我收到以下错误ExecuteNonQuery()
"String or binary data would be truncated. The statement has been terminated."
问题是要发送的变量比数据库中的变量大。我正在使用以下代码：
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//GridViewRow row = GridView1.SelectedRow;
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
var Username = (Label)row.FindControl("Label3");
var Password = (Label)row.FindControl("Label4");
var Email = (Label)row.FindControl("Label5");
// var ID_Inscricao = ((Label)row.FindControl("Label1")).Text;
var ID_Inscricao = ((Label)row.FindControl("Label1")).Text;
SqlConnection sqlConn = new SqlConnection(ConfigurationManager.ConnectionStrings["FormacaoConnectionString"].ToString());
SqlCommand sqlComm = new SqlCommand();
sqlComm = sqlConn.CreateCommand();
sqlComm.Parameters.Add("@Username", SqlDbType.Text);
sqlComm.Parameters.Add("@Password", SqlDbType.Text);
sqlComm.Parameters.Add("@Email", SqlDbType.Text);
sqlComm.Parameters.Add("@ID_Inscricao", SqlDbType.Int);
sqlComm.Parameters["@Username"].Value = Convert.ToString(Username);
sqlComm.Parameters["@Password"].Value = Convert.ToString(Password);
sqlComm.Parameters["@Email"].Value = Convert.ToString(Email);
sqlComm.Parameters["@ID_Inscricao"].Value = Convert.ToInt32(ID_Inscricao);
string sql = "INSERT INTO Utilizadores (Username, Password, Email, ID_Inscricao) VALUES (@Username, @Password, @Email, @ID_Inscricao)";
sqlComm.CommandText = sql;
sqlConn.Open();
sqlComm.ExecuteNonQuery();
sqlConn.Close();
}
