Hi Stefan, Replace seqbase(0@0) by tmark(0@0). That one works with constants as well. -----Original Message----- From: Stefan Manegold [mailto:Stefan.Manegold@cwi.nl] Sent: Thursday, December 07, 2006 4:33 PM To: monetdb-developers@lists.sourceforge.net; Peter Boncz Subject: Re: [Monetdb-pf-checkins] pathfinder/compiler/mil milprint_summer.c, 1.298.2.4, 1.298.2.5 Peter, the changes below seem to make 3 of the 6 Music/limit tests fail with " !ERROR: interpret: no matching MIL operator to 'seqbase(int, oid)'. !MAYBE YOU MEAN: ! seqbase(BAT[void,any::1], oid) : BAT[void,any::1] ! seqbase(BAT[void,any::1]) : oid ! seqbase(BAT[oid,any::1]) : oid " What kind of solution/fix do you recommend? (1) set the seqbase only if the type is BAT, or (2) add a "fake" constant-seqbase variant to the constant module ? Thanks! Stefan On Tue, Nov 28, 2006 at 02:18:09PM +0000, Peter Boncz wrote:

we require the seqbase of our iter|pos|item relations to be 0@0
