[Zope] Inserting LONGs with DCOracle

Hi, If I try to insert an ca.5000 char string with DCOracle(1.3.2) into a LONG column in Oracle (8i) I keep getting ORA-1704 'string literal too long'-Errors. Ok, I read here http://osi.oracle.com/~tkyte/Misc/LargeStrings.html that it will work (a) with bind variables or (b) that I have to use ODBC,OCI or alike. Questions: (a) Can I use bind variables with DCOracle? How? (b) I thought DCOracle is using OCI, so why the heck this isn't working? Any workarounds? thanks for help, dekay
