Selecting columns for analyzing
This step of the wizard allows you to select columns of the table being edited for analyzing them.
Max count of distinct values
Use this field to set the maximum number of distinct values per column that will be analyzed. This value is used to check whether the optimal data type should be of type ENUM; if there are more than defined value of distinct values, then ENUM is not a suggested type.
To select a field, you need to move it from the Available Columns list to the Included Columns list. Use the
buttons or drag-and-drop operations to move the fields from one list to another.
