5.10 동일(중복) 자료 삭제 방법[편집]

  1. ROW_NUMBER() 이용
DELETE FROM 테이블명
	WHERE ROWID IN (
		SELECT ROWID 
		  FROM (
		    	SELECT * 
		    	  FROM (
		    	    	SELECT ROW_NUMBER() OVER(PARTITION BY 컬럼명 ORDER BY 컬럼명) AS num
		    		      FROM 테이블명
		    	       )
		 WHERE num > 1 --  num의 값이 1초과인 데이터들만 삭제
	)
);
  1. MIN(ROWID) 보다 큰건은 삭제(신규 추가된건 삭제)
DELETE FROM 테이블명 A
 WHERE ROWID > (SELECT MIN(ROWID) FROM 테이블명 B
                 WHERE A.컬럼 = B.컬럼
               );
  1. MAX(ROWID) 보다 작은건 삭제 (처음 추가된건 제)
DELETE FROM 테이블명 A
 WHERE ROWID < (SELECT MAX(ROWID) FROM 테이블명 B
                 WHERE A.컬럼 = B.컬럼);
