Re: Ctrl+F in MsAccess table is very slow

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)?
