Max value in a column
Hi,
My requirement is to find the max value of a column and the add that max value will be populated against each row in the dataset as a new column.
For e.g.
Existing dataset
| col1 | col2 | col3 |
| 1 | 23 | ABC |
| 1 | 17 | GDFT |
| 1 | 25 | HDG |
| 1 | 35 | HDI |
here 35 is the max value for col2. hence it needs to get populated in a new column. new dataset will be as below
| col1 | col2 | col3 | col4(New Column) |
| 1 | 23 | ABC | 35 |
| 1 | 17 | GDFT | 35 |
| 1 | 25 | HDG | 35 |
| 1 | 35 | HDI | 35 |
please help me to get away with this problem. Thanks in advance
Regards,
Deepak

From the data you are showing it appears that col1 has the same value all the way down.
