I'm using the MySQL Query Browser (part of the MySQL GUI Tools) and need to change a field to NULL, but I can't figure out how to do it - if I delete the value it tries to update it to ''. Typing "NULL" makes it try to update to 'NULL' (a string).
I know I could just write a query to do it, but that defeats the entire purpose of the tool, no?

MySQL SET NULL Values in UPDATE StatementBy using the assignment operator (“=”), you can set any value of a column to NULL by using the Update Statement.
You can insert NULL value into an int column with a condition i.e. the column must not have NOT NULL constraints. The syntax is as follows. INSERT INTO yourTableName(yourColumnName) values(NULL); To understand the above syntax, let us first create a table.
You can right-click on a cell and choose "Clear Field Content" in the popup menu. It will set the cell value to NULL.
Use IFNULL or COALESCE() function in order to convert MySQL NULL to 0. Insert some records in the table using insert command. Display all records from the table using select statement.
In MySQL Query Browser, right click on the cell and select 'Clear field content' while the focus is in another cell.
In MySQL Workbench, right click on the cell and select 'Set Field to NULL'.
