Hello,
I can raise this message from an Update Trigger in Query Analyzer when I
update the recordID field of my table:
RAISERROR ('this is a test message from SubDetail Update 7', 16, 10)
Is it possible to raise this message from an external app? How is this
achieved? Actually, I am sure this is possible because I remember doing it.
I just can't remember what I did because I did not document it.
Thanks,
RichWhat is this "external app"? An application that you write yourself? A TSQL
error (which is what you
raise using RAISERROR) is returned to the client application. The client app
lications is connected
to the database using an API, like ADO.NET. And, sure, you can have your dat
abase application
connect to SQL Server and issue a RAISERROR command, and have that error mes
sage be returned to the
same app, but that sounds a bit ... meaningless. If you give us more informa
tion, we can probably
give some suggestion.

few months ago, and I added a raiseerror message at the end to see my result
s
in QA - not error results - just checking what parameter was being used. I
accidentally left the raiseerror message in the trigger, and then I got a
call from an End User stating that this message was coming up all of a sudde
n
when she made updates to the table.
I found the table and reactivated the raiseerror message and I get it when I
updaet a field. The only thing I noticed is that the field I update in this
table (the master table) is not a key field. In the Detail table when I
update the RecordID field this action does not raise the message like in the
Master table. I guess my question is if this is something fundamental that
I
am missing or is it something that I need to dig around to see what is going
on?

writing to the table through a form. But if I update the table
programmatically from the ADP, then the message does not come up.
While I am at it, I want to alter/replace my raiseerror message. I used the
sp_addmessage sp. Since my message already exists as 50001, I don't want to
add another message. I want to alter this one. But I get an error message
in QA saying that I need to use REPLACE to alter the message for ID 50001.
I
don't know the syntax for this. I have tried variations such as:
USE master
EXEC sp_addmessage 50001, 16,
select replace('This is a test custome message', 'custome', 'custom')
and placing REplace in other locations with no success. Any suggestions how
to do this correctly would be greatly appreciated.

If you see the error when executing a statement which will result in the tri
gger being called using
TSQL but not when using ADP, then probably ADP is masking that error and you
should check with an
Access group to see how you can rectify this behavior in Access. Use Profile
r to catch the TSQL
command being submitted from Access just to make sure of what is happening o
n the server level.
Here is how you replace a message text:
EXEC sp_addmessage 50001, 16,
N'Old message text'
GO
EXEC sp_addmessage 50001, 16,
N'NEW message text', @.replace = 'replace'
GO
RAISERROR(50001, -1, 1)
