public class PrimaryKey
Represents a table primary key. It can also represent a partial key,
 aligning with the key information available from
 DatabaseMetaData.
| Constructor Summary | |

| PrimaryKey()Default constructor. | |
| PrimaryKey(DBIdentifier name,
           Table table) | |
| PrimaryKey(String name,
           Table table)Deprecated. | |
| Method Summary | |
|---|---|
|  void | addColumn(Column col)Add a column to the constraint. | 
|  boolean | equalsPrimaryKey(PrimaryKey pk)Return true if the structure of this primary key matches that of the given one (same table, same columns). | 
|  boolean | isLogical()Return whether this constraint is a logical constraint only; i.e. | 
| (package private)  void | remove()Called when the constraint is removed from its table. |
