Starting with JetBrains Rider 2022.1, you can change database-specific parameters of a column. The IDE generates fields for the Modify dialog automatically according to the properties received during the introspection. For example, by using this dialog in PostgreSQL, you can add and edit column check constraints.

1. In the Database tool window, right-click a column and select Modify Column.

2. In the Modify dialog, specify object settings that you need.

   note

   Column settings depend on the database vendor. For example, the Auto Increment checkbox is only available for SQLite, MySQL, and other vendors that allow it for a primary key column of an integer data type.

3. Click OK to save your changes.

• To reorder columns, drag the corresponding cells in the header row.

• To hide a column, right-click the corresponding header cell and select Hide column.

  Alternatively, you can right-click any of the cells in the header row and select Show Column List Alt0\. In the column list popup window, select a column name and press Space. You can hide all columns. To search through the column list, start typing a column name in the Show Column List window.

  

1. Right-click any of the cells in the header row and select Show Column List. Alternatively, press Alt0\.

2. Select the hidden column (a strikethrough column name) and press Space.

   

• Click the settings icon () and select Reset View. As a result, the data becomes unsorted, the columns appear in the order they were defined initially, and all the columns are shown.

  

• You can assign HTML, CSS, XML, RegExp, or any other formal language for the whole column. So, when you have a piece of code inside the cell that belongs to the column, you can use code generation, code completion, and other IDE features.

  To inject a language for the whole column, right-click the corresponding header cell, and select Set Highlighting Language. In the list of supported languages, select the language that you want to inject.

  

• Place the caret between two columns, so it changes to the resize mode. Drag it to the preferred position.
