How to query views in mysql data table

This article mainly introduces how to query the views in the mysql data table.

I believe that if you have read the previous articles related to mysql views, you already have a certain understanding of the basic concepts of views. A view is a virtual table whose contents are defined by queries. Like the MySQL data base table where the data actually exists, the view functions like a filter.

If you still have friends who are not clear about the basic knowledge of views, you can refer to the following article.

【How to create a view in mysql? 】

The previous article has already introduced how to create a mysql view. Now I will continue to use simple examples to introduce to you how to query the mysql view.

1. Query a single table view

The syntax is as follows:

select * from + 单表视图名

The syntax example of querying a single table view is as follows:

select * from my_v1;

Here we query the information of the my_v1 view, that is, query the fields in the view.

2. Query views associated with multiple tables (associating two or more tables)

The syntax is as follows:

select * from + 多表视图名

Query multiple tables The view syntax example is as follows:

select * from my_v2;

Here we query the information of the multi-table view my_v2 (a view associated with two tables), that is, query the field information in the view.

Then we can find that the SQL statements for single-table query and multi-table query are actually the same. Just pay attention to the difference between the specified view name to be queried.

Some friends may have discovered that there are garbled characters in the command line after our query view. Regarding the problem of garbled characters, we will continue to introduce and provide solutions to the garbled characters in later articles. Friends in need can continue to pay attention to the PHP Chinese website.
