Compare date fields in SQL server
- by huslayer
Hi all,
I've a flat file that I cleaned the data out using SSIS, the output looks like that :
MEDICAL ADMIT PATIENT PATIENT DATE OF DX
REC NO DATE NUMBER NAME DISCHARGE Code DRG #
123613 02/16/09 12413209 MORIBALDI ,GEMMA 02/19/09 428.20 988
130897 01/23/09 12407193 TINLEY ,PATRICIA 01/23/09 535.10 392
139367 02/27/09 36262509 THARPE ,GLORIA 03/05/09 562.10 392
141954 02/25/09 72779499 SHUMATE ,VALERIA 02/25/09 112.84 370
141954 03/07/09 36271732 SHUMATE ,VALERIA 03/10/09 493.92 203
145299 01/21/09 12406294 BAUGH ,MARIA 01/21/09 366.17 117
and the report (final results) attached in the screen shot from the final excel report.
so what's happening is IF the same name or same account number is duplicate, that means the patient has entered the hospital again and needs to be included in the report.

what I need to do is...
Eliminate any rows that is NOT duplicate (not everybody in this file has been admitted again)
and compare the dates to get the ReAdmitdate and ReDischargedate
I dumped the data into a SQL table and trying to compare the dates to figure out "ReAdmitdate" and "ReDischargedate"
any help is appreciated.
Thanks
