inner join Materials as mat on r.material_id = mat.id
for xml Auto, Root('Gear'), Elements
and got this output:
<Gear>
<Materials>
<id>1</id>
<material_name>Bar</material_name>

And version is: Microsoft SQL Server 2019 (RTM) - 15.0.2000.5 (X64)
The idea, as you can see in the first example is to 'isolate' the diferents tables (Materials
, Equipment
, Categories
) and have all the records of the table Recipe
as part of the Gear
tag.
Can someone help me figure what im doing wrong?

Please try the following solution.
I am not sure about the relationships between tables.
You may need to adjust the WHERE
clauses...
