 Re: upgrade problem with driver postgresql-8.1-407.jdbc3.jar David Gagnon wrote: > Is that a bug then since this way working with the 7.4 jdbc driver ? It's not really a bug, it's that the driver is now more picky about where parameters may be placed in the query. You were never really meant to put parameters just anywhere in a query, it just happened to work in the past. > Any idea why it stops working ? The older driver you used did literal substitution of parameter values into the query. Newer drivers turn ? placeholders into $n placeholders and pass the actual parameter values separately to the query string. So they only allow ? placeholders where a $n placeholder is accepted by the server. -O ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster      |
