Another way to do it programatically

另一种编程方式。

EXEC sp_updateextendedproperty 
@name = N'MS_Description', @value = 'Your description',

EXEC sp_addextendedproperty 
    @name = N'MS_Description', @value = 'This is the description of my column',
    @level0type = N'Schema', @level0name = 'dbo',
    @level1type = N'Table', @level1name = 'MyTable', 
    @level2type = N'Column', @level2name = 'MyColumn'
