Description. This method is used to make a column part of the table's primary key, or to remove it from the primary key.
Important
Changes made to columns using this method are not visible to MySQL.
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.
