我已经开始从事现金券项目。当我单击“提交”按钮时,将出现一个弹出框,并显示“ Invalid Object voucher_table”。 我该怎么办?
private void bunifuFlatButton1_Click(object sender, EventArgs e)
{
string con = ConfigurationManager.ConnectionStrings["mydb"].ConnectionString;
SqlConnection sqlcn = new SqlConnection(con);
sqlcn.Open();
try
{
SqlCommand cmd = new SqlCommand("INSERT INTO voucher_table(customerID, planName, days, planAmount, validFrom, validTo, amountInWords, date, rupees) values(@customerID, @planName, @days, @planAmount, @validFrom, @validTo, @amountInWords, @date, @rupees)", sqlcn);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@customerID", customerID.Text);
cmd.Parameters.AddWithValue("@planName", planName.Text);
cmd.Parameters.AddWithValue("@days", days.Text);
cmd.Parameters.AddWithValue("@planAmount", planAmount.Text);
cmd.Parameters.AddWithValue("@validFrom", validFrom.Text);
cmd.Parameters.AddWithValue("@validTo", validTo.Text);
cmd.Parameters.AddWithValue("@amountInWords", amountInWordsTextBox1.Text + amountInWordsTextBox2.Text);
cmd.Parameters.AddWithValue("@date", date.Text);
cmd.Parameters.AddWithValue("@rupees", rupees.Text);
int i = cmd.ExecuteNonQuery();
if (i > 0)
{
MessageBox.Show("Voucher Created Successfully");
SqlCommand cmd1 = new SqlCommand("select max(primaryNo) from voucher_table", sqlcn);
SqlDataReader dr1 = cmd1.ExecuteReader();
if (dr1.Read())
{
MessageBox.Show("Your Voucher No is '" + dr1.GetInt32(0) + "'Your Voucher is Created Successfully!");
Voucher_Successful success = new Voucher_Successful();
success.ShowDialog();
}
this.Close();
}
else
{
MessageBox.Show("An Error Occured... Voucher Not Created");
}
sqlcn.Close();
}
catch (SqlException ex)
{
MessageBox.Show(ex.Message);
}

我认为您不在正确的数据库中(即,SQL命令找不到voucher_table)。 检查您所连接的数据库中是否确实存在voucher_table。
我发现了与您类似的问题,您也可能在那找到帮助:SQL Server: invalid object name in query execution
