I am trying to run an SQL query for each item in an Array using ASP.
I have coded it as such. IDsArray() is an array of integers. -
ArrayLength=15
-
-
sqlGetiIDs = "SELECT * FROM Table1 WHERE (dID = " & IDsArray(j) & ")"
-
j=0
-
Dim GetiIDsRSArray(ArrayLength)
-
-
do
-
set GetiIDsRSArray(j) = conn.execute(sqlGetiIDs)
-
j=j+1
-
loop until j=ArrayLength
-
First, I get an error while declaring the array: "Expected integer constant." Why doesn't it see the variable as an integer, and how can I fix it?
Second, this seems extremely awkward to create this array of recordsets. Can anyone suggest a better methodology? I would rather have it saved into one large recordset.
Many Thanks.

I got it - I was trying to do it the hard way.
The right way to do this is from the back end, the actual database.
I created a UNION and made the array part of an actual table. Then I could run querys on it as normal and I would have access to all the data points at the same time.
I don't need it anymore, but just curious - I still don't know why the array declaration wouldn't take the variable, do anyone know about that?

first, I noticed this problem before as well, I think vbscript might need a constant, rather than a variable, to define arrays. don't ask me why, it works everywhere else.
second, try: - 'just to simplify a little bit, let's take out the parenthases which
-
'are not necessary in such a straight-forward query statement
-
'and let's put the conditions in a series of OR clauses
-
sqlGetiIDs = "SELECT * FROM Table1 WHERE "
-
for j = 0 to 15
-
sqlGetiIDs = sqlGetiIDs & "dID = " & IDsArray(j) & " OR "
-
next
-
-
'sqlGetiIDs currently ends with " OR " which needs to be removed thus:
-
sqlGetiIDs = left(sqlGetiIDs, len(sqlGetiIDs)-4)
-
-
'it's a good idea to check the final string just to make sure it looks right:
-
response.write "<!-- sqlGetiIDs: " & sqlGetiIDs & " -->" & vbNewLine
-
-
'then send this to your recordset object:
-
objRS.open sqlGetiIDs, conn
-
'I just like to say "open" rather than "execute", your call, really.
Does this make sense?

I'm a little nervous about slamming my database with a dozen Update queries
in a loop that all modify RecordSources of open forms. Will the use of
DoEvents and/or a Sleep function ameliorate any risk involved in doing this?
Should I include a Requery in the loop after executing each query?
For example:
For each varQry in Array("qryDeleteOldTransactions", _
"qryDeleteClient Acct", etc., etc.)

Lets say I have 10 products in 10 different stores and every week I get a
report from each store telling me how many items they have left for each of
the 10 products.
So each week I enter in 100 records with a store number, item number, on
hand qty, and date of report into my sales data table.
My tables primary is a combo of store# & Item number & Date
After 10 week of this I have 1000 record total with ten unique dates.
