I have a table where i have a multitude of columns.
idnum,diagnosiscode,order_of_diagnosis,POA_Flag

000000000000001|234|01|Y
000000000000001|800|02|Y
000000000000001|E344|03|Y
000000000000001|667|04|Y
000000000000001|900|05|Y
000000000000001|234|06|Y
000000000000001|800|07|Y
000000000000001|E344|08|Y
000000000000001|667|09|Y
000000000000001|900|10|Y
000000000000001|288|11|Y
000000000000001|4800|12|Y
000000000000001|G887|13|Y
000000000000001|667|14|Y
000000000000001|900|15|Y

I am trying to write a select distinct query that will return each group with ONLY unique diagnosiscode, and renumbering as applicable so they stay in thier original order.

Thanks for any all assistance in advance.

Here is the example content prior to removing the duplicate values

000000000000001|234|01|Y
000000000000001|800|02|Y
000000000000001|E344|03|Y
000000000000001|667|04|Y
000000000000001|900|05|Y
000000000000001|234|06|Y - to be removed as redundant
000000000000001|800|07|Y - to be removed as redundant
000000000000001|E344|08|Y - to be removed as redundant
000000000000001|667|09|Y - to be removed as redundant
000000000000001|900|10|Y - to be removed as redundant
000000000000001|288|11|Y
000000000000001|4800|12|Y
000000000000001|G887|13|Y
000000000000001|667|14|Y - to be removed as redundant
000000000000001|900|15|Y - to be removed as redundant

This would be the final output format:

000000000000001|234|01|Y
000000000000001|800|02|Y
000000000000001|E344|03|Y
000000000000001|667|04|Y
000000000000001|900|05|Y
000000000000001|288|06|Y (New Value and in ordinal order)
000000000000001|4800|07|Y
(New Value and in ordinal order)
