سلام :
دوستان چگونه ميشود تعداد record هاي ثبت شده در يك ديتابيس را بدست آورد.
table اين ديتابيس داراي ستون id ميباشد كه بعد از اضافه شدن هر record يكي اضافه ميشود.
نرم افزاري كه اين ديتابيس با آن ساخته شده webmatrix ميباشد كه بانك اطلاعات آن با sql كار ميكند.

قبلا از همكاري شما بسيار سپاسگزارم.

سلام

اين هم يه نمونه برنامه ، به دستور Response.Write rsCount.RecordCount دقت كنيد.

کد:
<%
' BEGIN CONSTANT DEFINITION

	' The following command includes the ADODB VBScript constants file.
	' If you can't find your copy you can download a copy from:
	' http://www.asp101.com/samples/download/adovbs.inc
	' It may not be the most recent copy so use it at your own risk.

	%>
	<!-- #INCLUDE FILE="./download/adovbs.inc" -->
	<%

	' DB Configuration variables
	' After this, strictly used as if it were a Const.
	Dim DB_CONNSTRING
	DB_CONNSTRING = "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.Mappath("./db_scratch.mdb") & ";"

	' Now we override the above setting so the sample uses our SQL server.
	' Comment out the following line to use the sample Access DB.
	DB_CONNSTRING = "Provider=SQLOLEDB;Data Source=10.2.1.214;" _
		& "Initial Catalog=samples;User Id=samples;Password=password;" _
		& "Connect Timeout=15;Network Library=dbmssocn;"

' END CONSTANT DEFINITION
%>

<%
Dim rsCount ' The recordset object

' Create an instance of an ADO Recordset
Set rsCount = Server.CreateObject("ADODB.Recordset")

' Open RS
' I'm actually doing this directly (without a connection object) to keep
' the code short and to the point.  I'm opening the RS with a static
' cursor, read only, and telling it that "scratch" is a table name and
' not a SQL command.  If I don't specify how to open the rs, I'd get the
' default cursor type which doesn't support .RecordCount!
rsCount.Open "scratch", DB_CONNSTRING, adOpenStatic, adLockReadOnly, adCmdTable

' Show RecordCount
' I dress it up and pop it into the middle of a sentence, but you can
' do whatever you want with it.
Response.Write "<p>This table currently has <strong><font color=""#FF0000"">"
Response.Write rsCount.RecordCount ' This is the line that does it!
Response.Write "</font></strong> records in it!</p>" & vbCrLf


'======================================================================
' BEGIN TABLE DISPLAY
' Now I'm going to display the table if they requested it just so you
' have something to look at!  This really doesn't pertain to the topic
' of this sample so I'm going to keep the code short but feel free to
' look it over and if you do please notice the pretty HTML it outputs!
' Ugly HTML output is a pet peeve of mine!  ;)
If LCase(Request.QueryString("showtable")) = "true" Then
	Dim Field   ' Field Looper for display
	Dim bColor  ' Use for showing alternating colors
	bColor = False

	Response.Write "<p>They are:</p>" & vbCrLf

	' Start the table
	Response.Write "<table border=""1"">" & vbCrLf

	' Write Titles
	Response.Write vbTab & "<tr>" & vbCrLf
	For Each Field in rsCount.Fields
		Response.Write vbTab & vbTab & "<td bgcolor=""#CCCCCC""><strong>" & Field.Name & "</strong></td>" & vbCrLf
	Next 'Field
	Response.Write vbTab & "</tr>" & vbCrLf

	' Loop through records outputting data
	Do While Not rsCount.EOF
		Response.Write vbTab & "<tr>" & vbCrLf
		For Each Field in rsCount.Fields
			Response.Write vbTab & vbTab & "<td bgcolor="""

	Loop

	' End the table

Else
	Response.Write "<p><a href=""db_count.asp?showtable=true"">Show the table</a></p>" & vbCrLf
