Some time ago you mentioned that CAST_AS_CHARACTER(OPERATOR) and CAST_AS_OPERATOR(CHARACTER)
exist internally and were going to be exposed to users in a future update. These operators would be a most
welcomed addition to Rel.
As always, thanks for Rel

Re: Rev query problems
Former query "QUERY10 IN Rev FOR SPLITTING STRINGS." that had problems is
now query "12.31.17 NEW QUERY10 FOR SPLITTING". After making several changes
the new query loads and executes with no problems. All is well in rev!

The curious case of OPERATOR ABS(INTEGER).
I've been meaning to bring this to your attention for some time so here it is. There is an easy workaround but if you are unaware of this problem it can cause serious grief :D Running Relv3.010 on WINDOWS 10. It would seem ABS(INTEGER) always incorrectly displays a rational but is correctly recogniz...

Re: Rev query problems
Forgot to mention using Rel v.3.010. While working on the above problem query I received the following error in the log. I have no idea if it's related to the "null" errors I'm also getting. RCP log: Status ERROR: org.eclipse.e4.ui.workbench code=0 Internal Error org.eclipse.swt.SWTError: ...

I am running a windows 10 professional system. Attached is a small txt script that will install 2 rev queries. It also contains several types and 2 operators used in the queries. The install script requires that rev already be installed in the database.The rev queries are taken from a backup script ...

Re: Key violation
Use D_INSERT:
D_INSERT foo RELATION {TUPLE {a 1, b 1}};
D_INSERT foo RELATION {TUPLE {a 2, b 1}};
ERROR: RS0232: Inserting tuple would violate uniqueness constraint of KEY {b}

I would like to see Rel have the ability to programmatically engage a user. Something similar to "prompt_Text_line" illustrated at: http://muldis.com/Muldis_D.html#hello and "io.get_line(s)" at: http://duro.sourceforge.net/docs/durodt/tut.html (see: Control statements). Scripts c...

Constraint message
I would like to see Rel offer some mechanism for allowing a user defined text message to
accompany a constraint violation. The more information conveyed in an application the better.
thanks,
steve

Re: Anticipating NatTable
Version 1.0.13 looks and sounds great! I really hope it attracts new users. Is Berkeley Java DB still being used in any way? There is no relationship between NatTable and binding relvars to external data sources. The latter is a feature of the Rel dialect of Tutorial D. When we bind to an external d...

Messaging
Hello, Is there any way to shut off messaging? In an operator I have a FOR statement that does manipulation and displays information. In the middle of the FOR and within its displays I get the "Inserted xx tuples.". In other cases I do get the message at the end. It would be nice if the &q...

Re: Anticipating NatTable
NatTable is a grid widget that integrates with the SWT widgets (see https://en.wikipedia.org/wiki/Standard_Widget_Toolkit) that I've used to build the new Rel user interface (which was formerly known as DBrowser.) Will applications written in Rel version 1.0.12 run unchanged in version 1.0.13? Will...

Hello, Can you give your users some idea of what we can expect with the introduction of NatTable.What was your motivation for it? What do you hope it will accomplish, for Rel neophyte users, for more sophisticated users. Is stored Rel data (in Berkeley Java DB) going to be accessed thru NatTable in ...
