sql-server-2005 - 在仅提供一个输入变量的同时删除整行

Question

我有一个包含实体的表：reg_num、user_name、phone_num、designation

我想编写存储过程，只需输入 reg_num 值即可删除一行的全部数据。

create proc del @reg_num nchar(10)
as
delete reg_num, user_name, phone_num, designation from nameTable 
where reg_num = @reg_num

Answer 1

您没有为删除语句指定列：

create proc del @reg_num nchar(10)
as
delete from nameTable 
where reg_num = @reg_num

Answer 2

您只需要指定表名，不需要列出的列。

IE

create proc del @reg_num nchar(10)
as
delete from nameTable 
where reg_num = @reg_num

Answer 3

删除时，您必须遵循如下语法：

declare @regNum int
set @regnum = 1

delete from [table] where regnum = @regnum

在存储过程中，您需要这样做：

create procedure test (@regnum int) as 
begin
delete from [table] where regnum = @regnum
end
