Обсуждение: upgrade problem with driver postgresql-8.1-407.jdbc3.jar
Hi all, I'm running into this problem when upgrading my jdbc driver from pg74.216.jdbc3.jar to postgresql-8.1-407.jdbc3.jar I started having syntax error with the new driver and cannot find where is the problem. Here is the log: 2006-09-06 09:48:20 LOG: statement: PREPARE <unnamed> AS COPY vd (VDVSSRC, VDVSNUM, VDKEY, VDDATA) FROM $1 2006-09-06 09:48:20 ERROR: syntax error at or near "$1" at character 66 2006-09-06 09:48:20 STATEMENT: COPY vd (VDVSSRC, VDVSNUM, VDKEY, VDDATA) FROM $1 Here is the VARCHAR given for $1: c:\\temp\\webCatalog\\20060517030156.zip20060517030156.zip20060517030156.zip If I try the corresponding command in pgAdmin3 it works well... Any idea what is the error? Which I suspect is quite evident .. :-/ Thanks for the help! Best Regards /David
David, The driver has no idea how to deal with a $, It also uses prepared statements if you use the preparedStatement interface.

You will have to construct the query by hand yourself rather than using ?. -O
Is that a bug then since this way working with the 7.4 jdbc driver ? Any idea why it stops working ? Thanks for the help!

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
