Como evitar registros duplicados no sqlite

CREATE TABLE MAIN
   (
   NAME           TEXT    NOT NULL,
   Error_List          CHAR(50),
   Warning_List        CHAR(50),
   Advice_List         CHAR(50),
   Total          CHAR(50),
   Note           CHAR(50),
UNIQUE (NAME, Error_List, Warning_List, Advice_List, Total, Note) ON CONFLICT IGNORE
);
