Clustered index question

Hello, We have a table with an index "i_abcd" on an integer column. I changed it to clustered index using alter index statement. It turned out that this column has a referential constraint (This I didnot see before). Now I want change it back to non clustered index. The name of this index is changed to " 336_226" and alter index is not working. How do I do this ? What happens if I drop theconstraint and add an index i_abcd and put the constraints back on ? Another thing is that I see 336_226 name using dbaccess->info->index. But when I do a dbschema on the table, it says 128_226 (not 336_226) on this column. Can anyone comment on this - what do I need to do to change it back to non clustered index ? Thanks Keith
