The ASP application inserts transaction records in transaction table
with the system time as the primary key. However, it is possible to
have primary key violation because the records in transaction table
come from different sources. The application can show error message and
the user can file a transaction again manually, but I want the
application can have multiple re-tries to perform insert statement
until there is no primary key violation.
Here's the code, but I get stuck what code should i put to re-try the
insert statement, a for loop?and perhaps re-try 3 times before showing
the primary key violation error message to the user?
<%
set conn = CreateObject("A DODB.Connection ")
conn.open "<connectio n string>"
sql = "insert into p_tran values (convert(varcha r, GETDATE(), 109),
amount)"
conn.execute(sq l)
if err.number <0 then
Response.Write err.description
end if
conn.close
set conn = nothing
%>

No you should change you design and stop using the system time as a primary
key.

set conn = CreateObject("A DODB.Connection ")
conn.open "<connectio n string>"
sql = "insert into p_tran values (convert(varcha r, GETDATE(), 109),
amount)"
conn.execute(sq l)

....although this is just a sticking plaster over the gaping wound.
Raising errors is expensive, and using a PK that's likely to raise this
sort of error is poor design. Change your PK to something that's much
more likely to be unique.

This is a repost, I hope with a better explanation:
1. Create 3 tables, all with 2 fields:
Table 1: Field IDnr (Autonumber,key) and Field Test1 (Alpha50)
Table 2: Field IDnr (Number,key) and Field Test2 (Alpha50)
Table 3: Field IDnr (Number,key) and Field Test3 (Alpha50)
2. In the relation window link on IDnr: table 2 to table 1 (1x1) and table 3
to table 1 (1x1).

I know there are no pointers in C#, but if you do:
a = b;
and a and b are both arrays, they now both point to the same memory
(changing one changes the other). So, it makes them seem like
pointers.
Can someone please explain why? thanks.

Hi, I've got a database with front-ends at multiple locations that pull from a primary back-end over a satellite network. Each time a front-end closes it triggers a back-up utility that creates a back-up of the primary back-end on that front-end's local network; so that in the event the link is lost to the primary back-end, that location's will automatically connect to the back-up back-end. Confused yet, good me too.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
