I am using SQL developer to run queries on a database and one of the tables shows a create date for each request added. The query pulls a unix time stamp back and I haven't had much luck on Google when searching for Oracle SQL Dev.
select ID, CREATED
from REQUESTS
where ID = 'bob'
order by create_date DESC;

I'm using Talend Open Studio for Data Integration.
I have tables that are generated every day and table names are suffixed by date like so
dailystats20220127
dailystats20220126
dailystats20220125
dailystats20220124
I have two-part question.
I want to look at the table which has yesterday's date in it so sysdate - 1 and I want to fetch data from yesterday
select 'dailystats' ||to_char(sysdate - 1,'YYYYMMDD') TableName
from dual;
How do I retrieve schema for a dynamic name?
How do I pull data from that table.
I've worked with static table names and its a straightforward process.
If the schema is always the same, you just define it once in your input component.
In your input component set the sql as :
"select [fields] from dailystats"+ TalendDate.formatDate("yyyyMMdd", TalendDate.addDate(TalendDate.getCurrentDate(), -1, "dd"))

I am using select TIMESTAMP from dba_tab_modifications query it's giving me last updates in table
but I need last execution of select query statement on a particular table
Thanks in Advance

Oracle does not keep this information by default. You need to enable the appropriate AUDIT rules. But I'd question what problem you think this will solve. Auditing every access to a table will be a lot of audit records.
In my Java program, I am trying to take values from a PostgreSQL database and using this data I am using a Select query with an Oracle database.
Problem is, it is taking too much time to complete this task. First I am fetching data from Postgres table and load into variable.
Then with this variable I am executing a select query against an Oracle table.
But I want to make this process faster. Is it possible to perform this task in one query that takes data from PostgreSQL table and fetch data from Oracle table?
Postgres statement:
select filial_name
into f_name
from branch
where id=1;
Oracle statement:
select sum(credit)
from balance
where filial_n = f_name;
Above process continues in loop.
If you have to run a massive join between an Oracle table and a PostgreSQL table, that is never going to be very fast.
But you can do much better than performing the join in your application by defining an oracle_fdw foreign table in PostgreSQL and performing the join in PostgreSQL.
Im currently using oracle 11g. I had extracted data from the schema once at a specific date to do some cleansing process. Suppose that now i would want to extract again but only with new/updated data from the last date i extracted, is there anyway i could get it? unfortunately these data does not have any column that store last edited date.
i was wondering if Oracle would automatically store that type of info that i could check? perhaps any transaction log?
Thanks,

One way would be to enable flashback and then you can do:
SELECT * FROM table1
MINUS
SELECT * FROM table1 AS OF TIMESTAMP TIMESTAMP '2018-01-01 00:00:00.000';
To get all the rows changed since 2018-01-01.
As part of my project, new columns are introduced in many tables. I wanted to find out the date in which this columns are introduced. Is there a way I can query the date of insertion of all the columns in a specific table in Oracle SQL Developer 3.0.04.
You can try to use the last_ddl_time object from the dba_objects table.
