I need to update records in one table with info from another inner joined by an ID field which is case sensitive. Additionally i need to drop the last three digits from the ID on one table.
I used this select query to test and it is not working, any ideas?
SELECT Copy_All_Amhsi_combo.acct_id, jn179238.sfaccid, Copy_All_Amhsi_combo.VIS_N, jn179238.idnumber
FROM JN179238 INNER JOIN Copy_All_Amhsi_combo ON Copy_All_Amhsi_combo.acct_id = left(jn179238.sfaccid,15)
WHERE Asc([Copy_All_Amhsi_combo].[acct_id])=Asc([jn179238].[sfaccid]) ;
