在SQL中替换多个字符？

Question

我如何显示* 具有以下条件：

1. 学号必须不包含以下字符串：231
2. 姓氏必须以字母S
开头
3. 课程编号不得为DEV1或DEV2

Answer 1

你可以试试这个：

 Select * From [TableName] 
 Where Studend_Number not like '%231%' and 
       Student_Surname like '%S' and 
       Course_Number not in ('DEV1','DEV2')

Answer 2

Use 3 conditions in WHERE Clauses :

SELECT *
FROM Your_table 
WHERE Studentnumber NOT LIKE '%231%' AND surname LIKE 'S%' AND coursenumber 
NOT IN ('DEV1', 'DEV2')

Answer 3

SELECT * 
FROM tablename 
WHERE student_number <> 231 
   AND surname LIKE 's%' 
   AND coursenumber NOT IN ('DEV1','DEV2')
