Class To Ease Use Of GetRows()
I was bored this weekend and after reading a couple articles and posts about GetRows() being WAY better than the usual way, I thought I would try and make a class to make it similar to using a recordset.
It's far from finished but I thought I would throw it up here and see what everyone thought. Am I wasting my time? I have no real way of benchmarking the possible improvements but I haven't been able to notice a difference yet. Anyway, you can download it here. The zip includes the class file and an example asp file.

I'm using getRows in two different SELECT stataments and want to know if it's possible to place the data in the two getRows into one array? Lets's say I have something like this:
Set rs = Server.CreateObject("ADODB.Recordset")
strSQL = "Select test FROM Table WHERE id = "&id&""
rs.Open strSQL, Conn
contentFirst = rs.GetRows
Set rs2 = Server.CreateObject("ADODB.Recordset")
strSQL2 = "Select id FROM Table WHERE id = "&id2&""
rs2.Open strSQL2, Conn
contentSecond = rs2.GetRows
Now what I want is a variable that holds the content of contentFirst and contentSecond like this: content = contentFirst + contentSecond
Can this be done in some way with arrayas? How?

I was reading a sample on ASP101 (i love them), and it was, I think, saying u could specify the record u want to start at...is that true? If so, I think EVERYONE should use it...it would be very cool.
Because, if u need the 6th record, u can just get it, but, using a recordset, it would be, i believe, impossible...right?, or is that wat bookmarks are for?

I'm using getrows to return the values from two columns in a MSSQL sql
database. Looping through them like so:
dim irowloop, icolloop, i
for irowloop = 0 to ubound(instances, 2)
for icolloop = 0 to ubound(instances, 1)
response.write("<option value=""VAL"">") 'get 2nd col val
response.write(i(icolloop, irowloop))
response.write("</option>")
next
next
How can I get the value of the second column into the VALUE=""attribute in the drop down?

I am getting information out of a table to place into to an Array.
rs=DataConn.Execute(strSQL)
At this point I place it into the array
objArray=rs.GetRows()
But how do I handle things if the rs came back blank? What happens is that the loop encounters an error?

I built a recursive forum (tree) with ASP (VBS) and getRows and the DB Microsoft Access.
When I tried to add a pages division (with ADO) it destroyed everything
The relevant code:
The ADO pages devision:
rs.PageSize = MessagesNum
rs.CacheSize = MessagesNum
If Not rs.EOF Then
PagesCount = rs.PageCount
rs.AbsolutePage = Page
arr = rs.getRows
End If
Code:

I have the following:
dim app_ids, irowloop, icolloop
app_ids = get_app_logins(session("stremail"))
for irowloop = 0 to ubound(app_ids, 2)
for icolloop = 0 to ubound(app_ids, 1)
response.write(app_ids(icolloop, irowloop) & ",")
next 'icolloop
response.write("|")
next 'irowloop
That returns:
0,0,bobsmith,pAssWord,|0,71,tom,tom,|0,71,tomf,pAs sWord,|1,5,tom,a1,|
Is it possible to remove the final ',' before the '|' ??

I recently learned about the wonders of the getrows statement on a recordset (IE alldata=rstemp.getrows). It dumps a recordset into an array, that I get. Sounds great! My question is: Is there a way to support a SQL shape statement using the getrows statement? I'm guessing that if I try to throw that into a variable it may not like it.

I know that getstring or getrows increase performance but my question when to use this method. This is because what I know is this method will output all fields in a table and not just certain few.

' Loop through the array holding the result set and display the data
For iCounter= varC1Begin to varC1End
Response.Write("<a href=prices.asp?manuf=" & arrResultSet(0,iCounter) & ">"
& arrResultSet(0,iCounter) & "</a><br>")
Next
%>
In the above Response.Write statement arrResultSet(0,iCounter) displays the
manufacturer just like it should.
However, within the hyperlink, if a manufacturer has 2,3, or more words, it
will only show the first word. Anything after the first space is ignored.
Why?

When querying a database, I know I can fix the no. of returned rows/results to 20 (for example) using the GetString method:
myVar = objRs.GetString(, 20, , ,)
What syntax do I need to use to do the same with the GetRows method:
myVar = objRs.GetRows ?

I currently thinking of converting from my little knowledge of
VBscript to jScript ASP.
With this in mind I'm looking at my current code to see how it will
convert over to Jscript.
One thing I have spotted that I can't think of a way round is the ADO
recordset.GetRows command.
I have a VBscript class that handles my DB connections so in short I
can do things like
MyArray = clsDB.GetRecordsInArray("Stored Proc Name/SQL", other
params)
and this would return the rows into a 2 dimension array.
Problem is I've read that Jscript only has one dimension. So how is
the "getRows" solved for Jscript.
Also is there any good "Jscript" code learning sites?

I am reading an recordset into an array using getrows, but my recordset has 38 records but my array has 46!!
If I loop through the array, it errors on number 38 (as expected). I am using UBound to find the array length.
can anyone think what is going wrong, without the need to post my code (step 2!)?

I'm using the following JOIN query;
Code:
strQuery = "SELECT whoisserver.host, [domain].domainid, [domain].[domain]" & _
" FROM [domain] INNER JOIN [whoisserver] ON [domain].whoisserverid = whoisserver.whoisserverid"
Which works perfectly. when I use getRows to store the results in an array, the whoisserver.host field isn't in the array. Only the domain.* fields are in the array. Anyone know why this is, and how to solve it? I really need that whoisserver field.

I'm using getrows to speed up data access time, i wonder though if there is a better way. Each recordset returns up to or more than 500 records, this is still quite an overhead for the server when there are lots of people on the site.
Rather than reading all 500 records into the array and then paging the results is it possible to create the recordset with just 25 entries?
ie if you are on page 1 then only the first 25 records are retrieved from the database, page 2 - records 25 - 49 are retrieved etc
or will this slow things down?

im developing a Product configurator (just like alienware use) where in my database i have
(systems table) a list of PC systems
systemID
(categories table) a list of PC product categories (ie. CPU, RAM...)
categoryID
(products table) a list of all products
productID, catID
(link table)
sysID and prodID
Now before i put the code ive done so far, let me explain that the first page lists all systems wich then gives the systemID for the link table. Once this page loads it needs to go through each category then list the products available to that category where sysID = systemID. Now a query i put together to list all products for that sysID is:
select * from PRODUCTS inner join link on link.prodID = PRODUCTS.productID where link.sysID=systemID
Now this query works great and lists all of the products for that systemID, but what im unable to do is (using GetRows()) have the category name listed as a title then have each product under the respected category. Code:

would this code give an EOF or BOF error if there are no rows in the

I can't seem to get the getrows function of an ADO recordset to work or get a dictionary object to work. I've made them work on other servers before using the same code.
Server is running Windows Powered and IIS 5.0I can provide code, but you must believe this code has worked on other servers.

I'm using an SQL statement like the following:
Code:
INSERT INTO table (field) VALUES (value) SELECT @@IDENTITY AS NewIdent;
If I run it through a command prompt (osql.exe) it works fine - it inserts the data and returns the new identity. However, when I try to pass this through my nifty GetRows() function the stupid thing chokes (it acts like a normal INSERT statement has been passed - "ADODB.Recordset (0x800A0E78) Operation is not allowed when the object is closed." on the line where I try to execute GetRows).
I've looked through my ADO documentation and don't see any reason why this should be happening (since it does return data). Due to the small amount of data, I'm going to just use a plain old RecordSet object, but for my own piece of mind does anyone know why it won't treat the returned @@IDENTITY variable like normal data?

if there is anyone knows if its possible to put a database columns' value such as ( Title, Name, IP, Phone, Address, etc... ) into array then retrieve them to be displayed on page via Access in ASP using getrows but utilize something similar to rs("Title"), rs("Name"), rs("IP"), etc., or create temperay new variables such as rs(vTitle), rs(vName), rs(vIP), instead of using the rs( row, column ).
The reason I am asking is that when a table has many fields, its gets hard to track down the right array number instead of simply using its column or field name.I have written paging scripts based on ADO method of getting rs("FIELDNAME") to display datas, and I am trying to convert it to utilize getrows() method, but having trouble with the array column sequence.

I'm using .getRows() with a local var array instead of doing a recursive
loop so that I'm being a good ASP newvbie and closing my object i/o's (the
recordset in this case) as quick as possible.
My problem is that I can't seem to use this to complete good effect because
the IsArray statement doesn't seem to work with a local var array that has
or has not been populated with the .getRows() property.
To explain, I used to do the following recursive loop (simplified to show a
concise example): Code:

SET objSecurty = new Security

Session("Security") = objSecurity

I am working with a bunch of old code so I can really restructure the includes, otherwise I guess I could change all the #include statements to #include-once. Anyway, If I have a file with a class like this:
Class myClass
end class
I get a "name redefined" error. I've been seeing these and indeed from goolge searches, it's because the file is somehow included more than once. This problem doesn't occur for functions and the old code bases just used functions whereas I would like to add some classes. In C you used to be able to detect that at the top of the file and not included the rest of the file if it is allready included. I just want to at least detect it so I don't redeclare the class.
