Question

I’m trying to execute my login form using a SQL Server database.. but I’m getting an error saying

Incorrect syntax near ‘‘

The line where I am getting the error is:

objda.Fill(objds, "adm");

and my code is:

public partial class Form1 : Form
{
    int total;
    SqlConnection objc;
    string c = "data source=.; initial catalog=student; integrated security=SSPI";
    SqlDataAdapter objda;
    DataSet objds;
    SqlCommand objcmd;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
    }

    private void button1_Click(object sender, EventArgs e)
    {
        if (objc != null)
        {
            objc.Open();
        }
        objcmd = new SqlCommand("select * form adm where Name= ' " + textBox1.Text + "',pass = ' " + textBox2.Text + "'", objc);
        if (objc != null)
        {
            objc.Close();
        }
        objc = new SqlConnection(c);
        objcmd = new SqlCommand("search * from adm", objc);
        objda = new SqlDataAdapter(objcmd.CommandText, objc);
        objds = new DataSet();
        objda.Fill(objds, "adm");

        total = Convert.ToInt32(objds.Tables["adm"].Rows.Count);
        if (total > 0)
        {
            MessageBox.Show("welcome");
            Class1.login = textBox1.Text;
            Form2 f2 = new Form2();
            this.Hide();
            f2.Show();
        }
        else
        {
        }

What should I do?

Where is the problem?

Answer 1

you have forgotten to place “And” between two conditions and miss spelled form keyword .

objcmd = new SqlCommand("select * from adm where Name= '" + textBox1.Text + "' And pass = '" + textBox2.Text + "'", objc);

by the way you should use parameters to avoid sql injection vulnerability
