当我尝试向表 pay_cheque 插入任何帮助时出现此错误
private void btnadd_Click(object sender, EventArgs e)
{
string s = "insert into pay_cheque values('Sai','Sai','Sai','Sai','10.2','1989/2/3','Sai')";
SqlConnection con = new SqlConnection("server=.;Data Source=.;Initial Catalog=Book;Integrated Security=True");
SqlDataAdapter da = new SqlDataAdapter(s, con);
DataSet ds = new DataSet();
da.Fill(ds, "x");
dataGridView1.DataSource = ds.Tables[0];
}
