Cryptic error message - need help tracking it down!

I'm getting a very cryptic error message from ADO (running through ASP):

Quote:

---

Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.

---

If occurs halfway through adding a record or updating an existing one.

I just can't for the life of me work out what the error is trying to tell me. I've looked through the connection, recordset and error objects' errors collection but they only contain the message above. Does anyone know how to "Check each OLE DB status value"?

For what it's worth the code is as follows, although I don't think the problem is related directly to the code.

Code:

---

oRS.Open "SELECT * FROM Auth WHERE Login_ID='" & sICUser & "';", oConn, adOpenDynamic, adLockOptimistic
               
If oRS.BOF And oRS.EOF Then
        oRS.AddNew
        oRS("Acct_number") = GetLastAcct_Number ' Function to get the next available ID
End If

If sICUser = sUsername Then sICUser = Make_IC_Username
               
oRS("Login_ID") = sICUser
oRS("Password") = sPasswd_1
oRS("Account_Status") = "enabled"
oRS("Service") = sService
oRS("EmailAdd") = sUsername & "@" & sDomain
oRS("Title") = sTitle       
oRS("Firstname") = sFirstname
oRS("Surname") = sSurname
oRS("Dayofbirth") = iDob_Day
oRS("Monthbirth") = iDob_month
oRS("Yearbirth") = iDob_year
oRS("Addressl1") = sAddress_1
oRS("Addressl2") = sAddress_2
oRS("Town") = sTown
oRS("County") = sCounty
oRS("Postcode") = sPostcode
oRS("Telephone") = sTelephone
oRS("CustGender") = sGender
oRS("AccStatus") = "y"
oRS("Mobile") = sMobile
oRS("UseMobile") = bUse_Mobile
oRS("ContactEmail") = sOldUsername & "@" & sDomain
oRS("DateSign") = GetGoodDate ' Function to make a date that the DB likes
oRS("SecurityQU") = sSec_Ques
oRS("SecurityAnswer") = sSec_Answ
oRS("Arts_and_Culture") = "n"
oRS("Automotive") = "n"
oRS("Computing") = "n"
oRS("Education_and_Jobs") = "n"
oRS("Entertainment") = "n"
oRS("Finance") = "n"
oRS("Food_and_Drink") = "n"
oRS("Health_and_Fitness") = "n"
oRS("Home_and_Family") = "n"
oRS("Internet") = "n"
oRS("Kids") = "n"
oRS("Men") = "n"
oRS("News_and_Weather") = "n"
oRS("Recreation") = "n"
oRS("Shopping") = "n"
oRS("Sport") = "n"
oRS("Travel") = "n"
oRS("Women") = "n"
oRS.Update
               
oRS.Close
Set oRS = Nothing

It could possibly be that you are adding a value that's wrong for the underlying datatype of the database field - I've run into that when "normalizing" Access dbs for import into MS SQL. I'm just guessing, though.

Yeah, I read an article somewhere that hinted around that area. It can sometimes occur when trying to stuff a value that is too big for the db field that it's trying to go into.

Which puzzles me more. The error is generated on the line:

Code:

---

oRS("CustGender") = sGender

---

Now CustGender is a varchar(1) and sGender contains either a "m" of an "f". So as I see it I'm trying to put a string of length 1 into a char field.
I've tried using Trim(sGender) but to no avail, and Char(sGender) gives me a type mismatch!!!

Well, you could try peeking at stuff like oRS.Fields("CustGender").Type , etc, and see what ADO thinks it is.
