推荐答案

你可以在这个列上创建一个Check Constraint，并且只允许Numbers和Alphabets 插入此列，见下文:

Your can create a Check Constraint on this column and only allow Numbersand Alphabets to be inserted in this column, see below:

ALTER TABLE Table_Name 
ADD CONSTRAINT ck_No_Special_Characters 
       CHECK (Column_Name NOT LIKE '%[^A-Z0-9]%') 

检查约束以仅允许数字

ALTER TABLE Table_Name 
ADD CONSTRAINT ck_Only_Numbers 
       CHECK (Column_Name NOT LIKE '%[^0-9]%') 

检查约束以仅允许字母

ALTER TABLE Table_Name 
ADD CONSTRAINT ck_Only_Alphabets 
       CHECK (Column_Name NOT LIKE '%[^A-Z]%')
