Need help With this error.

hi guys
Recently i have been given a task to debug a website survey system. The problem is whenever user tried to submit there i will be a error saying

Quote:

No value give for one or more required parameter

I am very very new to asp and in fact this is the first time i come in contact with asp. Was doing jsp previously this is for one of my final year project. Would apperciate if anyone could help :)

This is the code....

Quote:

<%Option Explicit%>

<%
dim conn, rs, strsql, x
dim updateOK
dim update_survey_status
dim i
dim array_result()

set conn = server.CreateObject ("ADODB.Connection")
conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & server.MapPath ("mentorDB.mdb")
set rs = server.CreateObject ("ADODB.Recordset")

strsql = "SELECT * FROM " & survey_result_table

for i = 0 to 12
redim preserve array_result(i)
array_result(i) = "Q" & i+1
next

rs.open strsql, conn, 1

strsql = "UPDATE [" & survey_result_table & "] SET "
for i = lbound(array_result) to ubound(array_result)
if i <> ubound(array_result) then
strsql = strsql & array_result(i) & "='" & request.form(array_result(i)) & "',"
elseif i = ubound(array_result) then
strsql = strsql & array_result(i) & "='" & request.form(array_result(i)) & "'"
end if
next
strsql = strsql & " WHERE ADM='" & Session("ParseAdm_No") & "'"

on error resume next
conn.execute strsql

if err<>0 then 'if have errors
updateOK = false

response.write("<script language = 'javascript'> alert('" & err.Description & "'); </script>")

else 'If no errors
updateOK = true
end if

if updateOK = true then
strsql = "UPDATE [" & left(trim(Session("ParsePem_Gpr")),2) & "] SET SURVEY_DONE=TRUE WHERE ADM='" & Session("ParseAdm_No") & "'"

on error resume next
conn.execute strsql

if err<>0 then 'if have errors
update_survey_status = false

else 'If no errors
update_survey_status = true
end if
end if

rs.close
conn.close
set rs=nothing
set conn=nothing

if updateOK = true and update_survey_status = true then

response.redirect("http://localhost/night/thanks.asp")

elseif updateOK = false or update_survey_status = false then
response.write("Update failed. Please contact administrator.")

end if

baby

it didnt state, but i tried line by line shifting down the pop up of the error it should be at the first update function..... hope you can help :) and if theres anyway that i can show what line is the error pls let me know

test for errors after any piece of code that might fail, something like this:

VB Code:

<%Option Explicit%>
<!--#include file="includes/config.asp" -->
<%
dim conn, rs, strsql, x
dim updateOK
dim update_survey_status
dim i
dim array_result()
 
On Error Resume Next
 
updateOk = true
update_survey_status = true
 
set conn = server.CreateObject ("ADODB.Connection") 
conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & server.MapPath ("mentorDB.mdb")
If Err.number <> 0 Then
    Response.Write("Error opening connection...<br/>")
    Response.Write("Error: " & Err.number & "<br/>" & "Desc: " + Err.Description)
    Response.End
End If
 
 
 
strsql = "SELECT * FROM " & survey_result_table
 
for i = 0 to 12
    redim preserve array_result(i)
    array_result(i) = "Q" & i+1
next
 
set rs = server.CreateObject ("ADODB.Recordset") 
rs.open strsql, conn, 1
If Err.number <> 0 Then
    Response.Write("Error opening recordset...<br/>")
    Response.Write("SQL: " & strsql & "<br/>")
    Response.Write("Error: " & Err.number & "<br/>" & "Desc: " + Err.Description)
    Response.End 
End If
 
strsql = "UPDATE [" & survey_result_table & "] SET "
for i = lbound(array_result) to ubound(array_result)
    if i <> ubound(array_result) then
        strsql = strsql & array_result(i) & "='" & request.form(array_result(i)) & "',"
    elseif i = ubound(array_result) then
        strsql = strsql & array_result(i) & "='" & request.form(array_result(i)) & "'"
    end if
next
strsql = strsql & " WHERE ADM='" & Session("ParseAdm_No") & "'"
 
conn.execute strsql
If Err.number <> 0 Then
    Response.Write("Error executing sql...<br/>")
    Response.Write("SQL: " & strsql & "<br/>")
    Response.Write("Error: " & Err.number & "<br/>" & "Desc: " + Err.Description)
    Response.End 
End If
 
if updateOK = true then
    strsql = "UPDATE [" & left(trim(Session("ParsePem_Gpr")),2) & "] SET SURVEY_DONE=TRUE WHERE ADM='" & Session("ParseAdm_No") & "'"
 
    conn.execute strsql
    If Err.number <> 0 Then
        Response.Write("Error executing sql...<br/>")
        Response.Write("SQL: " & strsql & "<br/>")
        Response.Write("Error: " & Err.number & "<br/>" & "Desc: " + Err.Description)
        Response.End 
    End If 
end if
 
rs.close
conn.close
set rs=nothing
set conn=nothing
 
if updateOK = true and update_survey_status = true then
    response.redirect("http://localhost/night/thanks.asp")
elseif updateOK = false or update_survey_status = false then
    response.write("Update failed. Please contact administrator.")
end if

the error is still the same =( can anyone help ? and see if the coding is correct =)

that code wasn't supposed to fix anything, it was supposed to help you figure out where and maybe why the error is happening. Did you figure out at least where the error is occurring? if not, post the code you're using to figure out where the error is occurring.

It happen during the first update function...

So did you print out the SQL and try to figure out why or if the sql is the problem?(it probably is the probem, you need to print that sql out to the screen or somewhere and see why it's the problem)
Dec 22nd, 2003, 09:34 AM

um.. the error i get is No value give for one or more required parameter.. I wonder what that means

post the sql it's trying to run.

Quote:

strsql = "UPDATE [" & survey_result_table & "] SET "
for i = lbound(array_result) to ubound(array_result)
if i <> ubound(array_result) then
strsql = strsql & array_result(i) & "='" & request.form(array_result(i)) & "',"
elseif i = ubound(array_result) then
strsql = strsql & array_result(i) & "='" & request.form(array_result(i)) & "'"
end if
next
strsql = strsql & " WHERE ADM='" & Session("ParseAdm_No") & "'"

on error resume next
conn.execute strsql

if err<>0 then 'if have errors
updateOK = false

That's the code that generates the sql, print out the actual SQL it's trying to run. so right after the line:
VB Code:
conn.execute strsql
put this:
VB Code:
If Err.number <> 0 Then
  Response.Write("Error: " & Err.number & "<br/>")
  Response.Write("Desc: " & Err.description & "<br/>")
  Response.Write("SQL:<br/>")
  Response.Write(strsql)
  Response.End
End If
and then post what the actual sql code is.

ok got it

Quote:

Error: -2147217904
Desc: No value given for one or more required parameters.
SQL:
UPDATE [Survey_Result] SET Q1='3',Q2='3',Q3='3',Q4='1',Q5='4',Q6='4',Q7='4',Q8='4',Q9='4',Q10='1',Q11='1',Q12='1',Q13='1' WHERE ADM='000577U'

Can you run that query successfully against the database? maybe make sure there are columns Q1 through Q13 for that particular survey. I've seen some other posts where users experienced the same error message when they really had a type mismatch. After verifying that all of the columns exist(Q1 through Q13) check their datatypes. If they're numeric you're gonna wann take off the single ticks(apostraphe's) in your update, so it'd look something like:

PHP Code:

UPDATE Whatever SET Q1=3, Q2=4 ...

oh, and you don't do anything with that recordset rs, it's in this snippet:
VB Code:
```
strsql = "SELECT * FROM " & survey_result_table
 
for i = 0 to 12
    redim preserve array_result(i)
    array_result(i) = "Q" & i+1
next
 
set rs = server.CreateObject ("ADODB.Recordset") 
rs.open strsql, conn, 1
```
It doesn't appear to be used for anything, if that's true, get rid of it, just more moving pieces in the way of figuring out what's wrong(leave the for..next loop just get rid of the recordset part).
