Problem in Returning Recordset in ASP

[vinodkus]

I M BEGINNER IN ASP

Please stop shouting.

I WANT TO RETURN TOTAL RECORDS FROM A TABLE.
THERE ARE TWO FORMS CLASS1.ASP AND CLASS2.ASP

Total records?? I think (hope) you mean "count of the total records".
In
ASP, unless you have some means to limit the number of rows in a
table, you
should never be thinking about retrieving all the records in a table.
Always
use a WHERE clause to limit your results. If that is not possible, use
the
TOP n operator.

THROUGH FIRST FORM I JUST POST THE NAME OF TABLE
SO I M WRITING THE CODE OF CLASS2.ASP


dim rs,rs1

class AddNum

public function showRecordCount()
tbl = Request.Form("txtTbl")
rs = con.execute("select count(*) from "&tbl)

You are missing the "Set" keyword here - you are dealing with an
object
variable, not scalar.

end function

What is this function supposed to do? Simply open the recordset and
assign
it to the global rs variable? If so, why use a function? A sub would
be more
suited for this given that you aren't returning any values from the
procedure.

public function returnRS
tbl = Request.Form("txtTbl")
rs1 = con.execute("select * from "&tbl)

Again, you are missing the "Set" keyword here - you are dealing with
an
object variable, not scalar.

end function

Again, a function that does not return anything! This is bizarre.
Also, the
misguided use of selstar! ALWAYS (my turn to shoult) specify the names
of
the fields you wish to retrieve. http://www.aspfaq.com/show.asp?id=2096

end class

dim obj
set obj = new AddNum



Response.write ("Total Record is " & rs(0))



<%
obj.returnRS
if not rs1.eof then '/*********LINE NO 66 *****************/


MY ERROR IS
Error Type:
Microsoft VBScript runtime (0x800A01B6)
Object doesn't support this property or method: 'eof'
/vkasp/aspClass/class2.asp, line 66

BUT WHEN I COMMENT THE IF AND WHILE LOOP PROCEDURE IT GIVES THE FIRST
RECORD

Really? I'm amazed. Without the Set keyword, rs1 should not even be a
recordset. Here is how I would recode this class (I would be passing
the
list of field names for the select clause but I won't get into that).

<%
dim rs, sTbl
sTbl=Request.Form("txtTbl") 'only access collections once


class AddNum


public function showRecordCount(con, tbl)
dim rsLocal, sql
sql="select count(*) from " & tbl
set rsLocal= con.execute(sql,,1)
showRecordCount = rsLocal(0)
rsLocal.close
end function


public function returnRS(con, tbl)


dim sql
sql="select * from " & tbl
Set returnRS = con.execute(sql,,1)
end function


end class


dim obj
set obj = new AddNum


Response.write("<br>")


Response.write "Total Record is " & _
obj.showRecordCount(con,sTbl)


Set rs = obj.returnRS(con, sTbl)
'The IF statement is not necessary since you are not
'doing anything (it seems) if EOF is true


Do Until rs.EOF
...
Loop
%>

You are going to have to determine the guilty line of code by commenting
statements until the code runs without error. Then tell us which line of
code causes the problem.
