Subject Re: SQL Autocompletion - Quoter Refactoring breaks quoter check
Date Sun, 20 Jun 2021 16:10:44 GMT

Adding currently identified reviewers to "To"

I realize everyone has other priorities and that the comments/discussions
on the PR may be a little chaotic and confusing so in summary, I have:
(1) Resolved issues adding logic to account for cases when connection is
not available and allow sql autocomplete to work even without an active
(2) This no longer shows the dialog asking for connection which prevented
autocompletion previously, but still shows when attempting to "execute" a
query where a connection is really needed (similar to how other sql editor
type applications may do things [i.e. wait until such time as absolutely
(3) I removed any unnecessary changes (i.e. hints - created ticket
Add SQL Hints to address this),
(4) I have squashed [to the best of my abilities] and reduced the changed
files to only applicable 3 files in the Sql Editor project, and
(5) I have adjusted the quoter logic to no longer return an empty string
and have a minimum form of quoter/unquoter which still works in the unit
tests for the SQL projects
(6) I have not re-architected to introduce any kind of "Standard SQL
Quoter" class at this time as I believe this is likely a larger effort
which I propose raising a new ticket to create a Standard SQL Quoter class
and retrofit the code as part of that work.

*Assume this would involve developing a new class for such and
handle standardized quoting of identifiers similar to what is discussed (
<> ).  *
*For this I (or whoever takes this on) would need to better understand what
the expected input/outputs are for this and what kind of tests would be
needed to confirm this does as expected beyond the existing sql tests. *

(7) There may also be another SQL improvements ticket to raise as mentioned
in this comment in the discussion

*Looking at one of the w3 resources SQL syntax page in identifier section
<> it does look more

*The w3 reference mentions after "SELECT" there can be optionally "DISTINCT
| ALL" and either a wildcard ("*") or select List (i.e. identifiers).
Unless I've missed it, I'm not sure these cases are handled. Is a new issue
for adding that worth wild?*

Does this seem acceptable?  If not, what (besides maybe raising above
tickets) is still needed?
