示例1: ChangeColumn

		public override void ChangeColumn(string table, Column column)
		{
			if (!ColumnExists(table, column.Name))
			{
				Logger.Warn("Column {0}.{1} does not exist", table, column.Name);
				return;
			}

		    var existingColumn = GetColumnByName(table, column.Name);
		    
            column.Name = existingColumn.Name; // name might have different case.

			string tempColumn = "temp_" + column.Name;
			RenameColumn(table, column.Name, tempColumn);

			// check if this is not-null
			bool isNotNull = (column.ColumnProperty & ColumnProperty.NotNull) == ColumnProperty.NotNull;

			// remove the not-null option
			column.ColumnProperty = (column.ColumnProperty & ~ColumnProperty.NotNull);

			AddColumn(table, column);
			ExecuteQuery(String.Format("UPDATE {0} SET {1}={2}", table, Dialect.Quote(column.Name), tempColumn));
