I am trying to create a parameterized query and it keeps giving me an error "Datatype error in expression" when I enter = @ChildID or =?ChildID. The ? is supposed to be the wildcard for Access SQL.

I am using an Access database that uses an autonumber field as the primary key for a table. The data adapter on the data tier is based on a table called tblChild. The field is ChildID. I'm trying to enter it in the CommandText property of the SelectCommand.

I tried entering info in the criteria for another integer autonumber field and had the same error message.

It appears to work ok in the string fields though.

Is this a problem with autonumber fields in Access being used in VB.net?
Does anyone have any suggestions at all??? If there's a knowledge base
article, please point me to it. I have been unable to find anything.

Thanks!

Hi Donotspam,

You can start here with finding your solution.

http://msdn.microsoft.com/library/de...ClassTopic.asp

Next time you can better ask this in the newsgroup

microsoft.public.dotnet.framework.adonet
and vbnet related
microsoft.public.dotnet.languages.vb

When you think it is both or even to this newsgroup related you can
crosspost, that is sending one message to all subject related groups.

I hope this helps,

Cor

Hi Cor,

I figured it out. I only needed to use ?, rather than include the field name too.
Thanks for tips.

Have a good day.
