Image location

[mujeesh]

hi

I am using Mysql database.

I am trying to insert an image location in to my database but its not saving properly.if i choose an image "E:\Production\ Images\image001 .jpg"

its saving like this "E:ProductionIm agesimage001.jp g"

//this is my code

private void button2_Click(object sender, EventArgs e)
{
OpenFileDialog open = new OpenFileDialog();

open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";

if (open.ShowDialog() == DialogResult.OK)
{

pictureBox1.Image = new Bitmap(open.FileName);

//I am using a class

c.cmd = new MySqlCommand("SELECT COUNT(*) FROM image_table;", c.conn());
maxVal = Convert.ToInt32(c.cmd.ExecuteScalar().ToString());


c.conn();




string query = "INSERT INTO image_table (IMAGE_NO, IMAGE_LOCATION, ASSIGN_DATE, ASSIGN_TO, ASSIGN_BY) VALUES ('" + (maxVal + 1) + "', '" + open.FileName+ "', '" + this.Assign_date.Value + "','" + Class1.AssignTo + "','" + Class1.userName + "')";

{
c.cmd = new MySqlCommand(query, c.conn());

//Execute command
c.cmd.ExecuteNonQuery();
c.conn().Close();

}

}
}

Please suggest a method to solve this problem.I am stuck,the code isn't work.

Have you tried using parameters instead of concatenating the values to a query-string?
Like "INSERT INTO tabXy (FieldX) VALUES (@valueX)" and passing a @valueX-parameter.
I don't know how MySqlCommand-class works, but I always use that way with SqlCommand-class.

Second you can try to output your query-string after building it to see if it's already incorrected before it gets passed to new MySqlCommand().

I believe that your problem is with MySQL, not C#. According to my SQL pocket reference, MySQL and PostgreSQL both recognize the '\' character as an escape character by default. You will have to double-up on your '\' characters before sending them off to MySQL, or you can explicitly specify the escape character in your SQL statement using the 'ESCAPE' keyword.
