1.23. SQLite Order By

发布时间 :2025-10-25 12:31:15 UTC      

SQLite’s ORDER BY Clause is used to sort data in ascending or descending order based on one or more columns.

1.23.1. Grammar

ORDER BY The basic syntax of the clause is as follows:

SELECT column-list
FROM table_name
[WHERE condition]
[ORDER BY column1, column2, .. columnN] [ASC | DESC];

You can find it in the ORDER BY Multiple columns are used in the clause. Make sure that the sort you use is listed in the list.

1.23.2. Example

Hypothetical COMPANY The table has the following records:

ID          NAME        AGE         ADDRESS     SALARY
----------  ----------  ----------  ----------  ----------
1           Paul        32          California  20000.0
2           Allen       25          Texas       15000.0
3           Teddy       23          Norway      20000.0
4           Mark        25          Rich-Mond   65000.0
5           David       27          Texas       85000.0
6           Kim         22          South-Hall  45000.0
7           James       24          Houston     10000.0

Here is an example that presses the result SALARY Sort in ascending order:

sqlite> SELECT * FROM COMPANY ORDER BY SALARY ASC;

This will produce the following results:

ID          NAME        AGE         ADDRESS     SALARY
----------  ----------  ----------  ----------  ----------
7           James       24          Houston     10000.0
2           Allen       25          Texas       15000.0
1           Paul        32          California  20000.0
3           Teddy       23          Norway      20000.0
6           Kim         22          South-Hall  45000.0
4           Mark        25          Rich-Mond   65000.0
5           David       27          Texas       85000.0

Here is an example that presses the result NAME And SALARY Sort in ascending order:

sqlite> SELECT * FROM COMPANY ORDER BY NAME, SALARY ASC;

This will produce the following results:

ID          NAME        AGE         ADDRESS     SALARY
----------  ----------  ----------  ----------  ----------
2           Allen       25          Texas       15000.0
5           David       27          Texas       85000.0
7           James       24          Houston     10000.0
6           Kim         22          South-Hall  45000.0
4           Mark        25          Rich-Mond   65000.0
1           Paul        32          California  20000.0
3           Teddy       23          Norway      20000.0

Here is an example that presses the result NAME Sort in descending order:

sqlite> SELECT * FROM COMPANY ORDER BY NAME DESC;

This will produce the following results:

ID          NAME        AGE         ADDRESS     SALARY
----------  ----------  ----------  ----------  ----------
3           Teddy       23          Norway      20000.0
1           Paul        32          California  20000.0
4           Mark        25          Rich-Mond   65000.0
6           Kim         22          South-Hall  45000.0
7           James       24          Houston     10000.0

2           Allen       25          Texas       15000.0

Principles, Technologies, and Methods of Geographic Information Systems  102

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
