SQL Statement to pull records from multiple tables - mysql

Question

I've trying to pull contacts from my email server's SQL database.
Need to pull the User, the Contact, and all the contacts details.
However, everything is in a separate table.
This is what i'm running:
SELECT [Contacts].[ID]
,[Users].[LoginName]
,[Contacts].[JobTitle]
,[Contacts].[Company]
,[Contacts].[WebPageAddress]
,[Contacts].[FirstName]
,[Contacts].[LastName]
,[EmailAddresses].[Address]
,[EmailAddresses].[Name]
,[Addresses].[Name]
,[Addresses].[Address1]
,[Addresses].[Town]
,[Addresses].[County]
,[Addresses].[Country]
,[Addresses].[Postcode]
,[PhoneNumbers].[Name]
,[PhoneNumbers].[Number]
FROM [WorkgroupShare].[dbo].[Contacts]
INNER JOIN [WorkgroupShare].[dbo].[Users]
ON [WorkgroupShare].[dbo].[Contacts].[Owner]=[WorkgroupShare].[dbo].[Users].[ID]
FULL OUTER JOIN [WorkgroupShare].[dbo].[EmailAddresses]
ON [WorkgroupShare].[dbo].[Contacts].[ID]= [WorkgroupShare].[dbo].[EmailAddresses].[OwnerID]
FULL OUTER JOIN [WorkgroupShare].[dbo].[Addresses]
ON [WorkgroupShare].[dbo].[Contacts].[ID]= [WorkgroupShare].[dbo].[Addresses].[OwnerID]
FULL OUTER JOIN [WorkgroupShare].[dbo].[PhoneNumbers]
ON [WorkgroupShare].[dbo].[Contacts].[ID]= [WorkgroupShare].[dbo].[PhoneNumbers].[OwnerID]
order by [Contacts].[ID]
Since the Name field in the EmailAddress.Name contains either Email1 or Email2 I get a double return for each record. And the Address.Name field contains business, home or other I get a triple. and the PhoneNumbers.Name contains 4 field I get quadruple. Then you multiple that together an a list of 6000 contacts turns into several tens of thousands. Can't figure out how to write a loop or while statement. I think I have the logic just can't figure out the syntax. Any help would be greatly appreciated.

If you have a fixed set of values in each of the Name fields, then you can hard-code them into columns, so you get 1 row per contact with columns representing each 'flavour' of reference data. Something like below (I haven't added it for the 4 phone numbers as you didn't supply the possible values for Name in that case, but you should be able to get the drift):
SELECT [Contacts].[ID]
,[Users].[LoginName]
,[Contacts].[JobTitle]
,[Contacts].[Company]
,[Contacts].[WebPageAddress]
,[Contacts].[FirstName]
,[Contacts].[LastName]
,email1.[Address] as email1Address
,email2.[Address] as email2Address
,Address1.[Address1] as HomeAddress1
,Address1.[Town] as HomeAddressTown
,Address1.[County] as HomeAddressCounty
,Address1.[Country] as HomeAddressCountry
,Address1.[Postcode] as HomeAddressPostcode
,Address2.[Address1] as BusinessAddress1
,Address2.[Town] as BusinessAddressTown
,Address2.[County] as BusinessAddressCounty
,Address2.[Country] as BusinessAddressCountry
,Address2.[Postcode] as BusinessAddressPostcode
,Address3.[Address1] as OtherAddress1
,Address3.[Town] as OtherAddressTown
,Address3.[County] as OtherAddressCounty
,Address3.[Country] as OtherAddressCountry
,Address3.[Postcode] as OtherAddressPostcode
,[PhoneNumbers].[Name]
,[PhoneNumbers].[Number]
FROM [WorkgroupShare].[dbo].[Contacts]
INNER JOIN [WorkgroupShare].[dbo].[Users]
ON [WorkgroupShare].[dbo].[Contacts].[Owner]=[WorkgroupShare].[dbo].[Users].[ID]
FULL OUTER JOIN [WorkgroupShare].[dbo].[EmailAddresses] email1
ON [WorkgroupShare].[dbo].[Contacts].[ID]= email1.[OwnerID] AND email1.[Name] = 'Email1'
FULL OUTER JOIN [WorkgroupShare].[dbo].[EmailAddresses] email2
ON [WorkgroupShare].[dbo].[Contacts].[ID]= email1.[OwnerID] AND email1.[Name] = 'Email2'
FULL OUTER JOIN [WorkgroupShare].[dbo].[Addresses] Address1
ON [WorkgroupShare].[dbo].[Contacts].[ID]= Address1.[OwnerID] AND Address1.Name = 'Home'
FULL OUTER JOIN [WorkgroupShare].[dbo].[Addresses] Address2
ON [WorkgroupShare].[dbo].[Contacts].[ID]= Address2.[OwnerID] AND Address2.Name = 'Business'
FULL OUTER JOIN [WorkgroupShare].[dbo].[Addresses] Address3
ON [WorkgroupShare].[dbo].[Contacts].[ID]= Address3.[OwnerID] AND Address3.Name = 'Other'
FULL OUTER JOIN [WorkgroupShare].[dbo].[PhoneNumbers]
ON [WorkgroupShare].[dbo].[Contacts].[ID]= [WorkgroupShare].[dbo].[PhoneNumbers].[OwnerID]
order by [Contacts].[ID]
