Try this with and without the Declare/Fetch option checked. Also this may be a situation where you may have an index on your varchar field, yet Access doesn't know about it. Also what datatype does Access think the field is? I have run into problems where Access will think the text datatype is a Memo field (FAQ 6.5 & 6.6). While on the subject of Access being weird is either your index field or the codelocalite field declared as int8(bigint)?
