I have a table with multiple rows per unique ID, and some columns which reference "flags" (basically a 1 or 0) that something has occurred relative to that ID. Due to the way the data is structured, there can bemultiple instances of a flag showing up for each ID:
ID ColA ColB ColC
31 1 1 0
31 0 1 0
31 1 1 0
144 1 0 0
144 1 0 0
144 1 0 0
26 0 0 0
26 0 0 1
But I don't care if the "1" shows up multiple times for each ID --- I want to add three columns which basically indicates, for each ID, whether or not a flag has occurred there ever (as indicated by the "1"). Call them ColA_Flag, ColB_Flag, and ColC_Flag.
So for ID 31, there would be a "yes" for Col A amd Col B, but a "no" for Col C.
So it would look like this:
ID ColA ColB ColC FlagA FlagB FlagC
31 1 1 0 Yes Yes No
31 0 1 0 Yes Yes No
31 1 1 0 Yes Yes No
144 1 0 0 Yes No No
144 1 0 0 Yes No No
144 1 0 0 Yes No No
26 0 0 0 No No Yes
26 0 0 1 No No Yes
Any help is appreciated!
