In SQL, you can use the ORDER BY clause to sort the query results in descending order. The specific syntax is: ORDER BY column name DESC, where the column name is the column to be sorted, and DESC represents descending order arrangement.
Operations for descending order in SQL
In SQL, query results can be sorted in descending order by using the ORDER BY clause. The syntax is as follows:
<code>ORDER BY 列名DESC</code>
Where,列名
is the column to be sorted, and DESC
keyword represents the descending order arrangement.
Example
For example, consider a table of students
with student grades:
<code>| id | name | score | |---|---|---| | 1 | John | 85 | | 2 | Mary | 92 | | 3 | Bob | 88 | | 4 | Alice | 95 |</code>
To sort the grades in descending order, you can use the following query:
<code>SELECT * FROM students ORDER BY score DESC;</code>
The results are as follows:
<code>| id | name | score | |---|---|---| | 4 | Alice | 95 | | 2 | Mary | 92 | | 3 | Bob | 88 | | 1 | John | 85 |</code>
As you can see, students' grades are arranged in descending order.
The above is the detailed content of How to sort SQL descending order. For more information, please follow other related articles on the PHP Chinese website!

The diversity and power of SQL make it a powerful tool for data processing. 1. The basic usage of SQL includes data query, insertion, update and deletion. 2. Advanced usage covers multi-table joins, subqueries, and window functions. 3. Common errors include syntax, logic and performance issues, which can be debugged by gradually simplifying queries and using EXPLAIN commands. 4. Performance optimization tips include using indexes, avoiding SELECT* and optimizing JOIN operations.

The core role of SQL in data analysis is to extract valuable information from the database through query statements. 1) Basic usage: Use GROUPBY and SUM functions to calculate the total order amount for each customer. 2) Advanced usage: Use CTE and subqueries to find the product with the highest sales per month. 3) Common errors: syntax errors, logic errors and performance problems. 4) Performance optimization: Use indexes, avoid SELECT* and optimize JOIN operations. Through these tips and practices, SQL can help us extract insights from our data and ensure queries are efficient and easy to maintain.

The role of SQL in database management includes data definition, operation, control, backup and recovery, performance optimization, and data integrity and consistency. 1) DDL is used to define and manage database structures; 2) DML is used to operate data; 3) DCL is used to manage access rights; 4) SQL can be used for database backup and recovery; 5) SQL plays a key role in performance optimization; 6) SQL ensures data integrity and consistency.

MySQL is a database system, and SQL is the language for operating databases. 1.MySQL stores and manages data and provides a structured environment. 2. SQL is used to query, update and delete data, and flexibly handle various query needs. They work together, optimizing performance and design are key.

The difference between SQL and MySQL is that SQL is a language used to manage and operate relational databases, while MySQL is an open source database management system that implements these operations. 1) SQL allows users to define, operate and query data, and implement it through commands such as CREATETABLE, INSERT, SELECT, etc. 2) MySQL, as an RDBMS, supports these SQL commands and provides high performance and reliability. 3) The working principle of SQL is based on relational algebra, and MySQL optimizes performance through mechanisms such as query optimizers and indexes.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
