I have a database (i use MS ACCESS) I have this insert code, I can read data but got error when writing, I follow instruction but it didn't work here is my code
OleDbConnection con = new OleDbConnection(@" provider=Microsoft.ace.Oledb.12.0; data source=\\sisc-erelim\4_Printing\VTDB\DB\VirginiTEADB2.accdb; Persist Security Info=False");
private void button1_Click(object sender, EventArgs e)
{
try
{
OleDbCommand cmd = new OleDbCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "INSERT INTO Accountstbl (Username, Password)" + "VALUES ('" + textBox1.Text + "','" + textBox2.Text + "')";
cmd.Parameters.AddWithValue("@Username", textBox1.Text);
cmd.Parameters.AddWithValue("@Password", textBox2.Text);
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
}
catch (Exception ex)
{
textBox1.Text = ex.ToString();
}
And I always got this error,
System.Data.OleDb.OleDbException: Syntax error in INSERT INTO statement.

You defined @Username
and @Password
parameters but you never used in your sql command.
How about?
cmd.CommandText = "INSERT INTO Accountstbl (Username, [Password]) VALUES (@Username, @Password)";
cmd.Parameters.AddWithValue("@Username", textBox1.Text);
cmd.Parameters.AddWithValue("@Password", textBox2.Text);
cmd.Connection = con;
con.Open();
cmd.ExecuteNonQuery();
Also you should use Password
in square brackets on your sql command like [Password]
because it is a reserved keyword
in MS Access.
If you don't this can cause an error like;
Incorrect syntax near the keyword "Password"
