Problem reading VARCHAR and Text-Fields and ADO

[Boris Wilhelms]

Hello all,

at first, sorry for my bad English, I’ll give my best 

We have a strange problem reading Text- and VarChar-Fields.

Our configuration:
-Windows 2003 Server
-MySQL Server 3.23.36
-MyODBC 3.51
-ASP & ADO

We are querying a database with ADO and store the data in an
ADO-Recordset.
Then, if we read a textfield from the Recordset the first time, we get
back the data, but reading the field a second time, it returns NULL!

Sample Code:

set db = Server.CreateOb ject("ADODB.Con nection")
db.Open "dsn=" & hdbdsn & ";uid="& hdbuid &";pwd=" & hdbpwd & ""
sql = "SELECT * FROM tbl"
Dim rsTeaser set rsTeaser = db.Execute(sql)
Dim a
a = cstr(rsTeaser(" Description"))
Response.Write( "Descriptio n:" & a & "")
Response.Write( "Descriptio n 2: " & rsTeaser("Descr iption ") & "")

Reading rsTeaser(„Besch reibung“) the first time, works
fine. But reading the same field again, we get back NULL.
To access MySQL we’re using MyODBC 3.51 with the default
options.

Hope someone can help us!

Thanks and kindest regards

Boris,

Would that be MySQL Linux?
Do you have any type BigInt key fields?

We have found the MySQL ODBC driver to be quite useless when dealing with a
BigInt key field. The only workaround we have found is avoidance. We don't
use BigInt in MySQL tables. Problems similar to the ones you mention
vanished once we adopted this policy.
