Description. This method is used to determine whether the column is part of the table's primary key.
Important
The NDB API handles column names in case-sensitive fashion; “myColumn” and “Mycolumn” are not considered to refer to the same column. It is recommended that you minimize the possibility of errors from using the wrong lettercase for column names by naming all columns consistently using only uppercase or only lowercase.

of the primary key of the table to which this column belongs,
otherwise false.
