--- title: Questions overview --- # Questions overview Questions are queries plus their visualization. You can ask questions using Metabase's graphical query builder, or create a native/SQL query. ## Query builder ### [Asking questions](./query-builder/introduction.md) An introduction to Metabase's graphical query builder. ### [Custom expressions](./query-builder/expressions.md) Custom expressions, like spreadsheet formulas, are tools you can use in the graphical query builder to ask more complicated questions. ### [List of expressions](./query-builder/expressions.md) A list of the aggregations and functions available in the graphical query builder. ### [Joining data](./query-builder/join.md) You can join data to combine your current data with another table, or even with a saved question. ## Native query editor Also known as the SQL editor (we say native because you can also query databases that don't use SQL, like MongoDB and Google Analytics). ### [Introduction to the native query editor](./native-editor/writing-sql.md) Write native code (like SQL) to query your data source. ### [SQL templates](./native-editor/sql-parameters.md) Pass parameters into variables in your SQL templates. ### [SQL snippets](./native-editor/sql-snippets.md) Reuse and share bits of SQL. ## Sharing results There are many different ways to share the results of questions. To share the results of a dashboard, see [Dashboard subscriptions](../dashboards/subscriptions.md). ### [Sharing answers](./sharing/answers.md) Save questions, download results, and share links. ### [Visualizing results](./sharing/visualizing-results.md) Choose from a variety of visualization types. ### [Alerts](./sharing/alerts.md) Get results via email or Slack, either on a schedule, or only when something interesting happens. ### [Public sharing](./sharing/public-links.md) Create links or embeds for the good people of the internet. ### [Exporting](./sharing/exporting-results.md) The different ways you can export the results of questions and dashboards.
