constructing strings from table

Hi friends,
please help me in selecting values from the table
the record is as follows:
Id HomePhone WorkPhone Mobile Email
20 2323223 323232232 test@.test.com
i have to select values as follows.
Id DeviceType DeviceInfo
20 HomePhone, Mobile, Email 2323223, 323232232, test@.test.com
the one solution is:
select
'HomePhone, Mobile, Email' AS DeviceType
HomePhone + ',' + WorkPhone + ',' + MobilePhone + ',' + Email AS
DeviceInfo
from table where Id = 20
but here the work phone number is not available so that information
has to be truncated...
Thanks in Advance

Use the same thinking as was suggested in my earlier reply:
SELECT
No
,'HomePhone, ' + CASE WHEN WorkPhone IS NOT NULL THEN 'WorkPhone' + ', ' ELSE '' END + 'Mobile' AS
DeviceType
,HomePhone + ', ' + COALESCE(WorkPhone + ', ', '') + Mobile
FROM
(
SELECT 20 AS No, '23232' AS HomePhone, NULL AS WorkPhone, '98327' AS Mobile
) AS x

constructing strings from table

Hi friends,
i have to select values from the table consider with the following
record:
No HomePhone WorkPhone Mobile
20 23232 98327
the selection have to be done as:
No DeviceType DeviceInfo
20 HomePhone, Mobile 23232, 98327
since there is no value for workphone it have to be removed in both
devicetype and deviceinfo column.
Thanks

Something like (assuming NULL when you say "no value"):
SELECT
No
,'HomePhone, ' + CASE WHEN WorkPhone IS NULL THEN 'WorkPhone' + ', ' ELSE '' END + 'Mobile' AS
DeviceType
,HomePhone + ', ' + COALESCE(WorkPhone + ', ', '') + Mobile
FROM ...

What about something like:
SELECT No,
CASE WHEN HomePhone IS NULL THEN '' ELSE 'HomePhone' END +
CASE WHEN WorkPhone IS NULL THEN '' ELSE 'WorkPhone' END +
CASE WHEN Mobile IS NULL THEN '' ELSE 'Mobile' END
AS DeviceType,
CASE WHEN HomePhone IS NULL THEN '' ELSE HomePhone END +
CASE WHEN WorkPhone IS NULL THEN '' ELSE WorkPhone END +
CASE WHEN Mobile IS NULL THEN '' ELSE Mobile END
AS DeviceInfo
FROM TableName
(You will need to add a bit of logic to work out where to put the commas)

Provided that WorkPhone is blank, the query above make sense to me.
The output would be "2323223,,323232232,test@.test.com". But if the
double comma wasn't there, how would you know which number that is
missing?

If WorkPhone is NULL, the entire expression will be NULL. In this
case you must use coalesce(WorkPhone, '') and similar for the other
columns.

The solution i have given is a static one.
The above solution holds good when all the column have value in it.
but when one column, say "HomePhone" is not available the resulting
table should build as

Id DeviceType DeviceInfo
20 Mobile, Email 323232232, t...@.test.com

please help me in this regards.|||Oonz (arundhaj@.gmail.com) writes:

Use the CASE exprssion:

SELECT DeviceType = CASE WHEN HomePhone IS NOT NULL
THEN HomePhone + ','
ELSE ''
END +
CASE WHEN WorkPhone IS NOT NULL
THEN WorkdPhone + ','
ELSE ''
END ...

It gets a little devilish if the email is missing as you may end with a
trailing comma, but maybe you can live wity that.

constraints and altering tables

I'm in the process of trying to convert a database such that all the strings
(VARCHAR) are converted to wide strings (NVARCHAR). I have a script that
accomplishes this by removing all the primary key constraints, converts the
necessary columns, and then replaces the constraints. The script walks the
sysnames table and stores all the constraints in a table variable, and
constructs a script to recreate all the constraings based on the 'xtype'
column from sysindexes (this is based on the system stored procedure
sp_pkeys). The script creates a constraint if the xtype is of type 'PK', or
creates an index based on the INDEXPROPERTY of the index, whether it be
unique, and either clustered or non-clustered.
This works for the most part, but I have found that there are constraints
being created on some columns that did not exist before the conversion. For
example, I have a table which has a primary key on it's identity columns
defined to automatically insert a new value at each insert incremented by 1.
After the conversion, there is an additional constraint placed on this table
which prevents a value of NULL from being added, which should be a problem
due to the IDENTITY column, yet attempting to do an insert on this table
generates an error saying that a NULL value cannot be inserted. I'm not
manually inserting anything, this should just bump the id value by one and
do the insert, but this new constraint prevents this, leaving me with a
table I can no longer insert into.
In another case, I have several varchar columns that have default
constraints (simple text strings), which are also dropped before conversion.
Upon replacing the constraints read from sysnames, I get similar errors
regarding not being able to insert nulls into these columns, which I didn't
get before, as these columns had default values.
My questions are, is it possible to exactly recreate constraints
programmatically? Is there a preffered method for converting databases from
narrow to wide character?
Thanks for any advice,

Is the IDENTITY property still set for the column? If so, then what does
your INSERT statement look like? If not, then your script is, well,
imperfect.|||Yes, It is still set. the insert statement does inserts using enumerated
column names.
INSERT INTO RptTable (

ExportReport, ExportDaily, ExportWly, ExportMonthly, ExportFormat,

The identity is on a column called ReportId, which is defined as (at table

Perhaps there is an INSTEAD OF trigger on the table (which requires that
you specify values for all non-null columns that have no DEFAULT constraint,
even if those values will not ultimately be inserted anywhere), or you have
IDENTITY_INSERT set to ON for this table.
If these guesses are wrong, please cut and paste the error message you get.
