Create primary Key

[Olivier Goossens Bara]

Hello I use ddldump to extract a table definition, then I use the create syntax to create a new table in another Database but the primary key definition gives an error message, what is wrong ?
Why the syntax extracted from an existing table does not work ?
If I remove the the two instruction to create primary field and key, it works.

Thanks for any help

CREATE TABLE IF NOT EXISTS are (
DsetId bigint(10) default NULL,
SecId bigint(10) default NULL,
AreItmId bigint(10) default NULL,
LayerId int(2) default NULL,
FeatClass int(4) default NULL,
SplitInd char(1) default NULL,
NrFaces bigint(10) default NULL,
NrAttSets int(10) default NULL,
DummyFeat char(1) default NULL,
primary int(10) NOT NULL auto_increment,
PRIMARY KEY (primary),
KEY Area (AreItmId),
KEY Feat (FeatClass)
) TYPE=MyISAM;
