Process works fine... how to track which column is causing error..

Question

hi, i have a big sp which does lets say tasks A, B, C, D...
After every task i.e A, B, C, D I have an update or insert
statement. The update & insert both work fine, except that I
have coldfusion catch code for sp execution and it returns String
or binary data would be truncated error. Normally this means
inserting something into a column whose lenght is less than whats
being inserted. I understand this , but how can i determine which
column is causing problem since after tasks A,B,C,D the insert or
update i have is working fine. It would be have easy if i couldnt
have seen inserted or updated records, but in this case the
functionality is working fine except that coldfusin gives an error
which i want to avoid.
Thanks in advance.

Yes, if the database column is smalldatetime then then
@start_date should be smalldatetime.
However, the SP's input variable (call it say,
"RawStartDate") can still be varchar for the reasons you stated.
Just be sure to return the appropriate error and/or insert a valid
smalldatetime always.
Sorry for confusion... GetDate was just an example , it could
another variable @end_date which is varchar(20).
so we could have SET @start_date =
CAST(convert(varchar(20),@enddate,101) as datetime)
Now coming back to main problem.. I am not calling the SP
from coldfusion. I am directly running it thru Query Analyser and
here is what iam getting for a date value passed as '2006-05-24
00:00:00.000'
Server: Msg 295, Level 16, State 3, Procedure WS_AUTO_INTAKE,
Line 263
Syntax error converting character string to smalldatetime
data type.
here is the query starting at line 263
INSERT INTO intake_seq (intake_id, intake_seq, absence_type,
start_date, start_time, end_date, end_time)
VALUES (@intake_id, 1, @absence_type, cast(@start_date as
smalldatetime), DATEADD ( hh , 8, cast(@start_date as
smalldatetime)), cast(@end_date as smalldatetime), DATEADD ( hh ,
16, cast(@start_date as smalldatetime)) )
You would say, ok try just datetime instead of
smalldatetime...tried that also .. it gives this error
Server: Msg 241, Level 16, State 1, Procedure WS_AUTO_INTAKE,
Line 263
Syntax error converting datetime from character string.
Its all got to do with this value '2006-05-24 00:00:00.000'
which is passed as one of the parameters to sp call... I tried with
this and gives error... when i removed the last 3 zeroes with . ,
it works fine ...example '2006-05-24 00:00:00'
What is wrong here? Iam I missing something????
by the way , this SP is working fine for 99% of time... its
just that on very few occassions iam seeing the error... thats the
reason i persisted with SP INPUT VARIABLES declared as VARCHAR
rather than int or datetime, ....
any ideas????
I know I can have convert(varchar(20), @start_date,101) to
get the format dd/mm/yy but then I have to cast it to datetime
which will again make it in format dd/mm/yy hh:mi:ss... any other
way to just keep it dd:mm:yy ???
