  2. Select the Can contain nulls check box if the data in the column can include null values. This action de-selects the Values must be unique check box if it is selected.
  3. Select the Values must be unique check box if the data in the column must be unique values. This action deselects Can contain nulls.
  4. Select the Distribute by Hash check box if you want to specify a distribution key column. Using DISTRIBUTE BY HASH with a distribution key is mandatory for fact tables and optional for dimension tables. You must select at least one column in the table to distribute by hash.
  5. Click OK.
