PyQt5는python3.4와 sqlit3를 결합하여 작성한 작은 프로그램 원본 코드

본 프로젝트의 수요 첫 번째 단계는 excel에서 주문 데이터를 데이터베이스에 가져온 다음에 회원 이름에 따라 이 회원 이름이 진행하는 모든 거래 주문서를 조회하는 것입니다. 조회 결과는 내보내기를 지원합니다. 내보내기 형식은 excel입니다. 데이터 양이 적어서pyscopg2로postgresql를 조작하려다가 포기했습니다. 한 달에 1w개의 데이터만 가지고 있기 때문에 자체 sqlit3를 선택했습니다.
본고에서 사용한 라이브러리는xlrdxlwtsqlit3pyqt5
세 가지 종류로 나뉘는데 하나는 excel 데이터 조작 클래스입니다. 하나는 excel 데이터의 읽기와 쓰기를 포함하고 하나는db 조작 클래스입니다. 기본적인 연결 라이브러리 창설표와 조회 삽입을 포함하고 다른 하나는 인터페이스 클래스입니다. 인터페이스에 연결된 조작과 인터페이스 데이터를 가져옵니다.
원본은 다음과 같다.
