+#시퀀스 생성 관련
+1. 테이블의 PK를 INT UNSIGNED AUTO_INCREMENT 로 지정 예) LOGIN_HST_SQ INT UNSIGNED AUTO_INCREMENT COMMENT '로그인이력일련번호'
+2. mybatis XML의 insert문에 keyProperty 속성 추가. 예) keyProperty="loginHstSq"
+3. JAVA 소스에서는 Domain의 get Method를 이용해 추출.
+	예)
+		void createLoginHistory(GaaLoginHst loginHst);
+		loginHst.getLoginHstSq();
