I don't see why you would have to update each column in an individual
query. Why not SET all the columns in one UPDATE? The code below
would simplify that. @tablename is used rather than a hardcoded value
to facilitate turning it into a stored procedure.
declare @tblname nvarchar(60)
set @tblname = 'PROFILE'
SELECT CASE WHEN C.colid = 1
THEN 'UPDATE ' + O.name + CHAR(13) + CHAR(10) +
' SET '
ELSE ' '
END +
C.name + '= replace(cast(' + C.name +
' as nvarchar(255)),char(13)+char(10),'':'')' +
CASE
WHEN C.colid < (select max(colid) from syscolumns CC
where O.id = CC.id)
THEN ','
ELSE ';'
END
FROM sysobjects O
JOIN syscolumns C
ON O.id = C.id
WHERE O.name = @tblname
ORDER BY C.id, C.colid
Output from one test exeuction:
UPDATE HoldEventsTable
SET TelephoneCallID= replace(cast(TelephoneCallID as
nvarchar(255)),char(13)+char(10),':'),
Time= replace(cast(Time as
nvarchar(255)),char(13)+char(10),':'),
Event= replace(cast(Event as
nvarchar(255)),char(13)+char(10),':');
