Teradata conversion to hive sql


I am trying to convert the below teradata sql to hive sql but am getting error near the end line :ParseException line 83:6 missing ) at 'qualify' near 'qualify' line 83:14 missing EOF at 'row_number' near 'qualify'

I am very new to hive . Any help would be greatly appreciated

Solution

  • QUALIFY is proprietary Teradata syntax, you must rewrite it using a Derived Table:

    select customer_id         tier_cust_id,
    
        support_segment     tier_suppt_seg
     from (select c.customer_id,
                c.primary_email_name,
                am_id,
                am_name, 
                c.customer_first_name ,
                c.customer_last_name ,
                c.customer_primary_residence   ,
                c.CUSTOMER_USER_GROUP,
                c.customer_flag1,
     case when c.customer_primary_residence not in ('US', 'MX', 'CA') then       'ROW'
                     when ent.cust_id = bam.cust_id then 'Enterprise Support'
