How to insert data into a database with ASP

[jhardman]

step 1- get data.

for example, make a form with one input field for each piece of data you want to put in the db:[html]<form method="post" action="thisSam ePage.asp">
<input type="text" name="userName" >User Name<br>
<input type="text" name="phonNumbe r">Phone Number<br>
<input type="text" name="toothBrus hColor">Color of your Toothbrush<br>
<input type="submit" value="submit"> </form>[/html]
For convenience, it helps to make the name of the input identical to the name of the fields of the database.

It is a good idea to make sure you got data at this point, so list it like this:

dim x
for each x in request.form
   response.write x & ": " & request(x) & "<br>" & vbNewLine
next

you got data? good.

step 2- connect to the database.

Unfortunately, ability to connect to a db is not built directly into aspwhen it was originally made, but it was added later in the form of a series of server objects. It is a bit awkward and that is just the way it goes. The connection looks like this:

dim objConn, objRS
set objConn = server.createObject("adodb.connection")
objConn.Provider="Microsoft.Jet.OLEDB.4.0"
objConn.Open "c:/inetpub/myDBFiles/myDBofUsers.mdb"

step 3- There are several ways to work with the db once you are connected. I prefer to do it by creating a recordset like this:

dim query
set objRS = server.creatObject("adodb.recordset")
query = "SELECT * FROM userTable"
objRS.open query, objConn

This gives you an object named "objRS" which is a little copy of one table of the db.

step 4- To add a new record, do this:

objRS.addNew
objRS("userName") = request("userName")
objRS("phonNumber") = request("phonNumber")
objRS("toothBrushColor") = request("toothBrushColor")
objRS.update

Now you have added data to a db. That wasn't so hard, was it?

Jared

PS Remember how I said it was convenient to use the exact db field names as the name of your form inputs? If you did this, then step four can be simplified to this:

dim x
objRS.addNew
for each x in objRS.fields
   if request.form(x) <> "" then
      objRS(x) = request.form(x)
   end if
next
objRS.update

This opens the db and goes through each field and looks for a form input with the same name. If it finds one, that input is used to populate the corresponding db field.

how to connect if you're using c#

how to connect if you're using c#

You can't write ASP pages in c#, so your question is meaningless (or it would be meaningless if you had written a question). Try the .NET forum.

as i was looking through the questions and articles i came by ur article sir iam also using the same thing or say the same way to insert in to a data base but if i use the objrs.AddNew after i open query and conn it adds the record twice means each input in the form that i submit is entered twice .....and if i dont use the objrs.AddNew then it edits the very first record in the data base means it overwrites the 1st record in the table :( y is that so for ur convienience i am writing the code here, and yes one thing also if i exit the editor(dreamwer aver)
and explorer windows OR if i edit the code and then save it without any query that gives error and then again write the same query then the first time it enters only once but as i continue to enter the data through the form it tarts adding the record twice again can u help in the matter

I don't see anything in this code to suggest why that might happen. Are you doing anything to monitor or kill double-posts?

[omerbutt]

no nothing like that is happening ......... :) ...but infact yesterday i found the mistake that fixed the problem the mistake don looks like a mistake to me ......well u r gonna decide .....
the form through which i was submitting my data used a button that called a javascript function in which i validate
Addstk()---->that stands for add stock
in the funtion i am applying constraints and check for empty input lemme show u the code that i was using before then i wil tell u a lil change that i made or was that a mistake...

function Addstk()
{
                var flg;        
    var str;
    str += "Please Fill in the following";
    str += "\n**************";
 
    if((document.forms[0].code_no.value)=="")
    {

    if((document.forms[0].unit_price.value)=="")
    {

        flg = 0;
    }
    if((document.forms[0].size.value)=="none")
    {

    }
    if(flg == 0)
    {
        alert(str);
        return false;
    }
    else
    {
                    ducument.forms[0].action="adstk_done.asp";
                                document.forms[0].submit();
                     return true;
    }
 
}
 

and the form tag was like this

<HTML>
<form name="addstkfrm"  method="post">
</HTML>.
 

note the last very last else

And what i did was i removed these 2 lines

document.forms[0].action()="adstk_done.asp";
document.forms[0].submit();
 

and added the action property in the form tag and the specified the same file that i was using to submit in the js function given above

<form name="adstkfrm" method="post" action="adstk_done.asp">
 

wasnt that stupid :D i don know weather its a logical mistake by me or abnormal behaviour of the application u temme and with this i have made more than 50 entries and none them were duplicated

Yes, I'm not a javascript expert, but it appears the mistake was in the line which says to re-submit the form, it was already submitted, you don't have to submit it again, I think the way you handled it is preferred. The form is supposed to have all those attributes. If you decide to set those attributes with javascript you should have a very good reason for doing so.

Jared

PS, Please stop writing in slang. This is an international site and it is very difficult for many readers to understand when you use "u temme" or "u r gonna" or similar incorrect English. I personally find it very annoying. I had to stop myself from insulting you just now.

[omerbutt]

yeah obviously you are right
and yes sori about that slang you know while writing it looks a little quick and easy thats why ....anyways i wud watch that next time

[chirag1989]

one should specify the lock type as default lock type doesnt support inserting data into database using record set object

Thanks, I didn't notice that I had left that out.
