Netezza: While creating external table, column name is duped with same data type, need to know the reason -


i creating external table in netezza. after table creation when describing it, can see column duped 4 times. looks strange me happening.

example:

    create external table test '/nzscratch/kapish/69314.082.000/tv_daily_audit_results.txt'             using(delim '|' format 'text'            )     select         b.card_acceptor_id mid,         a.div_no card_div_no,         c.div_name acct_type,         a.acct_id,         a.tran_text,         substr(a.tran_text, 24, 13) merchant_city,         substr(a.tran_text, 37, 2) merchant_state,         b.merchant_zip_cd,         a.post_date,         a.tran_cd,         a.gl_origin_cd,         a.tran_amt,         a.merchant_cat_cd             pstdtr_pstd_trans a,         pstdrt_rtain_rtns b,         divdef_div_def_v c             a.acct_id = b.acct_id         , a.reference_no = b.reference_no         , a.tran_date = b.tran_date         , a.div_no = c.div_no         , a.div_no in (232, 234, 235, 237, 273, 275, 276, 278)         , post_date >= (current_date - 2)         , gl_origin_cd not in (232, 234, 235, 237, 273, 275, 276, 278)      system.admin(admin)=> \d test        external table "tv_daily_audit_results"     attribute    |         type          | modifier -----------------+-----------------------+----------  mid             | character(15)         |  mid             | character(15)         |  mid             | character(15)         |  mid             | character(15)         |  card_div_no     | smallint              | not null  card_div_no     | smallint              | not null  card_div_no     | smallint              | not null  card_div_no     | smallint              | not null  acct_type       | character(30)         |  ..  ..  ..  merchant_cat_cd | integer               |  merchant_cat_cd | integer               |  merchant_cat_cd | integer               |  merchant_cat_cd | integer               |  dataobject - 'c:\winsql jobs\daily tv audit\tv_daily_audit_results.txt'  dataobject - 'c:\winsql jobs\daily tv audit\tv_daily_audit_results.txt'  dataobject - 'c:\winsql jobs\daily tv audit\tv_daily_audit_results.txt'  dataobject - 'c:\winsql jobs\daily tv audit\tv_daily_audit_results.txt'  adjustdistzeroint   -  bool style          - 1_0 .  .  decimaldelim        -  disablenfc          -  includeheader       - 

now sure reason it. if 1 can me, great.

this appears same bug/issue recognized in this question, has been resolved subsequent fixes/releases. should contact support fix.

the table should function normal, despite odd report catalog.
