Query 2 Tables Inner Joins

[JayKappy]

I have 2 stand alone tables in the File Geodatabase. (Test_SignStandalone_3 and Test_SignHistorical_3)
I need to select and delete the duplicate records in one table (Test_SignHistorical_3) where they match the other table (Test_SignStandalone_3) via numerous fields....

I exported the data out to Access and was able to run the SQL Query below and was successful...

SELECT Test_SignStandalone_3.*
FROM Test_SignHistorical_3 INNER JOIN Test_SignStandalone_3 ON (Test_SignHistorical_3.NewSupID = Test_SignStandalone_3.New_SupID) AND (Test_SignHistorical_3.NOTES = Test_SignStandalone_3.NOTES) AND (Test_SignHistorical_3.CONDITION = Test_SignStandalone_3.CONDITION) AND (Test_SignHistorical_3.WORK_ORDER_NUMBER = Test_SignStandalone_3.WORK_ORDER) AND (Test_SignHistorical_3.WHY = Test_SignStandalone_3.WHY) AND (Test_SignHistorical_3.WHO = Test_SignStandalone_3.WHO) AND (Test_SignHistorical_3.COMPLETED = Test_SignStandalone_3.COMPLETED) AND (Test_SignHistorical_3.ACTIVITY = Test_SignStandalone_3.ACTIVITY) AND (Test_SignHistorical_3.SHEETING_M = Test_SignStandalone_3.SHEETING_M) AND (Test_SignHistorical_3.WHEN_STARTED = Test_SignStandalone_3.WHEN_STARTED) AND (Test_SignHistorical_3.WHEN_ENDED = Test_SignStandalone_3.WHEN_ENDED) AND (Test_SignHistorical_3.New_SignID = Test_SignStandalone_3.New_SignID);

My question is how to I accomplish this in ArcGIS and my File Geodatabase.
Thanks

What version of ArcGIS are you using?

[JayKappy]

10.0  not ready to move to 10.1 yet due to conflict with another software.

Have you tried this with File Geodatabase? We added INNER JOIN at 10.0. You have to use code and an IQueryDef.

seems like this is far more challenging than it should be.  Lacking some serious DB tools.
couple minutes out of something like Access...
* Think I am going to import into FGDB
* Create a field
* Go into Access and run the query and update the records that match my query
* Go back into GIS and delete those records.

Thanks
