Productivity tips

Set default values for a cell

When a new row is created and no values are specified for some of the cells, those cells are filled with their respective default Ctrl+Alt+D or NULL (Ctrl+Alt+N) values.

When you set default values for a cell, you can use corresponding actions from the context menu (Set DEFAULT and Set NULL).

  1. In the Database tool window (View | Tool Windows | Database), expand a data source tree.

  2. Right-click the table and select Modify Table Ctrl+F6.

  3. On the Columns tab, double-click the column that you want to edit.

  4. In the Default field, specify the default value of the cell in the column. To allow NULL values, clear the Not null checkbox.

Edit multiple cell values simultaneously

  1. Select a range of cells that you want to edit.

  2. Start typing a new value. The changes are applied to all the selected cells.

  3. To confirm the value, press Enter. To cancel editing, press Escape.

Saving a LOB into a file

You can save a binary large object (BLOB or LOB) from a cell into a file.

  1. Right-click the cell that contains the LOB and select Save LOB.

  2. In the save dialog, specify the name and location of the file and click OK.

Copy and paste cells between tables

  • You can copy Ctrl+C and paste Ctrl+V selected cells and ranges of cells - within the same table or from one table to another one. When pasting, PyCharm converts data types automatically if and as necessary.
