Orphaned Indexes

Our ‘check indexes’ job was failing occasionally with an error like …

Msg 7999, Level 16, State 40, Line 1 Could not find any index named ‘index_name’ for table ‘table_name’.

I tried to just exclude the named index, but a few days later another one appeared. The fix was to dig into the SP and add a condition to the statement …

insert into #indexlist
            select name
	    from sysindexes
	    where name not like '_WA%'
	    and indid not in (0,255)
	    and [root] is not null
	    and id = @tab_id
