Question

Error:

Asked by: Greben

I don't get any output from my database.. What's the error?

<%
set cn = server.createobject("ADODB.Connection")

cn.open = "DRIVER={MySql}; SERVER=asdf.asdf.com; DATABASE=asdf; UID=asdf; PWD=asdf"
%>

<%
  sql = "SELECT `id`, `login`, `password` FROM `userbase`"

  set rest = cn.execute(sql)

  while not rest.eof
    response.write ("<br><br>brugernavn" & rest("login") & "<br>password: " & rest("password"))
    rest.moveNext
  wend
%>

<%
  cn.close
  set cn = nothing
%>


I know it's ASP code, but it's probably more a question to MySQL users which also uses MyODBC with some other program. Running the query directly in the server works fine - but not through MyODBC?

According to the following page, you string is correct:
http://www.able-consulting.com/ADO_Conn.htm

Looking here:
http://www.mysql.com/products/myodbc/manual.html#MyODBC_With_VB
If find that the select statement doesn't use the ` to enclose the field names. Maybe try "SELECT * FROM userbase"...

Have you made sure that your connection was successful ?

Have you made sure that your query was correct ?

Have you made sure that there are records in userbase table ?

Please check those things, they might look 'stupid' but sometimes you miss some basic point.

And yeah try not to use back quotes. You need only when you have column name which is keyword in mysql.

First I've tried without backquotes - then I tried to use backquotes because I was told that "id" was a reserved word in myODBC, and finally I tried selecting *

I've tried with three different queries:
sql = "SELECT `id`, `login`, `password` FROM `userbase`"
sql = "SELECT `login`, `password` FROM `userbase`"
sql = "SELECT * FROM `userbase`"

and only the second worked. There were 4 posts in the table. Then I found out that the ID-field was a BIGINT, which didn't work on a Windows 2000 Server, but actually worked fine on a Windows XP. There's a setting in MyODBC where you can set the driver to translate it into the INT instead of BIGINT. That's why it didn't work.

But thanks anyway - just found out - have been looking for the error in 4 days and finally - I found it... And dkjariwala-> That was off course the things I did thirst. The strange thing was that the error only occured when selecting the id-column - that's why I wasn't able to find the error...

 

by: angelIIIPosted on 2002-08-23 at 01:25:46ID: 7237962

Correct me if i'm wrong, but I think it's the BIGINT data type of the ID field, which cannot be "translated" for ADO ... (as described in the doc) ...

angellll-> you're probably right about it, I just found out accidentially.. And the mysql.com faq/manual didn't mention anything about it..

But the Windows XP works with the BIGINT data type. Just not Win2k
