I added a column to an existing table, so there should be nothing (actually the default, I suppose) in this column for all existing rows. However if I do: select new_column from modified_table ; I get the total number of rows in the table, but the lines on the screen have no visible characters. I was expecting these to be nulls, and this select to return nothing. How can i make these "invisible" characters visible? -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin
