Change the column order | In the Column name grid, remove the columns from the primary key. Then add the columns back in the order you want. To remove a column from the key, simply remove the column name from the Column name list. |
Rename the primary key | Type a new name in the Index name box. Make sure that your new name does not duplicate a name in the Selected index list. |
Set the clustered option | Select the Create as CLUSTERED check box. Only one clustered index can exist per table. If this option is not available for your index, you must first clear this setting on the existing clustered index. |
Define a fill factor | Type an integer from 0 to 100 in the Fill factor box. |
The primary key is updated in the database when you save your table or diagram.
