How to add new column to an existing table

[yoyali]

Hi everyone,
I need help in this matter. I have this form in which the user insert his details, and chose which detail to add and which not and he can add a new field by his own which doesn't exist before. So this new field is a new column, so I just want to know how to add this column into an existing table.
I'm using sql server 2000
Many Thanx
Yoya :)

INSERT INTO ur_table (field1,field2,field3) VALUES ('value1','value2', 'value3')

ALTER TABLE [myTable] ADD [MyColumn] varchar(30)
