I want to create a grouping column based on two columns and certain criteria. The scenario: Below is the given table with column A & B

| HOST-A02BF7E1B9ADA36D | HOST-7453A7E317FCF4AF |
First the first row value of column A has to be considered.
1.Lets say HOST-7344649A8D974E74 then we have to give all the corresponding values of A in column B a particular group name.The corresponding values of HOST-7344649A8D974E74 are HOST-0788564003D72AEF, HOST-A02BF7E1B9ADA36D,HOST-54AA0D8B5401A1C2,HOST-DE6F9EC80D4D7C58,HOST-7453A7E317FCF4AF these values will be given a particular group value.Lets say Group-4.
2. Now the first corresponding value in column B of Column A : HOST-0788564003D72AEF will be considered as the value of column A and all the corresponding values of HOST-0788564003D72AEF in column be will be named as Group-4. This loop will continue for all the values present in column B for the Column A value of HOST-7344649A8D974E74.
3.The above 2 steps will continue for each unique value in column A and its corresponding values.
4.There shouldn't be any duplicates created.
The result :
| Group | A | B |
| Group-4 | HOST-7344649A8D974E74 | HOST-0788564003D72AEF |
| Group-4 | HOST-7344649A8D974E74 | HOST-A02BF7E1B9ADA36D |
