For a MyISAM table (where referential > integrity is not enforced), is this information even retained? Not yet for MyISAM, see http://www.mysql.com/doc/A/N/ANSI_diff_Foreign_Keys.html See also the info about InnoDB, which may do what you want. >From a coder's point of view, I always give such columns a special name so I know it references another table, and perhaps also also which one (and through which column). I think that's good coding practice. This just keeps the situation very clear to me, while coding, without having to look up the table schema or rely on constraints.
