Hi Adam,

> "Does it matter?"

yes it can matter.  I have seen tables display with funky characters when a unique index is not specified ... then remove link, do it again again and specify it correctly and voila!  I guess it has something to do with Access being able to keep track of what is has in memory.

warm regards,

~ have an awesome day ~

This is not unique to Access 2013. I've had it happen to me when linking to a table that doesn't have a primary key defined. I don't know why anyone would do that but sometimes they do. If you can, have a primary key designated on the table and if you can't, then choose a combination of fields that make a record unique.

Does your SQL table have a Primay Key defined or only a unique index?

Why does Access (2013) make me select key fields, when linking to SQL tables, when they are already defined in SQL? Does it matter?
