The Rel Forum

Thank you. I like your suggested bypass because since I posted this problem I've been surrounding the code with begin/end for other reasons. My own bypass had been to use direct assignment: x := (extend TABLE_DEE <etc.>) union x;

This might have to be just a heads up to begin with. I can't give a specific example at this time because the examples where this bug is hitting me are too complex. Sometimes, when I give an INSERT command, with a complex expression as source and a target of existing high cardinality, the operation ...

Try this: var x base relation{z char} key{z}; insert x extend TABLE_DEE : {z := '//'}; I get ERROR: Encountered "insert" at line 1, column 1. Was expecting one of: "BEGIN" ... "TCLOSE" ... <TUPLE> ... "WITH" ... <TUPLE> ... I have used a bypass of this kind so...

Thanks for the confirmation.

I fully agree with the change. On reflection, I feel rather ashamed of exploiting what I would regard as a bug in previous versions!

Hugh

This might not be a bug, but rather a change resulting from a bug fix, but I'm asking the question under this rubric for want of a more appropriate one. In all versions up to V3.012 the following expression was legal: rel{tup{x1 1}} rename {suffix '1' as '', x as y} resulting in rel{tup{y 1}} In V3....

Yes, I did later think of using parens, but our grammar does specify WHERE <bool exp>.

Hugh

Rel allows the use of WITH in a <bool exp> but not when the <bool exp> is given as a WHERE condition.

I tested this with and .

Hugh

Actually I don't have that setting. And now I notice that the problem arises only when I use Edit, and it stays in effect when I cease editing and just use Show.
Hugh

The one on the right.

In "Rel" mode, to keep the scroll bar available I have to keep the window very wide, usually with a large amount of unused space, occupying most of my screen. This is annoying when I need to look at that window at the same time as other windows. The same problem does not arise in command m...

Every time I open a certain database that I've had for several years, I get the "Welcome" thing in Rel and no history in command line mode. I found that the system's history relvar didn't exist, so I created it, using text from another database's backup file, but that didn't help. How can ...

Here's a strange one that has only emerged with improved copy-and-paste in v3.011. I copy something from Rel 's output pane and paste it somewhere, no problem. Then, with Rel still running I go to another (non- Rel )window and use ctrl+c or edit/copy from there. When I then try to paste that somewhe...

I've installed v3.011 since I reported this bug and the related one concerning TUPLE{...}. The TUPLE bug seems to have been fixed, but not this one. Here's the example you asked for:

Now I find I can't recreate the problem either. Sorry.

Hugh

Please ignore previous post. I didn't read carefully enough.
