 Trong bài viết này, chúng tôi sẽ tham gia hai bảng bằng PHP và hiển thị chúng trên trang web. & NBSP; Giới thiệu : PHP là ngôn ngữ kịch bản phía máy chủ, được sử dụng để kết nối với cơ sở dữ liệu. Sử dụng điều này, chúng ta có thể lấy dữ liệu từ cơ sở dữ liệu bằng cách sử dụng các tập lệnh PHP. Ngôn ngữ cơ sở dữ liệu có thể được sử dụng để giao tiếp với PHP là MySQL. MySQL là ngôn ngữ truy vấn cơ sở dữ liệu được sử dụng để quản lý cơ sở dữ liệu. Yêu cầu: Máy chủ XAMPP - Máy chủ XAMPP được sử dụng để lưu trữ cơ sở dữ liệu của chúng tôi tại địa phương. & nbsp; chúng tôi sẽ truy cập dữ liệu từ máy chủ XAMPP bằng PHP. Trong bài viết này, chúng tôi đang lấy cơ sở dữ liệu chi tiết sinh viên có chứa hai bảng. Họ là Student_Address và Student_marks. Cấu trúc của bảng: table1=student_address table2=student_marks. Chúng tôi sẽ thực hiện tham gia bên trong, tham gia bên trái, tham gia bên phải trên hai bảng này. 1. Tham gia bên trong: Tham gia bên trong là một từ khóa chọn các bản ghi có các giá trị phù hợp trong cả hai bảng. Cú pháp: SELECT column 1,column 2,...column n FROM table1 INNER JOIN table2 ON table1.column_name = table2.column_name; Thí dụ : Hãy để student_address chứa những chi tiết này Và bảng student_marks bao gồm Bằng cách sử dụng SID, chúng ta có thể tham gia hai bảng này bằng cách sử dụng tham gia bên trong, vì, SID là phổ biến trong hai bảng.
SELECT * from student_address INNER JOIN student_marks on student_address.sid=student_marks.sid; Kết quả : STUDENT-ID : 1 ----- NAME : sravan kumar ----- ADDRESS : kakumanu STUDENT-ID : 2 ----- NAME : bobby ----- ADDRESS : kakumanu STUDENT-ID : 3 ----- NAME : ojaswi ----- ADDRESS : hyderabad STUDENT-ID : 4 ----- NAME : rohith ----- ADDRESS : hyderabad
SELECT * from student_marks INNER JOIN student_address on student_address.sid=student_marks.sid Kết quả : STUDENT-ID : 1 ----- SUBJECT 1 : 98 ----- SUBJECT 2 : 99 STUDENT-ID : 2 ----- SUBJECT 1 : 78 ----- SUBJECT 2 : 89 STUDENT-ID : 3 ----- SUBJECT 1 : 78 ----- SUBJECT 2 : 98 STUDENT-ID : 4 ----- SUBJECT 1 : 89 ----- SUBJECT 2 : 98 Truy vấn để hiển thị chi tiết Student_marks dựa trên tham gia bên trong. 2. Tham gia trái: Cú pháp: SELECT column1,column2,...columnn FROM table1 LEFT JOIN table2 ON table1.column_name = table2.column_name;
SELECT * from student_address LEFT JOIN student_marks on student_address.sid=student_marks.sid Kết quả : STUDENT-ID : 1 ----- NAME : sravan kumar ----- ADDRESS : kakumanu STUDENT-ID : 2 ----- NAME : bobby ----- ADDRESS : kakumanu STUDENT-ID : 3 ----- NAME : ojaswi ----- ADDRESS : hyderabad STUDENT-ID : 4 ----- NAME : rohith ----- ADDRESS : hyderabad STUDENT-ID : ----- NAME : gnanesh ----- ADDRESS : hyderabad
SELECT * from student_marks LEFT JOIN student_address on student_address.sid=student_marks.sid Kết quả : STUDENT-ID : 1 ----- SUBJECT 1 : 98 ----- SUBJECT 2 : 99 STUDENT-ID : 2 ----- SUBJECT 1 : 78 ----- SUBJECT 2 : 89 STUDENT-ID : 3 ----- SUBJECT 1 : 78 ----- SUBJECT 2 : 98 STUDENT-ID : 4 ----- SUBJECT 1 : 89 ----- SUBJECT 2 : 98 STUDENT-ID : ----- SUBJECT 1 : 89 ----- SUBJECT 2 : 79 Truy vấn để hiển thị chi tiết Student_marks dựa trên tham gia bên trong. 2. Tham gia trái: Cú pháp: SELECT * from student_address INNER JOIN student_marks on student_address.sid=student_marks.sid;0
SELECT * from student_address INNER JOIN student_marks on student_address.sid=student_marks.sid;1 Kết quả : SELECT * from student_address INNER JOIN student_marks on student_address.sid=student_marks.sid;2
SELECT * from student_address INNER JOIN student_marks on student_address.sid=student_marks.sid;3 Kết quả : SELECT * from student_address INNER JOIN student_marks on student_address.sid=student_marks.sid;4 Truy vấn để hiển thị chi tiết Student_marks dựa trên tham gia bên trong.
Steps:
Truy vấn để hiển thị tất cả bảng student_address dựa trên ID sinh viên bằng cách sử dụng & nbsp; tham gia đúng Truy vấn để hiển thị tất cả các sinh viên_mark & nbsp; bảng dựa trên id sinh viên
Tạo cơ sở dữ liệu có tên cơ sở dữ liệu và tạo bảng (student_address và student_marks)STUDENT-ID : 1 ----- NAME : sravan kumar ----- ADDRESS : kakumanu STUDENT-ID : 2 ----- NAME : bobby ----- ADDRESS : kakumanu STUDENT-ID : 3 ----- NAME : ojaswi ----- ADDRESS : hyderabad STUDENT-ID : 4 ----- NAME : rohith ----- ADDRESS : hyderabad1 Chèn bản ghi vào hai bảng bằng PHP Viết SQL & NBSP; truy vấn để thực hiện tất cả các lần tham gia bằng PHP Quan sát kết quả. Bắt đầu máy chủ XAMPP Nhập trực tuyến localhost/phpmyadmin, trong trình duyệt của bạn và tạo cơ sở dữ liệu có tên là cơ sở dữ liệu, sau đó tạo hai bảng có tên student_address và student_marks
