Use Shift Del   More info  Shift Del combination key set a field to null when you filled a field by a value and you changed your decision and you want to make it null  It is useful and I amazed from the other answers that give strange solutions

It is clear that most people who haven t used SQL Server Enterprise Manager don t understand the question  i e  Justin Cave      I came upon this post when I wanted to know the same thing   Using SQL Server  when you are editing your data through the MS SQL Server GUI Tools  you can use a KEYBOARD SHORTCUT to insert a NULL rather than having just an EMPTY CELL  as they aren t the same thing   An empty cell can have a space in it  rather than being NULL  even if it is technically empty  The difference is when you intentionally WANT to put a NULL in a cell rather than a SPACE or to empty it and NOT using a SQL statement to do so    So  the question really is  how do I put a NULL value in the cell INSTEAD of a space to empty the cell   I think the answer is  that the way the Oracle Developer GUI works  is as Laniel indicated above    And THAT should be marked as the answer to this question   Oracle Developer seems to default to NULL when you empty a cell the way the op is describing it   Additionally  you can force Oracle Developer to change how your null cells look by changing the color of the background color to further demonstrate when a cell holds a null   Tools- Preferences- Advanced- Display Null Using Background Color  or even the VALUE it shows when it s null   Tools- Preferences- Advanced- Display Null Value As  Hope that helps in your transition

You ll have to write the SQL DML yourself explicitly  i e   UPDATE  lt table gt     SET  lt column gt    NULL    Once it has completed you ll need to commit your updates  commit    If you only want to set certain records to NULL use a WHERE clause in your UPDATE statement   As your original question is pretty vague I hope this covers what you want

If you want to use the GUI    click double-click the table and select the Data tab  Click in the column value you want to set to  null   Select the value and delete it  Hit the commit button  green check-mark button   It should now be null     More info here   How to use the SQL Worksheet in SQL Developer to Insert  Update and Delete Data
