SQL Query Help - searching on multiple 'pairs' or data - sql-server

Question

I'm struggling to work out how to do a SQL query on a database that I have.
I have a view (which can be changed) which shows the relationships between the tables.
This creates a view as follows:
What I need to be able to do is search on one or more 'Attribute Pairs'
for example
I want to search for records with:
(
(AttributeName='FileExtension' AND AttributeValue='.pdf')
AND (AttributeName='AccountNumber' AND AttributeValue='ABB001'
)
As you can tell, this is not working as AttributeName cant be two things at once. I have this working with an OR filter, but I want it to find records that have all attribute pairs
SELECT
dbo.SiconDMSDocument.SiconDMSDocumentID,
dbo.SiconDMSAttribute.SiconDMSAttributeID,
dbo.SiconDMSAttribute.AttributeFriendlyName,
dbo.SiconDMSAttribute.AttributeName,
dbo.SiconDMSDocumentAttribute.AttributeValue,
dbo.SiconDMSAttribute.DataType,
dbo.SiconDMSDocumentType.SiconDMSDocumentTypeID,
dbo.SiconDMSDocumentType.DocumentTypeName,
dbo.SiconDMSDocumentType.DocumentTypeFriendlyName,
dbo.SiconDMSModule.SiconDMSModuleID,
dbo.SiconDMSModule.ModuleName,
dbo.SiconDMSModule.ModuleFriendlyName,
dbo.SiconDMSDocument.SiconDMSDocumentTypeModuleID
FROM dbo.SiconDMSDocument
INNER JOIN dbo.SiconDMSDocumentAttribute ON dbo.SiconDMSDocument.SiconDMSDocumentID = dbo.SiconDMSDocumentAttribute.SiconDMSDocumentID
INNER JOIN dbo.SiconDMSAttribute ON dbo.SiconDMSDocumentAttribute.SiconDMSAttributeID = dbo.SiconDMSAttribute.SiconDMSAttributeID
AND
(
(dbo.SiconDMSAttribute.AttributeName = 'Reference' AND dbo.SiconDMSDocumentAttribute.AttributeValue='12345')
OR (dbo.SiconDMSAttribute.AttributeName = 'AccountNumber' AND dbo.SiconDMSDocumentAttribute.AttributeValue='ABB001')
)
INNER JOIN dbo.SiconDMSDocumentTypeModule ON dbo.SiconDMSDocument.SiconDMSDocumentTypeModuleID = dbo.SiconDMSDocumentTypeModule.SiconDMSDocumentTypeModuleID
INNER JOIN dbo.SiconDMSDocumentType ON dbo.SiconDMSDocumentTypeModule.SiconDMSDocumentTypeID = dbo.SiconDMSDocumentType.SiconDMSDocumentTypeID
INNER JOIN dbo.SiconDMSModule ON dbo.SiconDMSDocumentTypeModule.SiconDMSModuleID = dbo.SiconDMSModule.SiconDMSModuleID
WHERE
(dbo.SiconDMSDocument.Deleted = 0)
AND (dbo.SiconDMSDocumentAttribute.Deleted = 0)
AND (dbo.SiconDMSAttribute.Deleted = 0)
AND (dbo.SiconDMSDocumentType.Deleted = 0)
AND (dbo.SiconDMSDocumentTypeModule.Deleted = 0)
AND (dbo.SiconDMSModule.Deleted = 0)
Are there any SQL functions that will allow me to do something like this?

I'm not sure what your complicated query has to do with the question of searching for attribute pairs.
Assuming you want the document ids that have both attributes:
select SiconDMSDocumentID
from yourview y
where (AttributeName = 'FileExtension' AND AttributeValue = '.pdf') or
(AttributeName = 'AccountNumber' AND AttributeValue = 'ABB001'
group by SiconDMSDocumentID
having count(*) = 2;
Or, if the attributes could have multiple values:
having count(distinct AttributeName) = 2
