SQL Syntax Highlighting
Introduction
The SQL view of the query designer, which displays, and allows to edit, raw SQL statements, currently is a mere text input field. It would be helpful especially to the unexperienced user to support the users by various means and make it more convinient.
The cws for ongoing implementation will be CWS sqlsyntaxhighlighting
Detailed Information
Feature Description
Three new features will be implemented:
- Syntax highlighting will be added: SQL keywords, literals and the like will be notable Issue 67961
- The SQL view will respect the settings from Tools-Options-Fonts, where you can set a font name as well as a font size Issue 91687
- To support users writing complex queries including bracket terms, matching characters will be shortly highlighted when pressing },)," or '
Technical details
Instead of duplicating neccessary code for EditView/EditEngine/TextWindow again, a new control MultiLineEditSyntaxHighlight will be created, which will be derived from a MultiLineEdit, which actually already does all the EditView/EditEngine stuff already as a nice usable control. So this new control will be the same as a MultiLineEdit, but will be able to do the new stuff as well. As the current Base SQL view is using a MultiLineEdit already, it will be extremly easy to use the new control.

Future work
end user
To further improve the usability, it would be nice to have the possibility to
- insert various SQL and user code snippets
- code completion including SQL keywords, table and field names
code base
If the BASIC IDE as well as HTML source view only need regular MultiLineEdit functionality, the new code could be used for these two cases as well. This would get rid of a lot of code and would make it more maintainable.
