        Gets the row specified by the primary key value.
        Parameters:
        primaryKeyValue - The primary key value of the DataRow to find.
        Returns:
        A DataRow that contains the primary key value specified; otherwise a null value if the primary key value does not exist in the DataRowCollection.

      • find

        public DataRow find(java.lang.Object[] keys)
        Gets the row that contains the specified primary key values.
        Parameters:
