Inlay Hints

Inlay hints are special markers that appear in the editor and provide you with additional information about your code, like the names of the parameters. Other types of hints inform you about annotations, code authors, usages, and so on (depending on the language).

Enable or disable inlay hints

  • To disable a hint that is currently in front of you in the editor:

    Right-click the hint and select whether you want to disable the specific type of hints or all hints in this category.

    Alternatively, click the hint, press Alt+Enter and select Disable option <inlay_hint_option_name> inlay hint.

    Disable an inlay hint option in the code editor

  • To configure one or more specific groups of inlay hints:

    Open the Settings dialog (Ctrl+Alt+S) , go to Editor | Inlay Hints, and use the checkboxes next to the hints to hide or show the corresponding category of inlay hints.

In inlay hints settings, you can configure what types of information you want to get in hints.

Change inlay hints appearance

  1. In the Settings dialog (Ctrl+Alt+S) , go to Editor | Color Scheme | Language Defaults, then select Inline hints.

  2. Select the inlay hint type and state, and configure the font color and effects as required.

    db_in_select_expressions

  • For * references: show names of columns for asterisk (*) references in SELECT statements that have context that sets column names. For example, SELECT statements inside CREATE VIEW and INSERT. Works only in query files, not as a language injection.

    For asterisk references

  • For set operations (UNION, INTERSECT, EXCEPT): show names of columns in SELECT statements when they are used in set operations like UNION, INTERSECT, and EXCEPT. Works only in query files, not as a language injection.

    For set operations

JOIN cardinality

Display the numerical relationship between rows of one table and rows in the other. Common cardinalities include one-to-one (1<->1), one-to-many (1<->1..n), many-to-many(1..n<->1..n), and optional (0..n). The optional cardinality appears when the referring field is nullable.

You can configure inlay hints for the following types of JOIN:

  • INNER JOIN

  • LEFT JOIN

  • RIGHT JOIN

  • FULL JOIN
