Questions: 1) Is there any way you can easily identify the relevant rows in the legacy database and export only those? 2) If the answer to 1: is "no", then is the legacy database something you could access directly using Perl::DBI, PHP or Python, and dynamically import only the matching rows? -- -Josh Berkus Aglio Database Solutions San Francisco
