@Remou on DHookom's Concatenate function: neither the SQL standard nor the Jet has a CONCATENATE() set function. Simply put, this is because it is a violation of 1NF. I'd prefer to do this on the application side rather than try to force SQL to do something it wasn't designed to do. Perhaps ACE's (Access2007) multi-valued types is a better fit: still NFNF but at least there is engine-level support. Remember, the question relates to a stored object: how would a user query a non-scalar column using SQL...?

@David W. Fenton on whether Jet has stored procedures: didn't you and I discuss this in the newsgroups a couple of years ago. Since version 4.0, Jet/ACE has supported the following syntax in ANSI-92 Query Mode:

CREATE PROCEDURE procedure (param1 datatype[, param2 datatype][, ...]) AS sqlstatement;

EXECUTE procedure [param1[, param2[, ...]];

So Jet is creating and executing something it knows (in one mode at least) as a 'procedure' that is 'stored' in the MDB file. However, Jet/ACE SQL is pure and simple: it has no control-of-flow syntax and a PROCEDURE can only contain one SQL statement, so any procedural code is out of the question. Therefore, the answer to whether Jet has stored procedures is subjective.
