SQL tidy up address data

Hi All

I have an address table from which I need to print address labels. ie

Address1, Address2, Address3, PostalCode

Some of these fields are empty, so I want the next available field to be in the position of the missing data so when printed the address is on consecutive lines with no spaces.

IE
Address1
address3
Postalcode

Note address2 is missing, but there is no place holder for where it should be.

Any idea on how I can achieve this?

It depends what sort of application you are printing from as to what link break characters you need but something like the following should work where you can set the line break to be either a regular "\n\r" or html (I only mention HTML because thats how I normally do it).

declare @LineBreak varchar(4)

set @LineBreak = '<br>'

select
  Address1
  + case when isnull(Address2,'') <> '' then @LineBreak + Address2 else '' end
  + case when isnull(Address3,'') <> '' then @LineBreak + Address3 else '' end
  + case when isnull(PostalCode,'') <> '' then @LineBreak + PostalCode else '' end

I'm printing to a report engine where each address field has its own container. IE there are 4 text fields address1 - 4 & postcode.

I guess I could go with 1 field and use your solution.

Maybe you can use different SELECTs with UNION:

SELECT IE, address1, address2, address3, PostalCode
FROM your_table
WHERE address1 IS NOT NULL AND address1<>''
     AND address2 IS NOT NULL AND address2<>''
    AND address3 IS NOT NULL AND address3<>''
UNION
SELECT IE, address1, address2, PostalCode, ''
FROM your_table
WHERE address1 IS NOT NULL AND address1<>''
     AND address2 IS NOT NULL AND address2<>''
    AND (address3 IS NULL OR address3='')
UNION
SELECT IE, address1, PostalCode,'',''
FROM your_table
WHERE address1 IS NOT NULL AND address1<>''
     AND (address2 IS NULL OR address2='')
    AND (address3 IS NULL OR address3='');

hope it helps.

Thanks Guys. Have gone with this as it gives me more options. Able to drop a HTML field on the report and displays fine.
