Questions about database

Question

1. The teacher said to create a new table student in myblog. Why is it the database myblog?

2. How does the student table connect with the zhibo/3 project? How does this project know which database or data table is for him to use?

Answer 1

Through the configuration table, you can also change a database name, but if you change the name, you need to modify it in the configuration file.

Why the program recognizes this database as you mentioned is because in the configuration file, it is specified to use this database, so it can only search the tables under this database

Answer 2

Because your myblog database requires the student table, it is only valid under this table; find the connection between the two tables. For example, if the data in different fields under the two tables are the same, you can establish a connection between the two fields. .
