title: SQL Server int length property
body: <p>I've got a SQL Server database. One of my tables has a column called <code>id</code> which is incremented automatically when I create a new project in a program that is connected to the database. Right now the highest id is 9175. Now I'm worried that the highest possible is is 9999. I checked the properties of the id column, see the below picture.</p>
  
  <p>The "Length" property says 4. What does this mean for an int? Does it mean that the database will not accept an id of 10000? How can I find out?</p>
