Question

I have a form which inserts data into a database.

There are certain fields that are not always going to be needed.
When I leave these blank in my code I get a error saying.

Column name or number of supplied values does not match table
definition.

This is how I have the database setup. SQL Server 2008

[youthclubid]
[youthclubname]
[description]
[address1]
[address2]
[county]
[postcode]
[email]
[phone]

Here is the code that I have connecting to the database and doing the insert.

connection.Open();
cmd = new SqlCommand("insert into youthclublist values ('" + youthclubname.Text + "', '" + description.Text + "','" + address1.Text + "','" + address2.Text + "', '" + county.Text + "', '" + postcode.Text + "', '" + email.Text + "', '" + phone.Text + "')", connection);
cmd.ExecuteNonQuery();

Answer 1

You need to tell SQL server that which field you want to insert like

        insert into youthclublist(youthclubid, youthclubname, ....) values ('" + youthclubname.Text + "', '" + description.Text + "'.....

and you are fine.
