Creating Equal number of records based on a column.

Hi Guys,

The Table i am talking about it is as follows.

Col1 Col2 Col3 Col4

Col1 can have 5 different values (1,2,5,6,7).

Based on the Col2, i will see how many such values are present for Col1. Then i have to create the remaining records with col3 and col4 as '99'.

For an example,

1 AA 87 98
2 AA 77 56
6 BB yu io


So, for AA i have to add 3 more records, with value for the first record as 5,6,7 and the remaining col3 and col4 as '99'

For BB, we have to add 4 more records with value for the first record as 1,2,5,7 and the remaining col3 and col4 as '99'.

Can somebody help me out with this.

Cheers!!!
