Solution 2

You should rewrite you whole sql Using Parameterized queries to prevent SQL Injection Attacks in SQL Server[^]
That will also avoid the messy and confusing quotes problem.

Check the no.of columns and values your passing are same count and all are string datatype?

try this

string query = "insert into Reservation (@Code, @Status,@Guest Name,@Guest Email,@Guest Phone No)values( '" +textBox1.Text+ "',"' + comboBox2.SelectedValue + "','" +textBox1.Text+ "','" +textBox1.Text+ "','" +textBox1.Text+ "')";

You are missing some quotes near values and combobox

try this

C#

string query = ("insert into Reservation (@Code, @Status,@Guest Name,@Guest Email,@Guest Phone No,@Checkin,@Check Out,@Adult No,@Child No,@Infant No,@Net Total,@Discount,@Tax,@Total,@Paid)+values( '" +textBox1.Text+ "','" + comboBox2.SelectedValue + "','" +textBox1.Text+ "','" +textBox1.Text+ "','" +textBox1.Text+ "','" +textBox1.Text+ "','" +textBox1.Text+ "')");
