I have 4 fields in My table Name, Addr1, Addr2, Addr3.

e.g.
Name:          J Smith
Addr1          37 Main Street
Addr2          Auckland
Addr3          Null

I would like to combine these into one field that reads:-

J Smith, 37 Main Street, Auckland

Is there a way to do this with a case statement it function - I would like to select this table and list one field in the format above.

You can achieve it witout CASE Statement by concatenating the fields as follows:

Select NAME + ',' + ' ' + Addr1 + ' ' + Addr2 +',' +  ' ' + Addr3 From Tablename

Hope this helps

Cheers.

Select Name + COALESCE(', ' + Addr1,'') + COALESCE(', ' + Addr2,'')  + COALESCE(', ' + Addr3,'')
from TableName

OK - can just concatenate but I have a large number of records - some with no values in so to create this statement I need to do something to put the comma in the right place.

i.e. if first field null or '' then don't put a comma after first field - If any other field is null or '' then don't put a comma before it.

Select NAME + ',' + ' ' + Addr1 + ' ' + Addr2 +',' +  ' ' + Addr3,
CASE WHEN NAME IS NULL THEN (NAME + ' ' + Addr1 + ' ' + Addr2 +',' +  ' ' + Addr3),
CASE WHEN ADDR1 IS NULL THEN (NAME + ',' + ' ' + Addr1 + ' ' + Addr2 +',' +  ' ' + Addr3),...SO ON
ELSE ''
END AS O
 From Tablename

Select Replace(Name + ',' + Coalesce(Addr1,'') + ',' + coalesce(Addr2,'') + ',' +  Coalesce(Addr3,'') + ',' + Coalesce(Addr4,''),',,','')  'Address' From MyTable

Create a computed column -- one time -- on the table, like so:

ALTER TABLE tablename
    ADD NameAndAddress AS Name + COALESCE(', ' + Addr1, '') + COALESCE(', ' + Addr2, '') + COALESCE(', ' + Addr3, '')

Then use that new name like any other column, for example:

SELECT NameAndAddress
FROM ...
WHERE NameAndAddress LIKE '%...%'
ORDER BY NameAndAddress

The code assumes:
1) name is always present
2) a missing address value will be NULL not '' (empty).

If either of those are wrong, pls let me know.

Thanks for suggestions. I have had another think through and have come up with the statement below.

SELECT     Name + CASE WHEN Name IS NULL OR
                      Name = '' OR
                      Addr1 IS NULL OR
                      Addr1 = '' THEN '' ELSE ', ' END + Addr1 + CASE WHEN Addr2 IS NULL OR
                      Addr2 = '' THEN '' ELSE ', ' END + Addr2 + CASE WHEN Addr3 IS NULL OR
                      Addr3 = '' THEN '' ELSE ', ' END + Addr3 + CASE WHEN Addr4 IS NULL OR
                      Addr4 = '' THEN '' ELSE ', ' END + Addr4 + CASE WHEN Addr5 IS NULL OR
                      Addr5 = '' THEN '' ELSE ', ' END AS LongAddress
FROM         Cust_Table

This seems to work OK. In the examples given Coalesce and Replace where used. I would be interested to know the purpose of using these.
