Syntax Generated by Heidi generates Syntax Error

This is the syntax generated:

CREATE TABLE "test" (
"uniqueid" INT NOT NULL,
PRIMARY KEY ("uniqueid"),
UNIQUE INDEX "uniqueid" ("uniqueid")
)
;

I am newbie and probably missing something quite important. However I understood that HEIDI should work not only with mySQL where the same syntax has worked without any problem.

Thanks a lot. Help Please.
