title: Meaning of square brackets [] in MS-SQL table designer?
body: <p>I have a copy of an existing database with existing records. when i was playing around with the table designer and noticed some of the column names have [] around them. they all seem to be arbitrary typed (float, datetime, netext, nvarchar etc) and there is nothing in column properties that gets rid of the []. I tried to rename delete the [] but it reappaears as soon as I exit edit. </p>
  
  <p>according to <a href="https://stackoverflow.com/questions/1379913/sql-server-2005-puts-square-brackets-around-column-name">this</a> post, it is a keyword column for xml columns? but none of those columns are xml columns. Would someone kindly explain the purpose of this to a ms-sql newbie? thanks</p>
