Are you using DatabaseLink for this? If so, perhaps simply wrap your Mathematica expression in DatabaseLink's SQLExp function. If there are evaluable expressions in your list then you may want to wrap it in Hold as well in the form SQLExp[Hold[your stuff....]] ?? SQLExpr SQLExpr[ expr] allows a Mathematica expression to be stored in a database. >> --David http://scientificarts.com/worklife On Jan 6, 5:58 am, Chris Degnen <deg... at cwgsy.net> wrote: > Hi.
