Again, thank you, Razzak.
I did miss the change and your tip of the day or I missed its significance but
the timing explains to me why I missed it and why I am now experiencing it.
I can now take the appropriate actions to avoid the problem for that view.
I will also see if I can rework the view to avoid the problem in the first
place.
Regards,
Alastair.

You are very welcome, Alastair!
As always, the pleasure is all mine.
There is so much being implemented that for some reason, if you missed the Tip
of the Day, or forgot to refer to What's New PDF, it can create some confusion
or sudden surprises. Thus, my reason to step-in immediately, before someone
makes their own assumptions, etc., and creates confusion for the rest of the
users on this list.
Yes, personally, I do monitor this list with interest, and always do my best to
reply, help, and/or clarify as much as I can while keeping up with my 16-18
hours a day, every day, of R:BASE development jobs and responsibilities.
For your information, the COLCHECK setting was first introduced on August 28,
2015 and then officially released on September 24, 2015 (Versions 9.5 and 10.0).
Here is a snippet from the original Tip of the Day, posted on August 28, 2015.
Please feel free to reach out to me if you have further questions.
Hope that helps!
Very Best R:egards,
Razzak

Tip of the Day: About the New COLCHECK Setting
Product.: R:BASE eXtreme 9.5 (32/64) and R:BASE X (Version 10)
Build...: 9.5.5.20924, 10.0.1.10924 or higher
Section.: Settings
Keywords: COLCHECK, CREATE VIEW, CREATE TEMPORARY VIEW, AS alias
Did you know that the upcoming update of R:BASE eXtreme 9.5 (32/64) and the
official release of R:BASE X (Version 10), to be released on September 24,
2015, include a new COLCHECK setting?
The additional COLCHECK setting has been introduced to manage common column
names and corresponding data types when used as ALIAS names while defining a
new VIEW or modifying an existing VIEW.
COLCHECK specifies if columns will be checked for consistency when making
views. When COLCHECK is ON (the default), view alias/column names will be
checked for consistency to other occurrences of those names in the database,
when the view is created.
Syntax:
SET COLCHECK ON/OFF
Similar checking is already in place when creating or modifying tables, and
when attaching tables to a database, where R:BASE requires an alias that does
not cause name/data type conflicts.
If an application requires COLCHECK be off to define a view, the proper results
should not be expected once COLCHECK is switched back to ON when using the
view. If a view needs to be created with COLCHECK OFF, it also needs to be used
with COLCHECK OFF.
An impact may occur for a view that has already been defined, because when
COLCHECK is ON, the values generated for the view will follow the data type of
the alias. If an error occurs, the view definition should be reviewed.

Thank you very much, Razzak, setting ColCheck off did the trick.
I notice that if I turn ColCheck back on I immediately get the error message
again as soon as I try to use the view.
I have looked at the names in the view almost endlessly today to try and see
where the error was so I am puzzled as to where R:Base finds a difference.
I think I would rather correct that than run with ColCheck set off all the
time. Obviously I can change the setting in a command file before and after use
but what has raised this problem is the error message is received whenever I
reconstruct the database from unloads. (But not with Reload.)
This may be a complete misinterpretation but I also have a suspicion that this
particular error has been causing problems with my user privileges. Is that
possible? If so, I may have to run with ColCheck set to off all the time. With
that in mind when was ColCheck introduced and/or was it changed with the
upgrade to v10?
Again thanks,
Regards,
Alastair.

Alastair,
A few questions ...
01. What is the COLCHECK setting?
SHOW COLCHECK
02. What results do you get when turning OFF the COLCHECK setting.
SET COLCHECK OFF
FYI, COLCHECK ON setting checks the consistency for column names and data types
when making views.
Hope that provides you with some blue's clues ...
Very Best R:egards,
Razzak.

I know it's Friday but can anybody see what's wrong with this view (an image so
that hopefully the email system doesn't mangle my layout):
If it hasn't, there should be 6 columns so that I could see the columns and
data types (first 5 rows remmed out) more easily.
I am not sure that I am defining the time entries correctly - I've tried with
as well as without quotes.
I am pretty sure I have the data types right - despite the error message.
I am not sure that I have the group by right. I only really need to group by:
T21.Concert_Date, T22.Full_Name, T23.Full_Name (date, venue name & artist name).
