表定义是
CREATE TABLE [dbo].[dept]
(
[dept_id] INT IDENTITY (100, 1) NOT NULL,
[dept_name] VARCHAR (25) NULL,
[emp_no] INT NULL,
[location] VARCHAR (50) NULL,
[project_no] INT NULL,
PRIMARY KEY CLUSTERED ([dept_id] ASC)
);
答案 0 :(得分:0)
您是否尝试过使用
d["emp_no"]=int.Parse(textBox2.Text);
而不是
d["emp_no"]=textBox2.Text;
表示整数列?
