I assume you are wanting to sort on the name column here. If so, add ORDER BY Name to the end of your select.

In looking at your data sorting wish, the only organization I see that makes any sense is to sort like "ORDER BY LEN([Name]) DESC, [Name] ASC".

Hi guys.I want to establish a connection to my MS Access database using my HTML or ASP code.The problem is that I have to load database values onto the dropdownlist when I run the page but I say its the connection because the page run with no values and no dropdown.I havent been able to run any values in other examples that Ive tries.Is there configurations that I need to change in ASP or HTML to run database connections in ASP and HTML.
Here is the code I got a problem with
<%@LANGUAGE="VBSCRIPT" %>
<%
Option Explicit
Dim objConn
Dim objRS
Dim objRS2
Dim strSQL
Set objConn = Server.CreateObject("ADODB.Connection")
Set objRS = Server.CreateObject("ADODB.Recordset")
Set objRS2 = Server.CreateObject("ADODB.Recordset")
objConn.ConnectionString = Server.MapPath("dropdowns.mdb")
objConn.Provider = "Microsoft.Jet.OLEDB.4.0"
objConn.Open
'-- Sub Procedure that builds the dropdown list.
'-- Parameters c, r and table are passed when the sub is built.
Sub showDropDownList(c, r, table)
'-- SQL Statement
strSQL = "SELECT * FROM " & tblDropDownTest & " ORDER BY Title ASC"
'-- Execute our SQL statement and store the recordset
Set r = c.Execute(strSQL)
'-- START MAIN CODE BLOCK
'-- If we have records to return
if not r.eof = false then
'-- Open a form/select tag
'-- This particular example has no action attribute, which would normally...
'-- ...be required in order to post the data to another page for processing.
Response.Write ""
Response.Write "" & vbCrLf
Response.Write "Choose...."
'-- loop and build each database entry as a selectable option
While r.EOF = false
Response.Write ""
_ & r.Fields("Title").Value & "" & vbCrLf
'-- Move recordset to the next value
r.movenext
Wend
end if
'--END OF MAIN CODE BLOCK
'-- close select/form tags
Response. Write "" & vbCrLf
End Sub
%>

Dynamic dropdown lists using Active Server Pages and Microsoft Access
Below is an example of a drop down list, dynamically populated from
a database table.
<%
' -- Call the sub procedure to build the drop down list, with the connection
and recordset objects and the source table (In quotes).
call showDropDownList(objConn, objRS, "tblDropDownTest")
%>

Shouldn't it say "if r.eof = false then"?

Thatz what I said on there.If rs.EOF then
Unless there is someother rs.EOF that I forgot to change.But ive done that already and nothing.

After Set r = c.Execute(strSQL) put r.MoveFirst. I seem to remember that there are some circumstances where you have to do this - although it's been a very long time since I've done ASP coding.
Plus, as was said above - it should be If r.EOF = False Then ...

her is a simplified version of my problem...
2 tables...
CUSTOMER
customerId
...
ORDER
orderId
customerId
...
the relationship is clearly one (customer) to many (order)
i want to do a join which will only bring back firt order found.
so
select * from customer
inner join order on order.customerId = customer.customerId
but in my "bigger" query this brings back all orders for each customer. so do any outer joins.
IDEAS?
Thanks in advance

You could always try this:
select * from customer
inner join order a on a.customerId = customer.customerId
and a.orderId = (SELECT First 1 b.orderID FROM order b WHERE b.customerID = customer.customerId) It's not going to be the most efficient SQL ever, but it should do the trick.
|
|
|
|
|
i will try something like that... i think that it will make a difference in speed but the overall query i'm working on returns 100,000+ rows so i'll have to just try and find out. cheers.

Rename your ORDER table to ORDERS since ORDER is a keyword (ORDER BY) that conflicts. I also took the liberty of renaming CUSTOMER to CUSTOMERS (since all table names should probably reflect a "plural" sense).
The key is to form a "virtual" orders table that only contains the first order for each customer, and then join it to the CUSTOMERS INNER JOIN ORDERS table to get the other fields you want while eliminating records you don't want. Using the vendor-specific TOP keyword should work, but a more standard SQL way might be:
SELECT *
FROM (ORDERS AS O
INNER JOIN CUSTOMERS AS C ON O.customerId = C.customerId)
INNER JOIN (SELECT customerId, MIN(orderId) AS M
FROM ORDERS
GROUP BY customerId) AS GB ON O.orderId = GB.M;
Assuming your orderId is incresing, this will give it to you. The GROUP BY is how to eliminate all the rows you don't want. HOWEVER, you'll notice that the output reproduces O.customerId, C.customerId, and GB.customerId, all of which are redundant. The only way I know to preventing listing them all is to spell-out the fields you want instead of using '*'.
Hope this helps.

Thats great. Don't worry about the table names - they were hyperthetical - trust me postng the actual query wouldnt have provoked any response it's huge.

Hi,
I have a problem with a query on a locked table.
The Database I use is mySQL and I want to get a exception when the program try's
to execute a query on a locked table. I tried to set the CommandTimeout in the
OdbcCommand-Object and I also tried to set the "innodb lock wait timeout"-Attribut
from MysQL but it doesn't work.
Has anybody an idea..?

Have you figured out the problem?

Hi,
not realy... I've found an ugly workaround but that was not what
I'm searching for. In other Database Management Systems is something
like LOCK NOWAIT.
Do you have any idea?
Thanks

Please suggest.
Thanks in advance

I am getting the data from database as usual in to a recordset.
I am having some data in array.I want to put the data back in some form in to a recordset so that the existing functionlity does not change.
Remark: The recordset has to be disconnected and database need not be updated.
It is just the calculation that I want to do on the recordset.
Please suggest.
Thanks and regards,
Anil

Just insert the individual elements of the array into the record set. The recordset class should have an Add method to allow you to add the new data into the recordset. I hope this sheds some light for you.

In my case I want to get all rows from a table (however it could be the case I [or someone else] only want to get a specific few). How would I count how many rows have been effected by the SQL query?
Heres a bit of my code:
private const string sqlGetAll =
"SELECT ID , Name , PortalMarkupFile AS Portal " +
"FROM Swin_Devices";
command = new SqlCommand(sqlGetAll, connection);
SqlDataReader reader = command.ExecuteReader();
So I'd like something like reader.getAffectedRows or something similar?
Thanks in advance,
Pete

When you are just selecting data none of the rows get affected. Why don't you use sql Count function?
