BLOBs in blobspaces

I have a database in which is a several dozen tables with such a schema: create table t1 i int, c char(20),some byte in xyzbls ); The BLOBs are located in a special (different) spaces than the rest of the table. I am able to find out how full the xyzbls is. but I would like to know which BLOBs from which table take the most space? Is it possible? ------------------------------ roze ------------------------------ #Informix

Select length(blob) from table Will give you the size of the actual blob
