使用正确的MS Access cmd命令插入SQL可更新查询

Question

当我在另一台计算机上运行时，访问数据库查询失败

Microsoft Word 2013 Visual Studio 2013 Windows 8.1（64位）

在另一台计算机上时，同一查询在下面运行配置

Microsoft Word 2010 Visual Studio 2010 Windows 7（32位）

下面的查询

 con.Open();

            string cb = "insert Into Salcmd = new sqles(InvoiceNo,InvoiceDate,CustomerID,SubTotal,VATPercentage,VATAmount,GrandTotal,TotalPayment,PaymentDue,Remarks) VALUES ('" + txtInvoiceNo.Text + "',#" + dtpInvoiceDate.Text + "#,'" + txtCustomerID.Text + "'," + txtSubTotal.Text + "," + txtTaxPer.Text + "," + txtTaxAmt.Text + "," + txtTotal.Text + "," + txtTotalPayment.Text + "," + txtPaymentDue.Text + ",'" + txtRemarks.Text + "')";
            cmd = new OleDbCommand(cb);
            cmd.Connection = con;
            cmd.ExecuteReader();
            if (con.State == ConnectionState.Open)
            {
                con.Close();
            }
            con.Close();

查询依赖关系有问题吗，请让我知道

Answer 1

您的INSERT SQL语句包含语法错误：

string cb = "insert Into Salcmd = new sqles(InvoiceNo,InvoiceDate,CustomerID,SubTotal,VATPercentage,VATAmount,GrandTotal,TotalPayment,PaymentDue,Remarks) VALUES ('" + txtInvoiceNo.Text + "',#" + dtpInvoiceDate.Text + "#,'" + txtCustomerID.Text + "'," + txtSubTotal.Text + "," + txtTaxPer.Text + "," + txtTaxAmt.Text + "," + txtTotal.Text + "," + txtTotalPayment.Text + "," + txtPaymentDue.Text + ",'" + txtRemarks.Text + "')"

可能应该是：

string cb = "INSERT INTO sqles(InvoiceNo,InvoiceDate,CustomerID,SubTotal,VATPercentage,VATAmount,GrandTotal,TotalPayment,PaymentDue,Remarks) VALUES ('" + txtInvoiceNo.Text + "',#" + dtpInvoiceDate.Text + "#,'" + txtCustomerID.Text + "'," + txtSubTotal.Text + "," + txtTaxPer.Text + "," + txtTaxAmt.Text + "," + txtTotal.Text + "," + txtTotalPayment.Text + "," + txtPaymentDue.Text + ",'" + txtRemarks.Text + "')"

另外，请尝试： cmd.ExecuteNonQuery()而不是阅读器。

希望这会有所帮助。
