Hibernate 프레임워크에서 HQL과 SQL의 차이점은 무엇입니까?
Apr 17, 2024 pm 02:57 PM
HQL과 SQL은 Hibernate 프레임워크에서 비교됩니다. HQL(1. 객체 지향 구문, 2. 데이터베이스 독립적 쿼리, 3. 유형 안전성), SQL은 데이터베이스를 직접 운영합니다(1. 데이터베이스 독립적 표준, 2. 복잡한 실행 파일) 쿼리 및 데이터 조작).
Go 언어는 데이터베이스의 추가, 삭제, 수정 및 쿼리 작업을 어떻게 구현합니까?
Mar 27, 2024 pm 09:39 PM
Go 언어는 효율적이고 간결하며 배우기 쉬운 프로그래밍 언어입니다. 동시 프로그래밍과 네트워크 프로그래밍의 장점 때문에 개발자들이 선호합니다. 실제 개발에서 데이터베이스 작업은 필수적인 부분입니다. 이 기사에서는 Go 언어를 사용하여 데이터베이스 추가, 삭제, 수정 및 쿼리 작업을 구현하는 방법을 소개합니다. Go 언어에서는 일반적으로 사용되는 SQL 패키지, Gorm 등과 같은 타사 라이브러리를 사용하여 데이터베이스를 운영합니다. 여기서는 sql 패키지를 예로 들어 데이터베이스의 추가, 삭제, 수정 및 쿼리 작업을 구현하는 방법을 소개합니다. MySQL 데이터베이스를 사용하고 있다고 가정합니다.
PHP 코딩 방법: Goto 문에 대한 대안 거부
Mar 28, 2024 pm 09:24 PM
PHP 코딩 방법: Goto 문에 대한 대안 사용 거부 최근 몇 년간 프로그래밍 언어의 지속적인 업데이트와 반복으로 인해 프로그래머는 코딩 사양과 모범 사례에 더 많은 관심을 기울이기 시작했습니다. PHP 프로그래밍에서 goto 문은 오랫동안 제어 흐름 문으로 존재해 왔지만, 실제 응용에서는 코드의 가독성과 유지 관리성이 떨어지는 경우가 많습니다. 이 기사에서는 개발자가 goto 문 사용을 거부하고 코드 품질을 향상시키는 데 도움이 되는 몇 가지 대안을 공유합니다. 1. goto 문 사용을 거부하는 이유는 무엇입니까? 먼저 그 이유를 생각해 보자.

Apr 17, 2024 pm 12:09 PM
Hibernate 다형성 매핑은 상속된 클래스를 데이터베이스에 매핑할 수 있으며 다음 매핑 유형을 제공합니다. Join-subclass: 상위 클래스의 모든 열을 포함하여 하위 클래스에 대한 별도의 테이블을 생성합니다. 클래스별 테이블: 하위 클래스별 열만 포함하는 하위 클래스에 대한 별도의 테이블을 만듭니다. Union-subclass: Joined-subclass와 유사하지만 상위 클래스 테이블이 모든 하위 클래스 열을 통합합니다.
iOS 18에는 손실되거나 손상된 사진을 검색할 수 있는 새로운 '복구된' 앨범 기능이 추가되었습니다.
Jul 18, 2024 am 05:48 AM
Apple의 최신 iOS18, iPadOS18 및 macOS Sequoia 시스템 릴리스에는 사진 애플리케이션에 중요한 기능이 추가되었습니다. 이 기능은 사용자가 다양한 이유로 손실되거나 손상된 사진과 비디오를 쉽게 복구할 수 있도록 설계되었습니다. 새로운 기능에는 사진 앱의 도구 섹션에 '복구됨'이라는 앨범이 도입되었습니다. 이 앨범은 사용자가 기기에 사진 라이브러리에 포함되지 않은 사진이나 비디오를 가지고 있을 때 자동으로 나타납니다. "복구된" 앨범의 출현은 데이터베이스 손상으로 인해 손실된 사진과 비디오, 사진 라이브러리에 올바르게 저장되지 않은 카메라 응용 프로그램 또는 사진 라이브러리를 관리하는 타사 응용 프로그램에 대한 솔루션을 제공합니다. 사용자는 몇 가지 간단한 단계만 거치면 됩니다.
HTML이 데이터베이스를 읽는 방법에 대한 심층 분석
Apr 09, 2024 pm 12:36 PM
HTML은 데이터베이스를 직접 읽을 수 없지만 JavaScript 및 AJAX를 통해 읽을 수 있습니다. 단계에는 데이터베이스 연결 설정, 쿼리 보내기, 응답 처리 및 페이지 업데이트가 포함됩니다. 이 기사에서는 JavaScript, AJAX 및 PHP를 사용하여 MySQL 데이터베이스에서 데이터를 읽는 실제 예제를 제공하고 쿼리 결과를 HTML 페이지에 동적으로 표시하는 방법을 보여줍니다. 이 예제에서는 XMLHttpRequest를 사용하여 데이터베이스 연결을 설정하고 쿼리를 보내고 응답을 처리함으로써 페이지 요소에 데이터를 채우고 데이터베이스를 읽는 HTML 기능을 실현합니다.
PHP를 사용하여 데이터베이스에서 중국어 왜곡 문자를 처리하기 위한 팁과 사례
Mar 27, 2024 pm 05:21 PM
PHP는 웹사이트 개발에 널리 사용되는 백엔드 프로그래밍 언어로, 강력한 데이터베이스 운영 기능을 갖추고 있으며 MySQL과 같은 데이터베이스와 상호 작용하는 데 자주 사용됩니다. 그러나 한자 인코딩의 복잡성으로 인해 데이터베이스에서 잘못된 한자를 처리할 때 문제가 자주 발생합니다. 이 기사에서는 잘못된 문자의 일반적인 원인, 솔루션 및 특정 코드 예제를 포함하여 데이터베이스에서 중국어 잘못된 문자를 처리하기 위한 PHP의 기술과 사례를 소개합니다. 문자가 왜곡되는 일반적인 이유는 잘못된 데이터베이스 문자 집합 설정 때문입니다. 데이터베이스를 생성할 때 utf8 또는 u와 같은 올바른 문자 집합을 선택해야 합니다.
