You can recognize Jinja based on the delimiters the language uses, which we refer to as "curlies":
- **Expressions `{{ ... }}`**: Expressions are used when you want to output a string. You can use expressions to reference [variables](/reference/dbt-jinja-functions/var) and call [macros](/docs/build/jinja-macros#macros).
- **Statements `{% ... %}`**: Statements are used for control flow, for example, to set up `for` loops and `if` statements, or to define macros.
- **Comments `{# ... #}`**: Jinja comments are used to prevent the text within the comment from compiling.
- **Statements `{% ... %}`**: Statements don't output a string. They are used for control flow, for example, to set up `for` loops and `if` statements, to [set](https://jinja.palletsprojects.com/en/3.1.x/templates/#assignments) or [modify](https://jinja.palletsprojects.com/en/3.1.x/templates/#expression-statement) variables, or to define macros.
- **Comments `{# ... #}`**: Jinja comments are used to prevent the text within the comment from executing or outputing a string.

When used in a dbt model, your Jinja needs to compile to a valid query. To check what SQL your Jinja compiles to:
* **Using dbt Cloud:** Click the compile button to see the compiled SQL in the Compiled SQL pane
