Thanks, Art. There was one blade registered - namely bts.3.00 . I don't know how it got registered. I did not do it. Nobody else has access. I unregistered it. That reduced the number of lines of junk...

It's been a long time since I've used HDR with Informix 10. It went out of continuing support in 2013. The BTScanner could be a factor in poor performance with the deletes. Was the database logged...

It could have been auto registered ?? Try removing/renaming the files in $INFORMIXDIR/extend ? These,AFAIK, are all to do with the blademgr, so in theory you can run remove them from the SQL. Cheers...

It can auto register itself if someone with sufficient privileges called a BTS function. You will have to drop the objects that the BTS blade created. That would include the CASTs, PROCEDURES, types...

Two quick questions. I believe in the select statement you might need to prepend the table name to the column named "current". As current is a reserved word and the parser will not understand if you...
