请问下各个大佬，这个问题该怎么解决？
ALTER TABLE "SPARK"."AUTH_ACCOUNT" ADD CONSTRAINT "CONS134221202" UNIQUE("ID");

AUTH_ACCOUNT的结构如下：
CREATE TABLE "SPARK"."AUTH_ACCOUNT"
(
"ID" NUMBER(5,0) NOT NULL,
"ACCOUNT_NAME" CHAR(64) NOT NULL,
"ACCOUNT_COMMENTS" CHAR(64) NOT NULL,
"ROLE_ID" NUMBER(5,0) NOT NULL,
"PASSWORD" CHAR(64) NOT NULL,
CLUSTER PRIMARY KEY("ID")) STORAGE(ON "SPARK", CLUSTERBTR) ;
