Question on C# strings

ram a

Hi All,
Could some one explain me the difference between the 2 lines below.
string sql = @"SELECT columnname " +
      @"FROM tablename " +
      @"WHERE ID = '" + settingId + "' ";

string sql = "SELECT columnname " +
      "FROM tablename " +
      "WHERE ID = '" + settingId + "' ";

Does '@' in the first statement makes any difference?

Just to add into that:

The @ symbol tells the string constructor to ignore escape characters and line breaks. The following two strings are therefore identical:
string p1 = "\\\\My Documents\\My Files\\";
string p2 = @"\\My Documents\My Files\";

@ stands for Escap sequence

if there is ' / ' then you should use @ before string

other wise not
