Is There An Easy Way To Prevent Duplicate Records Being Added To A Access DB

I am adding simple records to a fairly simple access database with the following code

rsEntry.Fields("Player1") = ShortName(Player1)
rsEntry.Fields("Player2") = ShortName(Player2)

'Write the updated recordset to the database
rsEntry.Update
rsEntry.Close
adoCon.Close
Set rsEntry = Nothing
Set adoCon = Nothing

How can I SIMPLY :-) prevent duplicate records from being added? I know I can set the index property on the fields but that mean handling the errors - not sure how to do this.
OR I could write the code to seach the DB before update - which may be the only way :-(

Is there a simple way?

Prevent The Duplicate Value

i have a form by asp and database by MS access.so i want to prevent the duplicate value in empID because when i add a new employee with the same id ASP gives me this error.

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC Microsoft Access Driver] The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again.
/employee/admin/addemp1.asp, line 48

so i want the employee to get a message like this empID already exist or somthing like this.

Prevent Duplicate Submissions

I need help ASAP. I have a form where users can fill out the fields firstname, lastname, and emailaddress. When the user submits the form, I need ASP to call out to a SQL Server database to see if the firstname, lastname and emailaddress the user submitted already exists in the database.

If they all do exist, the user should not be allowed to submit the data but should be redirected to a page saying "sorry, you have already entered that information" or something to that effect.

Duplicate SQL Records Created ?

I am trying to do a simple INSERT into SQL. I've done it tons of times before with the same code, but this time is is placing duplicate entries in the table. Any ideas why this would be happening? Here is my ASP code doing the form processing:

<%
set conn=server.createobject("adodb.connection")
conn.Open "Driver={SQL Server}; Server=SERVERNAME; Database=DATABASENAME; UID=USER; PWD=PASSWORD"
set rs = Server.CreateObject("ADODB.RecordSet")

strTitle = Replace(request.Form("title"), "'", "&#39")
strContent = Replace(request.Form("txtContent"), "'", "&#39")

strSQL = "INSERT INTO [webPages] ([created], [section], [title], [content]) Values ('" & now() & "','" & request.Form("section") & "','" & strTitle & "','" & strContent & "')"
rs.Open strSQL, conn, 3

Content Not Being Added

I'm a designer by trade but the company I work for does asp via the built in Dreamweaver stuff. I've ran into this problem before and now twice this week. I can't remember how ai fixed it first time and actually think it was just down to luck rather than knowledge.

I can retrieve the data out of the database table and delete it but when I try to add it from the admin form or modify it (i'm passing the variale fine as its fills the form in with all the relevant values) the page refreshes without adding the content or modifying the content. As I say I'm not writing the code but generating it via dreamweaver so don't really understand whats wrong.

Insert Records Access DB

Anyone know if it is possible to update/insert a database record into a dynamically specified field.

The code I have here holds data in an asp session, ownerId, storeid and product type.

I can insert a record into the Productcat table, fields OwnerId and surfboards, no problem.
But what I would like is to insert the ownerid then insert poduct type into the field sepcified in the session variable (session("prodtype")) and/or strprodtpye

For Example
Insert OwnerId + product type into productcat into fileds ownerId and field labled ''strprodtype'' (variable, surfboard, wetsuit, boots, etc)

SQLstatement = "INSERT INTO Productcat (Ownerid,'"&strprodtype&"') "

I have tried using different methods, but the closest I got was IIS error msg ='field not found ("Surfboards", "wetsuits", "boots", etc)' Code:

Paging Access DB Records

I am trying to provide a paged listing of Access DB table data using ADO. I have a problem using the AbsolutePage method. I am using the following:

[VBS]
objRs.Open strSQL, objDbConn, adOpenStatic, adLockReadOnly, adCmdText
objRs.PageSize = 5
objRs.CacheSize = 5
objRs.MoveFirst
objRs.AbsolutePage = 24
Response.Write(objRs.AbsolutePage)
Do While objRs.AbsolutePage = 24 And Not objPubRs.EOF
Response.Write(objRs("data"))
objRs.MoveNext
Loop
[/VBS]

The line "Response.Write(objRs.AbsolutePage)" writes "-1" and the loop does not write any data.

If I remove the "objRs.AbsolutePage = 24 And" from the loop test it will write recordset data starting with the proper page position but continues to the end of the recordset (including all following pages).

With objRs.AbsolutePage reporting -1 I cannot test out of the loop based on the recordset page number.

Merge To Records In Access

1 0001 T-Shirt Black 5
2 0002 Soccer Ball Red 1
3 0001 T-Shirt Black 2
4 0001 T-Shirt Navy 6

What I need to do using ASP is take record 1 and merge it with record 3. By this I mean I need to show only a singular qty for the product code 0001.

i.e.

ID Code Description Colour Qty
1 0001 T-Shirt Black 7
2 0002 Soccer Ball Red 1

Format Records From Access Database

I have an access db from which I would like to display records in a formatted manner. I can display all the records one after the other on one page no problem, but I would like to display maybe 6 records on one page (3 across, 2 down). I would then need a page break for printing purposes.

Displaying all the records on one page would be fine if I can put a page break in so that they print correctly. I currently have it fomatted correctly, but my loop is not working correctly. Instead of different records displaying, I have 6 of the same record displaying, then the next record displaying 6 times, etc.

Even if it's better to do this over multiple pages, that would be fine as long as I can print the report with all records by clicking Print only once. Maybe even display the records on multiple pages with next and previous buttons, but when the user clicks print, then it would print a report from access.

I hope this all makes sense. Does anyone have any ideas or suggestions or pointers on the best way to do this both for viewing and printing purposes? Code:

Carriage Return Being Strangely Added When I Perform A Standard Post

I am performing a post from one classic ASP page to another in order to get the value of a string passed between the two pages. I have a client script variable declared to take the value of the value being received in the page i.e. var x = '<%=varName%>'. Unfortunately, ASP seems to be adding a carriage return to the value of varName when it
is passed in i.e. it expands the stated line to var x = 'FieldContents';. I.e. somewhere a carriage return has been added. The string gets passed in OK if I use the Get mechanism. Don't know why this carriage return is being added when using Post mechanism. Anybody seen this before? Is it a bug in ASP ?
