* Make export table locks local to current connection work.
* Bugfix: In non-file mode, export commands go directly to server without being parsed; thus they must not have semicolons at end of sentence. A regression here causes issue #1747558 and issue #1795486, which this commit fixes again.
(Briefly considered adding a cleanSql() which just runs result := parseSql(sql)[0], which would do the same in fewer lines of code, albeit with the small overhead of having the semicolon both added and afterwards removed again..)
(Views need to be exported last for an import to work properly, which is a better solution - should do that at some point. Other stuff needs to be exported too, stored procedures etc). Fixes issue #1779068.
Additionally/Sideeffects:
- Fix vstFreeNode to delete the item from the array, not only free the item itself
- Change/Rename GetSelectedNodesFromVT to GetVTCaptions and give it the ability to return all captions, not only the selected. This function is very useful now and saves writing much redundant code.
A table with 500 columns needed 3 seconds to display in the TSortListView, now that takes less than a half second.
Additionally/Side effects:
- TVTreeData structure moved to helpers.pas to be able to use it in new function GetSelectedNodesFromVT.
- ListTablesEditing dropped. We don't need to disable any shortcut there because there is none set.
- Avoid potential AVs when accessing not created items in TVTreeData.Captions
