CSCS Native Scripting vs SQL Query Logic

CSCS (Customized Scripting in C#) can now be used for native mobile development. This App contains a CSCS interpreter that you can use to play around with CSCS. There are also a few pre-set examples. You can create any CSCS scripting code in one tab, "Create", and then see the results in another tab, "Run". How to use CSCS for mobile development is described at: - https://msdn.microsoft.com/en-us/magazine/mt829272 - http://www.codemag.com/article/1711081 - https://www.smashingmagazine.com/2020/01/cscs-scripting-language-cross-platform-development/ A Syncfusion E-book describing CSCS: - https://www.syncfusion.com/resources/techportal/details/ebooks/implementing-a-custom-language Another Syncfusion E-book on how to use it for mobile development: https://www.syncfusion.com/ebooks/writing_native_mobile_apps_in_a_functional_language_succinctly The CSCS repository with the description of the language is at: https://github.com/vassilych/cscs The CSCS for mobile repository is at: https://github.com/vassilych/mobile This App itself was produced in CSCS. Here is the complete CSCS code: ========================= AutoScale(); SetBackgroundColor("cyan"); AddOrSelectTab("Create", "test.png", "test2.png"); __locComboFiles = GetLocation("ROOT", "CENTER", "ROOT", "TOP", -100, 40); AddCombobox(__locComboFiles, "__comboFiles", "center:white:clear", 350, 60); __optionsComboFiles = {"Sandbox", "Hello, World!", "Ads", "Busy Indicators", "Unit Tests"}; AddWidgetData(__comboFiles, __optionsComboFiles, "", "center"); SetFontSize(__comboFiles, 13); SetValue(__comboFiles, "text2", "Done"); SetValue(__comboFiles, "alignment", "center"); AddAction(__comboFiles, "comboFilesChanged"); __locRemoveKeyboard = GetLocation(__comboFiles, "RIGHT", __comboFiles, "CENTER", 10); AddButton(__locRemoveKeyboard, "__buttonKeyboard", "Keyboard", 150, 60); SetFontSize(__buttonKeyboard, 12); AddAction(__buttonKeyboard, "hideKeyboard"); __locScriptView = GetLocation("ROOT", "CENTER", __comboFiles, "BOTTOM", 0, 10); AddTextEditView(__locScriptView, "__textView", "", 600, 900); SetFontSize(__textView, 14); AddOrSelectTab("Run", "learn.png", "run_icon.png"); function hideKeyboard(sender, arg) { ShowHideKeyboard(__textView, false);//!IsKeyboard(__textView)); } function comboFilesChanged(sender, arg) { row = GetValue(sender); WriteConsole("Combo row=", row); text = ""; if (row == 1) { text = ReadFileAsString("sfhello.cscs"); } elif (row == 2) { text = ReadFileAsString("ads.cscs"); } elif (row == 3) { text = ReadFileAsString("busyIndicators.cscs"); } elif (row == 4) { text = ReadFileAsString("unitTests.cscs"); } SetText(__textView, text); } function tabSelected(sender, arg) { tabId = int(arg); if (tabId != 1) { return; } script = GetText(__textView); RemoveTabViews(1); try { Run(script); } catch(exc) { AlertDialog("CSCS", exc); WriteConsole(exc); } } OnTabSelected("tabSelected"); SelectTab(0);

SQL Query Logic is an independent study app for learners who want to understand how SQL queries work, not just memorize syntax. It is built for beginners, students, analysts, developers, and interview candidates who need structured practice across fundamentals, practical skills, common pitfalls, and advanced concepts. Practice through 160 focused questions, each with a clear explanation so you can learn from every answer. - FSRS spaced-repetition intervals to review at the right time - Weak-point heatmap to show topics that need attention - Daily challenge for steady practice - Mock exams for timed review - Offline practice for commutes, travel, or quiet study - No login required Use it to review SELECT logic, joins, grouping, filtering, NULL behavior, subqueries, set operations, and reasoning patterns that often cause mistakes. Independent study app for SQL Query Logic practice. Not affiliated with, endorsed by, or sponsored by any company, certification body, exam operator, or vendor.
