I have more than 500 tables in my database.
'insert_date' & update_date column is found in more
than 100 tables with data type as date.
I need a query to list all table names and
'insert_date' column's content.What do you mean by "column's content". A table can have many rows. Do you want to display all the distinct value for these columns?
Below is the query to get the tables which has columns insert_Date and update_date
select table_name
from user_tab_columns
where column_name ='INSERT_DATE'
or column_name ='UPDATE_DATE'
/You can write a PL/SQL block to retrive the distinct values of INSERT_DATE for these tables
declare
TYPE ref_cur IS REF CURSOR;
insert_date_cur ref_cur;
lv_insert_date DATE;
cursor tables_list IS
select table_name
from user_tab_columns
where column_name ='INSERT_DATE';
begin
for cur_tables in tables_list
loop
  OPEN insert_date_cur for 'SELECT DISTINCT insert_date from '||cur_tables.table_name;
  DBMS_OUTPUT.PUT_LINE(cur_tables.table_name);
  DBMS_OUTPUT.PUT_LINE('--------------------------------');
  LOOP
  FETCH insert_date_cur into lv_insert_date;
  EXIT WHEN insert_date_cur%NOTFOUND;
  DBMS_OUTPUT.PUT_LINE(lv_insert_date);
  END LOOP;
CLOSE insert_date_cur;
end loop;
end;I haven't tested this code. There might be some errors. Just posted something to start with for you.
