Use LEFT OUTER JOIN; something like:
SELECT Accounts.ID
,Accounts.Name
,Paddress.whatever
,Iaddress.whatever
FROM Accounts
LEFT OUTER JOIN Addesses Paddress
ON Accounts.Id=Paddress.AccountId
AND Paddress.IsPrimary=1
LEFT OUTER JOIN Addesses Iaddress
ON Accounts.Id=Iaddress.AccountId
AND Iaddress.Type='Invoice'

I knew it would be simple, I am learning, I promise.
Thanks for the quick response.

I have now inspected the sample SQL code you provided and have identified where I was failing. In short the AND clause of each of the LEFT OUTER JOIN. I was originally attempting to use a WHERE clause at the end of the SELECT.
Thanks again

I expect either would do, but I prefer to put it in ON in the (perhaps mistaken) belief that it is more efficient (in some cases).

They WHERE option would return a different result to the cluase on the JOIN. If I was filter on the WHERE then a Primary AND Invoice address would need to be present for a result to be returned. Your example will return a result even is there is not a Primary or Invoice address.

hi all
im converting a load of queries from MySQL to MSSQL and have run into a problem and was wondering if anyone had any ideas.....
I currently have:
SELECT 'PI' AS transaction_type, t1.supplier_code, t1.nominal_code, '01-01-2006' AS my_dispatch_date, t2.name AS resourcename, t2.reference, '1.20' AS royalty_amount,
t3.code, '1.21' AS tax_amount, '1' AS blank_field_2, '_' AS blank_field_3, '_' AS blank_field_4
FROM order_line AS t4 INNER JOIN
resource AS t2 ON t4.resource_id = t2.resource_id INNER JOIN
supplier_codes AS t1 ON t2.reference = t1.reference AND t4.dispatch_date >= t1.payment_start_date AND t4.dispatch_date <= t1.payment_end_date INNER JOIN
partners AS t5 ON t1.partner_id = t5.partner_id INNER JOIN
tax_codes AS t3 ON t5.tax_code = t3.id INNER JOIN
partner_type AS t6 ON t1.partner_type_id = t6.partner_type_id
WHERE (t4.status = 1) AND (t4.dm <> 'ZX') AND (t4.dispatch_date >= @from) AND (t4.dispatch_date <= @to)
ORDER BY t4.dispatch_date, t2.reference
but i need to group by t1.reference, t1.supplier_code but obviously it keeps telling me I can't do that, my brains a bit fried atm, if anyones got any great ideas it would be really helpful

To use group by, you need an aggregate... sum(...) or count(...) or avg(...), etc.

problem is...I dont want to do anything with them apart from get the values in the same way you do in MySQL, I just want to get rid of the duplicates that get pulled based on certain criteria.
this is what I'm converting:
SELECT
'PI' as transaction_type,
supplier_codes.supplier_code,
supplier_codes.nominal_code,
COUNT(o.orderline_id) as sale_volume,
IF ( EXTRACT(MONTH FROM STR_TO_DATE(CONCAT(YEARWEEK(dispatch_date),'0'),'%x%v%w')) = MONTH(dispatch_date),
DATE_FORMAT(STR_TO_DATE(CONCAT(YEARWEEK(dispatch_date),'0'),'%x%v%w'),'%d/%m/%Y'),
DATE_FORMAT(STR_TO_DATE(CONCAT('01/',EXTRACT(MONTH FROM dispatch_date),'/',YEAR(dispatch_date)),'%d/%m/%Y'),'%d/%m/%Y')) as my_dispatch_date,
resource.name as resourcename,
resource.reference,
SUM(supplier_codes.license_fee) as royalty_amount,
tax_codes.code,
ROUND(((SUM(supplier_codes.license_fee) / 100) * tax_codes.multiplier),2) as tax_amount,
"1" as blank_field_2,
"_" as blank_field_3,
"_" as blank_field_4
FROM order_line o
LEFT JOIN resource ON o.resource_id = resource.resource_id
LEFT JOIN supplier_codes ON resource.reference = supplier_codes.reference
LEFT JOIN partners ON supplier_codes.partner_id = partners.partner_id
LEFT JOIN partner_type ON supplier_codes.partner_type_id = partner_type.partner_type_id
LEFT JOIN tax_codes ON partners.tax_code = tax_codes.id
WHERE supplier_codes.payment_start_date <= dispatch_date
AND supplier_codes.payment_end_date >= dispatch_date
AND o.status = 1
AND DATE_FORMAT(o.dispatch_date,'%Y-%m-%d') >= '$from'
AND DATE_FORMAT(o.dispatch_date,'%Y-%m-%d') < '$to'
AND o.dm !='ZX'
GROUP BY reference, supplier_code, my_dispatch_date
ORDER BY dispatch_date, reference
dont worry about the difference in some of the vars in it, its only the group by thats doing my head in

Ok.... in SQLServer, a group by is used if there are any aggregate fields (sum, count, etc).
In your original query (from MySQL), there is a COUNT and 2 SUM aggregate fields.
If you want the sales volumne (COUNT), royalty amount (SUM) and tax amount (SUM) in your SQLServer query, GROUP BY any non-aggregate fields:
GROUP BY supplier_codes.supplier_code, supplier_codes.nominal_code, resource.name, resource.reference, tax_codes.code
The GROUP BY clause must go after the WHERE and before the ORDER BY
If you are currently getting duplicate records, change the SELECT to SELECT DISTINCT.
Hope that helps...

Hi,
I am looking to return all the rows where the OldReferenceNumber field is equal to the value of the parameter, currently it returns nothing, there are a couple of fields that are null:
DECLARE @OldReferenceNumber VARCHAR(50);
SET @OldReferenceNumber = NULL;
SELECT
OldReferenceNumber
FROM
Product
WHERE
OldReferenceNumber = @OldReferenceNumber;
Please can some one help me?
Thanks
Brendan

You cannot reference nulls with =
WHERE
coalesce(OldReferenceNumber,'') = coalesce(@OldReferenceNumber,'')

Thanks, this works just fine. I just need to modify it a little bit. Lets say the colum does not contain a NULL value, and maybe some text like Old Reference Number. I need this WHERE clause modified so that if the user types in old ref that it still returns the row. Normally I would use a LIKE with a '%' but I can not seem to get it to work here.
Thanks
Brendan

SET @OldReferenceNumber = NULL;
OldReferenceNumber = @OldReferenceNumber;
That won't work
|
|
|
|
|
SET @OldReferenceNumber = NULL;
OldReferenceNumber = @OldReferenceNumber;
That won't work, you need
OldReferenceNumber IS NULL
Or some "not exist" value
SET @OldReferenceNumber = -1;
ISNULL(OldReferenceNumber,-1) = @OldReferenceNumber;
|
|
|
|
|
Or as I said originally,
WHERE coalesce(OldReferenceNumber,'') = coalesce(@OldReferenceNumber,'')

Yeah, but that's ugly. 
|
|
|
|
|
Ugly but correct. Coalesce is the new ISNULL

Hi,
I have an application , which has a thread that checks the DB existance by opening a new connection.
When the open statement is executed when some dialog gets destroyed in the main thread of the application. The database open throws exception with the error "General error: invalid window handle".
What could be the reason for it?
Is there any solution to overcome it.

Hi,
I am 2 fields in my Product table, namely RandAmount and ForeignAmount. When they do a search, there is are 2 radio buttons given the user the option to search for rand amount or foreign amount. And then there is a texbox for the value. Here is my where clause which does not work, it must just work on 1 of the 2 fields, if @CurrencyInd is 1 then it searches on rand amount, and when it is 2 then it searches on foreign amount:
WHERE
p.RandAmount = (CASE @CurrencyInd WHEN 1 THEN @CurrenyAmount ELSE p.RandAmount END)
AND p.ForeignAmount = (CASE @CurrencyInd WHEN 2 THEN @CurrenyAmount ELSE p.ForeignAmount END)
I have also tried the following, but also does not help:
WHERE
CASE @CurrencyInd
WHEN 1 THEN (p.RandAmount = @CurrenyAmount)
WHEN 2 THEN (p.ForeignAmount = @CurrenyAmount)
END
Please can someone help?
Thanks
Brendan
