Question

I have a Pl/SQL query that pull all records from the 3 tables. That is good. Now I want pull last 24 updated records from 2 table (tbl_constit, tbl_email).

See below actual query

SELECT DISTINCT c.constit_id AS constitid,
               REPLACE (c.in_labelname, 'None', '') AS fullname,
               c.firstname AS firstname, c.lastname AS lastname,
               c.indiv_title AS title, e.e_addr AS email,
              'InActive' AS status                               
          FROM tbl_constit cn, tbl_email e,tbl_catcod s
         WHERE c.constit_id = e.constit_id
           AND c.constit_id = s.constit_id(+)
           AND e.e_type = 'EMAIL'
           AND e.e_default = '1'
           AND s.cat_code IN ('SPEMU', 'SPENM')              
      ORDER BY c.constit_id;

tables tbl_constit cn, tbl_email e has ‘CHGD_DT’ field.

This date field change when record is updated. Now How can I pull last 24 updated records from tbl_constit cn or tbl_email by using ‘CHGD_DT’ field?

Change can happen any one of two tables.

SELECT DISTINCT c.constit_id AS constitid,
               REPLACE (c.in_labelname, 'None', '') AS fullname,
               c.firstname AS firstname, c.lastname AS lastname,
               c.indiv_title AS title, e.e_addr AS email,
              'InActive' AS status                               
          FROM tbl_constit cn, tbl_email e,tbl_catcod s
         WHERE c.constit_id = e.constit_id
           AND c.constit_id = s.constit_id(+)
           AND e.e_type = 'EMAIL'
           AND e.e_default = '1'
           AND s.cat_code IN ('SPEMU', 'SPENM')
           AND ((cn.chgd_dt > (SYSDATE - 1)) OR (e.chgd_dt > (SYSDATE - 1)))
      ORDER BY c.constit_id;

This will show all rows where either cn or e was updated in the last 24 hours, if you want to show rows where both where updated, replace the inner OR with an AND.
