SQL Order By Asc

该语句用于按升序对数据进行排序。如果您没有设置 ASC 属性,SQL ORDER BY 查询默认采用升序。

让我们以供应商为例

SELECT supplier_city  
FROM suppliers  
WHERE supplier_name = 'IBM'  
ORDER BY supplier_city; 

让我们看一个包含以下记录的 CUSTOMERS 表:

ID NAME AGE ADDRESS SALARY
1 Himani gupta 21 Modinagar 22000
2 Shiva tiwari 22 Bhopal 21000
3 Ajeet bhargav 45 Meerut 65000
4 Ritesh yadav 36 Azamgarh 26000
5 Balwant singh 45 Varanasi 36000
6 Mahesh sharma 26 Mathura 22000

这是一个按 NAME 和 SALARY 升序对结果进行排序的示例。

SELECT * FROM CUSTOMERS  
ORDER BY NAME, SALARY;  

 这将产生以下结果。

ID NAME AGE ADDRESS SALARY
3 Ajeet bhargav 45 Meerut 65000
5 Balwant singh 45 Varanasi 36000
1 Himani gupta 21 Modinagar 22000
6 Mahesh sharma 26 Mathura 22000
4 Ritesh yadav 36 Azamgarh 26000
2 Shiva tiwari 22 Bhopal 21000
