How can I format a Mailing Address so that I always push all non-null rows to the top? That is, I want to convert an address from the structure below to a mailing address.
Here is the structure:
[Line1] [varchar](50) NULL,
[Line2] [varchar](50) NULL,
[Line3] [varchar](50) NULL,
[City] [varchar](50) NULL,
[State] [varchar] (2) NULL,
[PostalCode] [varchar](50) NULL,
Here is some sample data:
Line1=
Line2=123 Some Address
Line3=
City=Royal Oak
State=MI
ZIP=45673-2312
Here is what the result should look like (4 distinct or separate fields should be returned):
MailAddress1=123 Some Address
MailAddress2=ROYAL OAK MI 45673-2312
MailAddress3=
MailAddress4=
I am using SQL Server 2005.
Someone wrote this logic in our company and it just seemed to complex (Note: this is not the whole SELECT statement):
,CASE
WHEN eai.Line1 IS NULL OR eai.Line1 = '' THEN
CASE
WHEN eai.Line2 IS NULL OR eai.Line2 = '' THEN
CASE
WHEN eai.Line3 IS NULL OR eai.Line3 = '' THEN ISNULL(LTRIM(RTRIM(eai.City)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.PostalCode)),'')
ELSE eai.Line3
END
ELSE eai.Line2
END
ELSE eai.Line1
END
,CASE
WHEN eai.Line1 IS NULL OR eai.Line1 = '' THEN
CASE
WHEN eai.Line3 IS NULL OR eai.Line3 = '' THEN ISNULL(LTRIM(RTRIM(eai.City)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.PostalCode)),'')
ELSE eai.Line3
END
ELSE
CASE
WHEN eai.Line2 IS NULL OR eai.Line2 = '' THEN
CASE
WHEN eai.Line3 IS NULL OR eai.Line3 = '' THEN ISNULL(LTRIM(RTRIM(eai.City)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.PostalCode)),'')
ELSE eai.Line3
END
ELSE eai.Line2
END
END
,CASE
WHEN eai.Line1 IS NULL OR eai.Line1 = '' THEN
CASE
WHEN eai.Line2 IS NULL OR eai.Line2 = '' THEN NULL
ELSE
CASE
WHEN eai.Line3 IS NULL OR eai.Line3 = '' THEN NULL
ELSE ISNULL(LTRIM(RTRIM(eai.City)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.PostalCode)),'')
END
END
ELSE
CASE
WHEN eai.Line2 IS NULL OR eai.Line2 = '' THEN
CASE
WHEN eai.Line3 IS NULL OR eai.Line3 = '' THEN NULL
ELSE ISNULL(LTRIM(RTRIM(eai.City)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.PostalCode)),'')
END
ELSE
CASE
WHEN eai.Line3 IS NULL OR eai.Line3 = '' THEN ISNULL(LTRIM(RTRIM(eai.City)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(eai.PostalCode)),'')
ELSE eai.Line3
END
END
END
,CASE WHEN eai.Line2 IS NOT NULL AND eai.Line2 <> '' AND eai.Line3 IS NOT NULL AND eai.Line3 <> '' THEN eai.City + ' ' + eai.RegionCode + ' ' + eai.PostalCode ELSE NULL END
The way to do this is with an UNPIVOT. Here is the solution:
With AddrTable as (
Select AddrFld, MailAddr From (
Select Cast(ISNULL([Line1], '') as Varchar(102)) as [A1],
Cast(ISNULL([Line2], '') as Varchar(102)) as [A2],
Cast(ISNULL([Line3], '') as Varchar(102)) as [A3],
Cast(ISNULL(LTRIM(RTRIM(City)),'') + ' ' + ISNULL(LTRIM(RTRIM(RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(PostalCode)),'') as Varchar(102)) as A4
From TableName Where UniqueID=#UniqueID) p
Unpivot (MailAddr For AddrFld in ([A1], [A2], [A3], [A4])) as unpvt)
Select Row_Number() over (Order by (Case Len(MailAddr) When 0 then 1 else 0 end), AddrFld) as RN,
MailAddr From AddrTable
Order By RN
Here's the output:
Address1
Westby WI 55555
-empty line-
-empty line-
Note that I had to use "Varchar(102)" as the field length (unpivot requires that all fields be the same) because your City/Region/Postal can have up to 102 chars in total. Also, note that "#UniqueID" is the identifier for the record whose address you need. This returns four and always four rows containing the data you need for your address.
UPDATE: If you need to return this as a set of four columns rather than four rows, then just plop it into a view and then query the view with a Pivot. I've included the view here for completeness as I had to change the above just a bit when creating the view so the uniqueID field was included and no sort was done (the sort is now done in the query):
Create View AddressRows AS
With AddrTable as (
Select UniqueID, AddrFld, MailAddr From (
Select UniqueID,
Cast(ISNULL([Line1], '') as Varchar(102)) as [A1],
Cast(ISNULL([Line2], '') as Varchar(102)) as [A2],
Cast(ISNULL([Line3], '') as Varchar(102)) as [A3],
Cast(ISNULL(LTRIM(RTRIM(City)),'') + ' ' + ISNULL(LTRIM(RTRIM(RegionCode)),'') + ' ' + ISNULL(LTRIM(RTRIM(PostalCode)),'') as Varchar(102)) as A4
From TableName Where UniqueID=#UniqueID) p
Unpivot (MailAddr For AddrFld in ([A1], [A2], [A3], [A4])) as unpvt)
Select UniqueID,
Row_Number() over (Order by (Case Len(MailAddr) When 0 then 1 else 0 end), AddrFld) as RN,
MailAddr From AddrTable
And then, when you want to pull your matching "row" out, Pivot it back using this SQL (notice that I am querying again using UniqueID):
Select [Addr1], [Addr2], [Addr3], [Addr4] From (
Select Top 4 'Addr' + Cast(Row_Number() over (Order by RN) as Varchar(12)) as AddrCol, -- "Top 4" needed so we can sneak the "Order By" in
MailAddr
From AddressRows Where UniqueID=#UniqueID
) p PIVOT (Max([MailAddr]) for AddrCol in ([Addr1], [Addr2], [Addr3], [Addr4])
) as pvt
This returns:
Addr1 Addr2 Addr3 Addr4
-------------- ------------------ ------------- ------------------
Address1 Westby WI 54667
Here's a three-minutes-invested solution:
DECLARE #address TABLE (
[Line1] [varchar](50) NULL,
[Line2] [varchar](50) NULL,
[Line3] [varchar](50) NULL,
[City] [varchar](50) NULL,
[State] [varchar] (2) NULL,
[PostalCode] [varchar](50) NULL
)
INSERT INTO #address (
[Line1],
[Line2],
[Line3],
[City],
[State],
[PostalCode]
)
VALUES (
NULL,
'123 Some Address',
NULL,
'Royal Oak',
'MI',
'45673-2312'
)
SELECT * FROM #address
SELECT
ISNULL(Line1 + CHAR(13), '')
+ ISNULL(Line2 + CHAR(13), '')
+ ISNULL(Line3 + CHAR(13), '')
+ ISNULL(City + ' ', '')
+ ISNULL([State] + ' ', '')
+ ISNULL(PostalCode, '')
FROM #address
Result:
123 Some Address

Fiddle with the control characters until you get the result you need.

You need to use the TYPE key word to enforce the characters to be retained, and then extract the value of your text in the generated XML instead using value:
DECLARE #Body nvarchar(MAX);
SELECT #Body = STUFF((SELECT ', ' + CASE
WHEN A.splitFlag = 1

ELSE QUOTENAME(A.DKFeatureName)
END

I'm trying to compare some data from different multiple databases, as I have illustrate my current case, I have there databases, database 1 is the main, and time to time database 2 and database 3 are updated from database 1. I have some difficulties to get the final result which return the data from database 1 and two columns column show the availability in database 2 as Yes or No, and the same with second extra column that will indicate the data availability on the database 3 with Yes or NO.

Use this as your first select statement:

,CASE WHEN DB2_VIEW.db2_ID IS NOT NULL THEN 'Y' ELSE 'N' END AS Available_db2
,CASE WHEN DB3_VIEW.db3_ID IS NOT NULL THEN 'Y' ELSE 'N' END AS Available_db3
You can remove all the details apart from the ID fields in the db2_view and db3_view subqueries.

How do i use the LTRIM & RTRIM with the following SQL? I need to LTRIM and RTRIM all these fields for leading spaces
UPDATE CORE.WeccoPartyAddress
SET AddressElements = CONTROL.TrimChar(
CASE when COALESCE(Address1,'') != '' THEN Address1 + ', ' ELSE '' END +
CASE when COALESCE(Address2,'') != '' THEN Address2 + ', ' ELSE '' END +
CASE when COALESCE(Address3,'') != '' THEN Address3 + ', ' ELSE '' END +
CASE when COALESCE(Town,'') != '' THEN Town + ', ' ELSE '' END +
CASE when COALESCE(County,'') != '' THEN County + ', ' ELSE '' END +
CASE when COALESCE(Postcode,'') != '' THEN Postcode ELSE '' END, ', '
)
Use like below nested:
UPDATE CORE.WeccoPartyAddress SET AddressElements = rtrim(ltrim(CASE when COALESCE(Address1,'') != '' THEN Address1 + ', ' ELSE '' END + CASE when COALESCE(Address2,'') != '' THEN Address2 + ', ' ELSE '' END + CASE when COALESCE(Address3,'') != '' THEN Address3 + ', ' ELSE '' END + CASE when COALESCE(Town,'') != '' THEN Town + ', ' ELSE '' END + CASE when COALESCE(County,'') != '' THEN County + ', ' ELSE '' END + CASE when COALESCE(Postcode,'') != '' THEN Postcode ELSE '' END))
You don't have to use CASE in your statement
UPDATE CORE.WeccoPartyAddress
SET AddressElements = ISNULL( STUFF (
COALESCE( ', ' + LTRIM( RTRIM(Address1) ) , '') +
COALESCE( ', ' + LTRIM( RTRIM(Address1Address2) ) , '') +
COALESCE( ', ' + LTRIM( RTRIM(Address1Address3) ) , '') +
COALESCE( ', ' + LTRIM( RTRIM(Address1Town) ) , '') +
COALESCE( ', ' + LTRIM( RTRIM(Address1County) ) , '') +
COALESCE( ', ' + LTRIM( RTRIM(Address1Postcode) ) , '')
,1
,2
,''
), '')
If any of Address values is not null you will get string like this: ', Address', then using the function STUFF you replace ', ' at the beginning of the string to get 'Address' as the result.
If all values are null the STUFF function will return NULL which will be replaced with '' by ISNULL function.
Have a 5 columns of address data. I need to concatenate these fields into a single address with spaces in between the values if they exist. If the column has a null value I should skip it and not enter any space.
select
case
when street_number != '' THEN (cast(street_number as int))
end as street_number,
case
when street_ext != '' then
case
when street_ext = 50 then '1/2'
end
end as street_ext,
case
when street_direct ! = '' then street_direct
end as street_direct,
case
when site_street ! = '' then site_street
end as site_street,
case
when site_address ! = '' then site_address
end as site_address
from parcel
what I'd like to do is have a variable and assign it to the value of the first column street_number, then when I move on to the next column, street_ext, if it isn't null I'd like to check to see if the variable is null and if not, append a space and the value...and so on down the road.
I'm rusty as hell and could use a push in the right direction.
Thanks everyone.
Use the "+" to concatenate strings in TSQL:
SELECT CASE
WHEN LEN(p.street_number) > 0 THEN p.street_number + ' '
ELSE ''
END +
CASE
WHEN p.street_ext = 50 THEN '1/2'
WHEN LEN(p.street_ext) > 0 THEN ''
ELSE p.street_ext
END + ' ' +
CASE
WHEN LEN(p.street_direct) > 0 THEN p.street_direct + ' '
ELSE ''
END +
CASE
WHEN LEN(p.site_street) > 0 THEN p.site_street + ' '
ELSE ''
END +
CASE
WHEN LEN(p.site_address) > 0 THEN p.site_address + ' '
ELSE ''
END AS full_address
FROM PARCEL p
The LEN function returns zero if the string value is NULL, or a zero length string.
Nested isnulls could do what you need. Something like:
SELECT
ISNULL(streetnumber + ' ', '')
+ ISNULL(streetext + ' ', '')
etc
relying on the fact that NULL + ' ' = NULL.
Something along the lines of:
select coalesce(street_number+' ','')+
coalesce(case when street_ext=50 then '1/2' else null end+' ','')+
coalesce(street_direct+' ','')+
coalesce(site_street+' ','')+
coalesce(site_address,'')
from parcel
I have assumed your data types are all varchar or similar for simplicity. If you are OK with removing any double spaces, how about:
rtrim(ltrim(replace(isnull(street_number) + ' '
+ isnull(street_ext) + ' '
+ isnull(street_direct) + ' '
+ isnull(site_street) + ' '
+ isnull(site_address), ' ', ' ')))
First I would declare the seperator as a variable, because customers are notorious for changing these.
I would do this as follows:
DECLARE #AddressSeperator NVARCHAR(5) = ' '
...and then for the column declation, I'd use the following:
, CONCAT
(
(CASE WHEN LEN(p.street_number) > 0 THEN p.street_number + #AddressSeperator ELSE '' END)
, (CASE WHEN p.street_ext = 50 THEN '1/2' + #AddressSeperator WHEN LEN(p.street_ext) > 0 THEN p.street_ext + #AddressSeperator ELSE '' END)
, (CASE WHEN LEN(p.street_direct) > 0 THEN p.street_direct + #AddressSeperator ELSE '' END)
, (CASE WHEN LEN(p.site_street) > 0 THEN p.site_street + #AddressSeperator ELSE '' END)
, ISNULL(p.site_address, '')
) AS [full_address]
I have the following SQL to format a US address into each line for a mailing address but it is rather ugly. Is there a better way to solve this problem or does it have to be this ugly? Also, the problem with this code is that it always ends up with an extra new line at the end.

If your Sql Server Settings are such that NULL + varchar returns NULL (SET CONCAT_NULL_YIELDS_NULL (Transact-SQL)), this can help.
DECLARE #Address TABLE(
ID INT,
AttentionLine VARCHAR(50),
Recipient VARCHAR(50),
AddlAddrLine VARCHAR(50),
DeliveryAddr VARCHAR(50),
LastLine VARCHAR(50),
Country VARCHAR(50)
)
declare #NL varchar(2);
set #NL = char(13) + char(10);
INSERT INTO #Address SELECT 1, NULL, '1', NULL, '2', NULL, '3'
select
case when rtrim(coalesce(AttentionLine,'') ) != '' then rtrim(AttentionLine ) + #NL else '' end
+ case when rtrim(coalesce(Recipient,'') ) != '' then rtrim(Recipient ) + #NL else '' end
+ case when rtrim(coalesce(AddlAddrLine,'') ) != '' then rtrim(AddlAddrLine ) + #NL else '' end
+ case when rtrim(coalesce(DeliveryAddr,'') ) != '' then rtrim(DeliveryAddr ) + #NL else '' end
+ case when rtrim(coalesce(LastLine,'') ) != '' then rtrim(LastLine ) + #NL else '' end
+ case when rtrim(coalesce(Country,'') ) != '' then rtrim(Country ) + #NL else '' end
as FormattedMailingAddress ,
RTRIM(coalesce(AttentionLine + #NL,'')) +
RTRIM(coalesce(Recipient + #NL,'')) +
RTRIM(coalesce(AddlAddrLine + #NL,'')) +
RTRIM(coalesce(DeliveryAddr + #NL,'')) +
RTRIM(coalesce(LastLine + #NL,'')) +
RTRIM(coalesce(Country + #NL,''))
from #Address
where Id = 1
I realize this is an old question, but there is a new solution to this problem: the CONCAT_WS() function, which is new for SQL Server 2017 (it's also available for Azure SQL Database).
SELECT CONCAT_WS (
CHAR(13) + CHAR(10), --Separator
NULLIF(AttentionLine, ''),
NULLIF(Recipient, ''),
NULLIF(AddlAddrLine, ''),
NULLIF(DeliveryAddr, ''),
NULLIF(LastLine, ''),
NULLIF(Country, '')
)
AS FormattedMailingAddress
FROM Address
WHERE Id = 1
NULL values are ignored by the function, which is why NULLIF is used with each argument/parameter in this example. (When the argument/parameter evaluates to NULL, the separator won't be added either). Here's a short blog post with some more details: New For SQL Server 2017: T-SQL Function CONCAT_WS
