I am trying to insert data into a table in MS Access. I keep getting the error Missing semicolon (;) at end of SQL statement. or a different error saying that i my Insert query needs to have a value or table in it. Here is my code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.OleDb;
using System.Data.SqlClient;
namespace MiddleWare
{
public partial class Sales : Form
{
public Sales()
{
InitializeComponent();
}
private void btnUpdate_Click(object sender, EventArgs e)
{
int empId = int.Parse(txtEmpID.Text);
string cmdText = @"INSERT INTO [Sales]
([Printers], [Ink], [Paper])
VALUES (@Printers,@Ink,@Paper)
SELECT @EmpID FROM (Emplopyee)";
using (OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\cp-stud-nas1\users\mat72462\Documents\SalesData.accdb"))
using (OleDbCommand cmd = new OleDbCommand(cmdText, con))
{
con.Open();
cmd.Parameters.AddWithValue("@Printers", OleDbType.VarWChar).Value = txtPrinters.Text;
cmd.Parameters.AddWithValue("@Ink", OleDbType.VarWChar).Value = txtInk.Text;
cmd.Parameters.AddWithValue("@Paper", OleDbType.VarWChar).Value = txtPaper.Text;
cmd.Parameters.AddWithValue("@EmpID", OleDbType.VarWChar).Value = txtEmpID.Text;
cmd.ExecuteNonQuery();
cmd.Parameters.Clear();
cmd.Parameters.AddWithValue("@EmpID", txtEmpID.Text);
cmd.CommandText = "SELECT [Total Sales] FROM Sales WHERE EmpID=@EmpID";
string result = cmd.ExecuteScalar().ToString();
MessageBox.Show(result);
}
}
private void Sales_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'DataSet1.DataTable1' table. You can move, or remove it, as needed.
this.DataTable1TableAdapter.Fill(this.DataSet1.DataTable1);
}
private void btnReport_Click(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\cp-stud-nas1\users\mat72462\Documents\SalesData.accdb");
{
this.DataTable1TableAdapter.Fill(this.DataSet1.DataTable1);
this.reportViewer1.RefreshReport();
}
}
}
}
You should seperate the queries by semicolon
string cmdText = @"INSERT INTO [Sales]
([Printers], [Ink], [Paper])
VALUES (@Printers,@Ink,@Paper);
SELECT @EmpID FROM (Emplopyee)";
Also you can't pass the column name as parameter. In that case use dynamic query.
you should change the query to this:
string cmdText = @"INSERT INTO [Sales]
([Printers], [Ink], [Paper], [EmpID])
VALUES (@Printers,@Ink,@Paper,
SELECT EmpID FROM (Employee) )";
It most likely should read:
string cmdText = @"INSERT INTO [Sales]
([Printers], [Ink], [Paper], [EmpID])
VALUES (@Printers, @Ink, @Paper, @EmpID)";
The "cmd.Paramter.AddWithValue" are unnecessary.
Try formatting your cmdText as
cmd = "INSERT INTO [Sales] ([Printers], [Ink], [Paper])
VALUES (" + txtPrinters.Text + " ," + txtInk.Text + ", " + txtPaper.Text + ")
This clears up confusion of "cmd.Paramter.AddWithValue" duplicating or overriding values.
Rewritten btnUpdate_Click (also not sure if Emplopyee is a typo or not)
private void btnUpdate_Click(object sender, EventArgs e)
{
using (OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\cp-stud-nas1\users\mat72462\Documents\SalesData.accdb"))
using (OleDbCommand cmd = new OleDbCommand(cmdText, con))
{
con.Open();
cmd = "INSERT INTO [Sales] ([Printers], [Ink], [Paper]) VALUES (" + txtPrinters.Text + " ," + txtInk.Text + ", " + txtPaper.Text + ") SELECT " + textEmpID.Text + " FROM (Emplopyee)";
cmd.ExecuteNonQuery();
cmd.CommandText = "SELECT [Total Sales] FROM Sales WHERE EmpID=@EmpID";
string result = cmd.ExecuteScalar().ToString();
MessageBox.Show(result);
}
