Hi all,
whe I create a new materialized view with "build deferred" and "using trusted constraints", the script shows up in the schema browser without trusted constraints until it has been refreshed.
Best regards from Germany

HI Rainer,
I just tested this and can reproduce it. The value that Toad uses for "using trusted constraints" is when dba_mviews.unknown_trusted_fd = Y. You can see it's N before a refresh and Y after.
I'll look for somewhere else to get that info. If you know of another place, please let me know.
Edit: I see I can use SYS.SNAP$.FLAG2, if you have privs. Those kinds of fields are always tricky though.

Hi John,
I feared that the information comes from the flag UNKNOWN_TRUSTED_FD... That's why I put a question mark in the subject of my new topic. You are right, before refresh it has the value N, which is an Oracle bug for me. I did some Google research, but I found no better place to get the info about the trusted constraints.
If you can do anything using SYS.SNAP$.FLAG2 (I don't know anything about that stuff) - very good. If not, it does not matter...

Hi Rainer,
This query seems to return the correct value both before and after the refresh. Can you confirm?
select sowner, vname, decode(bitand(s.flag2, 65536), 65536, 'Y', 'N') using_trusted_constraints from sys.snap$ s
John, I can exactely confirm your statement. Whenever you have the time to change that in TOAD, it would make me happy
