Alternating INSERTs fail

In SQL Server 7, I have a stored procedure that does a simple INSERT. I cal
l
it from ASP.NET.
It only succeeds every other time (i.e. alternating). No error is returned
when it doesn't work. A return value of 1 is always returned for both cases
(indicating 1 row affected) but the new data row simply isn't there exactly
every other time, alternating.
I even ran a trace, and I can see both inserts happen , and nothing else
comes along to delete any of the rows. But the problem persists.
The only difference that I see in the trace is the number of reads, and a
longer duration in the one that succeeds (the second one):
Event Class Object ID Database ID Text Application Name NT User Name SQL
User Name CPU Reads Writes Duration Connectio
n ID SPID Start Time
+RPC:Completed 9 InsertAccountLogin 377864, N'Dec12-Test7', N'Dec12-Test'
.Net SqlClient Data Provider sa 0 4 0 0 22591 20 14:57:14.380
Event Class Object ID Database ID Text Application Name NT User Name SQL

.Net SqlClient Data Provider sa 0 3 0 17 22591 20 14:57:30.223
Can anyone suggest some more troubleshooting steps I can take here?
I've tried it with the stored procedure as:
================================
CREATE PROCEDURE InsertAccountLogin @.InternetID as int, @.UserName as
char(40), @.Password as char(15) AS
Begin Transaction
Insert into AccountLogin (InternetID, UserName, Password) Values
(@.InternetID, @.UserName, @.Password)
COMMIT Transaction
================================
and also
================================
CREATE PROCEDURE InsertAccountLogin @.InternetID as int, @.UserName as
char(40), @.Password as char(15) AS
Insert into AccountLogin (InternetID, UserName, Password) Values
(@.InternetID, @.UserName, @.Password)
================================
Thanks,
Greg HolmesYou might try adding the sp:statement completed event to the trace. Do you
have any triggers on the table?
Hope this helps.

Thanks Dan. I added statement completed to the trace, but all that did was
add a
"sp:statement completed" line before each RPC line for the INSERTs. Those
"sp:statement completed" lines look identical.
This is so weird. The first field in the insert should be incrementing by
1s (by the ASP.NET application), but you can look at the rows and watch it g
o
up by 2s. I also added an auto incrementing field to the table and you can
watch the phenomenon there too ("1", "3", "5", etc.). It's actually
incrementing the auto-incrementing field, but not leaving a row in the
database, every other time.

1. Switch from using Stored Procedure to local text SQL query.
2. Add an auto-incrementing identity field to the database.
Has to do both. Neither worked by itself.

That might have worked.

I was curious about the data in the InternetID and the new IDENTITY column.
Does the InternetID still increment by 2? What about the IDENTITY col?
Hope this helps.

and now that I have the identity column in the table, the INSERTs work as
expected. The identity column increments by 1, as does InternetID (if
sequential customers both create an account, which is what this table is for
).
So by changing those two things, I must have somehow worked around an issue
that I don't understand, or perhaps an obscure bug.
