Sql server错误:INSERT语句与CHECK约束冲突

Question

INSERT语句与CHECK约束" ck_str_member_no" 冲突.冲突发生在数据库"C:\ DOCUMENTS AND SETTINGS\KARTHIKEYAN\DESKTOP\KOK\DB\INFT3009_ASS1_C3104855.MDF",表"dbo.Members",列' str_member_no'.该语句已终止.

我在visual studio 2008 Express中使用.MDF文件.我该如何解决？

我的插入程序:

---

ALTER PROCEDURE [dbo].[AddNewAGCMember] 
  -- Add the parameters for the stored procedure here
  @str_member_no varchar(6) = '', 
  @str_member_name varchar(50) = '',
  @str_member_password varchar(10) = '',    
  @str_addr_apartment_no varchar(10) = NULL,    
  @str_addr_building_name varchar(50) = NULL,   
  @str_addr_street_name varchar(50) = NULL, 
  @int_postal_code int = NULL,  
  @str_country_name varchar(50) = NULL, 
  @int_contact_no int = NULL,   
  @str_email_addr varchar(100) = '',    
  @date_registration date = ''  
AS
BEGIN
  -- SET NOCOUNT ON added to prevent extra result sets from
  -- interfering with SELECT statements.
  SET NOCOUNT ON;

  -- Insert statements for procedure here
  INSERT INTO Members 
    (str_member_no,
     str_member_name,
     str_member_password,
     str_addr_apartment_no,
     str_addr_building_name,
     str_addr_street_name,
     int_postal_code,
     str_country_name,
     int_contact_no,
     str_email_addr,
     date_registration) 
  VALUES
    (@str_member_no, 
     @str_member_name,
     @str_member_password,
     @str_addr_apartment_no,
     @str_addr_building_name,
     @str_addr_street_name,
     @int_postal_code,
     @str_country_name,
     @int_contact_no,
     @str_email_addr,
     @date_registration);
END

显然,您的插入违反了检查约束.这是数据库中执行特定检查的约束 - 数值在特定范围内,字符串最多为n个字符,或者其他任何内容.

要找出检查约束的内容,请尝试以下操作:

SELECT
name, definition 
FROM
    sys.check_constraints
WHERE
    name = 'ck_str_member_no'

这将为您提供在"定义"列中检查的表达式.

从该表达式,您应该能够确定拒绝插入的原因.解决问题并再次插入.

如果您确实无法修复数据,并且您不需要/希望检查约束,则可以删除它:

ALTER TABLE dbo.Members
   DROP CONSTRAINT ck_str_member_no
