如何使用Mysql DB中的AngularJs从两个表中获取数据

Question

I want to fetch data from two different tables from mysql using Angular Js. My tables are shown below:

Comment

ID,User_id,Comment

User

Id,Name,Email,Password

I want to display data with angluarJs in this format:

Username : comments

Answer 1

To get all comments you want to run the following statement:

SELECT Name AS Username, Comment
FROM user, comments
WHERE user.id = comments.user_id

This is combining the two tables and matching the user_id from the comments table with the id from the users table.

Answer 2

In general, it's a bad practice to query databases directly using Angular. The recommended way of doing this is to expose the data via (RESTful) API's which in turn, perform the queries at the back-end and return the data in some format (eg, JSON) which Angular can then consume.
