multicolumn

I have Table "MultiCol" as below

Name LibraryID RegisterID EngineerID
Rahul 1002      4521       4854
Ajay  5072      3151       4833
Vimal 4532      4531       4354

I want to insert the Rahul's all IDs in the "SingleCol" table(shown below) which is having only one Column named "IDS"

So I want the Result as shown below

Table "SingleCol"

Which query pattern will be most efficient in terms of time and space?
