New in v1.13

  • Preprocessor now allows resolving to unquoted strings (e.g. column names), by starting the expression inside the curly brackets with # sign e.g.: select {#columnName} from myTable
  • (Here columnName is a named range containing the name of the column to resolve. Cell references are also valid (e.g. {#A1} or {#Sheet1!A1}).)
  • C# engine:
    • Column names that have illegal C# identifier names are normalized and are now accessible as properties (not just via indexer).
    • Properties can be decorated with [System.ComponentModel.DisplayName("some name")] to control the display name of headers in results and when writing to Excel.
  • Working with cells:
    • Large speed improvements when working with cells both from C# and SQL.
    • SQLite can now run update statements on XLCells.
  • CSV file:
    • C#: The CSV function returns an object that allows updating the original data via "Commit()" method.
    • SQLite allows running an update statement on CSV tables (returned from C# TVFs).
  • New snippets - removes limitation of 200 items in autocomplete.
  • Selecting text now makes the font white (even for classes).
  • Improved startup performance.
  • Adds support for DB2.
