The Edit Field tab allows you to edit the contents ot a single database field. This is useful for text field that contain large amounts of text when you want to change only a few characters.
To edit a field, fill in the fields that specify what field to edit:
Table: the name of the database table containing the data
Column: the name of the column in that table you want to change
Where: an SQL query expression that selects a single row from the specified table
After filling in the above fields, press the Edit Field button. If the WHERE clause does not select exactly one row, an error dialog will be presented. If exactly one row is selected, a dialog will appear with the contents of the specified field of that row. After changing the contents as desired, press the OK to save your changes to the database.
