Help ASP; get last inserted value from one table, insert multiple rows in another table.

P: n/a
PT
I got a problem. And thats.....

First of all, I got these three tables.

------------------- ------------------ ----------------------
tblPerson tblPersonSoftware tblSoftware
------------------- ------------------ ----------------------
PID PName PID* SID* SID SWName
--- ----- --- --- --- ------
1 Thomas 1 1 1 MS Office
2 Mark 1 2 2 Visual Studio
3 Philip 2 3 3 Dreamweaver
.. .... 3 1 4 SQL Server
.. .... . . . ..........
------------------- ------------------ ----------------------
* - foreign key

Now I got a form in asp, with textbox (to insert persons name into
table 'tblPerson') and checkboxes (created dynamically from table
'tblSoftware'). One can choose check any softwares needed. And these
values should be inserted into table 'tblPersonSoftware'.

First I have to insert persons name into 'tblPerson', get the ID from
it (from the last inserted value), get the values of checked
checkboxes, and insert multiple records in 'tblPersonSoftware' with
PID from the last inserted value in 'tblPerson' and SID with the
values of checkboxes.

I created the form with Dreamweaver. I'll show the code that I have
now.

My goodness - what a mess of code.

Judging by the tablename, you are using SQL Server. If so, and the "ID"
field is an IDENTITY field you can use:

"SELECT Scope_Identity"

to return the identity value of the last created record.

strSQL = "SELECT Scope_Identity"
Set objRS = objConn.Execute strSQL
If not objRS.EOF then
intLastID = objRS.Fields(0).Value
End If
objRS.Close
Set objRS = Nothing

NOTE: You must use the same connection object that you used to do the
original INSERT. Looking at your code, it seems to be some of that
Macromedia auto-generated rubbish. That usually uses implicit connections -
you;ll need to explicitly open a connection and re-use it -or- use a sproc
to do this.
