| 1st Row All Column Values were Same So Its the Parent Node and Its Parent Id will be 0.2nd Row PID 102 1st Column is AA and Other were AB, Its the Child for 1st row and the same for PID 106 1st Col is AA and Others were AC. Here the PArentID will be 101.The same have to Check for All Rows, If all Row Values were same Then its PArent.After 1st Column If other Column values were same Then its the Child for 1st Parent.And the Same Check for Other Columns.Regards,Kalai |
