Question

I have been working with classic ASP and database access through it. The database im using is MySQL. The ASP pages are running on IIS 7.
I developed two ASP pages. First, here is the schema im working with-

Book = (b_id, title, pages, price, p_id)

Publisher = (p_id, name, country)

p_id in Book is a foreign key from Publisher.

Now, in one script, when adding record in Publisher, i first check whether similar record exists and if it does then report that to user. That script works fine.

But in other script to insert record in Book, i first check whether the specified publisher exists or not. But for some reason, that doesnt work at all. That is, when i query the Publisher table to get all records for comparision, the RecordCount property of the RecordSet object returns -1.

I have checked both scripts extensively for errors and there are none.

Why is the same code for the same purpose not working in one but working in the other ?

The working code –

flag = false
temprs.Open "select country from publisher where name='" & pubname & "'", conn
if temprs.RecordCount <> 0 then
    do while not temprs.EOF
        if temprs.fields("country") = pubcountry then
            flag = true
            exit do
        end if
        temprs.MoveNext
    loop
end if

It goes into the loop in the above code.

And the code thats not working –

q = "select p_id from publisher where name='" & bookpub & "'"
prs.Open q, conn
pins = false
if prs.RecordCount > 0 then
    pid = prs.fields("p_id")
    pins = true
end if

Here, prs.RecordCount returns -1. All variables have been Dim-med in the earlier portion of the code.

Answer 1

Can I offer a different solution that gives you the same result but without using recordcount:

q = "select p_id from publisher where name='" & bookpub & "'"
prs.Open q, conn
pins = false
if not prs.eof then
    pid = prs("p_id")
    pins = true
end if
