 The query history **Format** setting controls how the extension lists queries in the query history. By default, each item has a label with the following format::

+Configuring settings for adding databases
+------------------------------------------------
+
+To automatically add database source folders to your workspace, you can enable the **Adding Databases > Add Database Source to Workspace** setting.
+
+This setting is disabled by default. You may want to enable the setting if you regularly browse the source code of databases, for example to view the abstract syntax tree of the code. For more information, see ":ref:`Exploring the structure of your source code <exploring-the-structure-of-your-source-code>`."
+
+.. pull-quote:: Note
+
+   If you are in a single-folder workspace, adding database source folders will cause the workspace to reload as a multi-root workspace. This may cause query history and database lists to be reset.
+
+   Before enabling this setting, we recommend that you save your workspace as a multi-root workspace. For more information, see "`Multi-root Workspaces <https://code.visualstudio.com/docs/editor/multi-root-workspaces>`__" in the Visual Studio Code help.

    .. pull-quote:: Note
 
       If you don't have an appropriate ``printAST.ql`` query in your workspace, the **CodeQL: View AST** command won't work. To fix this, you can update your copy of the `CodeQL <https://github.com/github/codeql>`__ repository from ``main``. If you do this, you may need to upgrade your databases. Also, query caches may be discarded and your next query runs could be slower.
