Query on 3 tables

Question

Hi,
I need to retrieve data from 3 different tables. I've got a card number as input which I can use to retrieve the account number which is the primary key of the to other tables. For example:
Table 1
Col 1 (input PK)
Col 2 (Fk)
Col 3
Table 2
Col 1
Col 2 (PK)
Col 3
Table 3
Col 1
Col 2 (PK)
Col 3
This is the query that I created but it returns 2 identical lines:
SELECT p.PLAS_EMBOS_LINE_2_1142281,
       c.CUST_CUSTOMER_NAME_1_1142239,
        c.CUST_LANGUAGE_CODE_11422E3,
       a.ADDR_ADDR_LINE_0_1142241,
        a.ADDR_ZIP_FIRST_5_11422BM,
        a.ADDR_ADDR_CITY_1142244,
        a.ADDR_ADDR_CNTRY_CODE_114250
FROM od_nfr_plastic p, od_nfr_customer c, od_nfr_address a
WHERE c.CUST_ACCOUNT_NUMBER_1142237 = p.PLAS_ACCOUNT_NUMBER_1142237
  AND a.ADDR_ACCOUNT_NUMBER = p.PLAS_ACCOUNT_NUMBER_1142237
  AND p.PLAS_NUMBER_1_11422B2 = '5413275482825807'Regards,

Answer 1

you can try using the DISTINCT:
SELECT DISTINCT
       p.PLAS_EMBOS_LINE_2_1142281,
       c.CUST_CUSTOMER_NAME_1_1142239,
       UST_LANGUAGE_CODE_11422E3,
       a.ADDR_ADDR_LINE_0_1142241,
       a.ADDR_ZIP_FIRST_5_11422BM,
       a.ADDR_ADDR_CITY_1142244,
       a.ADDR_ADDR_CNTRY_CODE_114250
  FROM od_nfr_plastic  p,
       od_nfr_customer c,
       od_nfr_address  a
WHERE c.CUST_ACCOUNT_NUMBER_1142237 = p.PLAS_ACCOUNT_NUMBER_1142237
   AND a.ADDR_ACCOUNT_NUMBER         = p.PLAS_ACCOUNT_NUMBER_1142237
   AND p.PLAS_NUMBER_1_11422B2       = '5413275482825807'note: untested
if you can post some sample data and output will help us understand your requirement.
