require a SQL query to split a column into 3 columns : I have designed a table named as 'customeradd'. Till now no data has been entered into it.
Can anyone suggest me any SQL query to split 'customeradd'. column into 3 sub columns so that it looks like this in the schema:-

**customeradd**
| A | B | C |
|   |   |   |

A,B,C are 3 sub columns of customeradd column

Thanks a lot.
