I ran a few queries in SQL Developer and closed the query result panel after i looked through the data. I have then deleted the data but now im trying to see if I can find/view the data i viewed somehow?
is there a way to find the data i viewed?
No, as far as I know, SQL Developer has no feature that saves results of previous queries.
Once you close them, they are 'gone.'
But, you can setup SQLDev not to close the results as you execute new queries. Benefit, you have to explicitly close the panel before you 'lose' the results.
Warning: Close these tabs as you can. They tie up potentially both CLIENT and SERVER side resources.

it's been 2 months I'm working for a new client on BI Reporting on Oracle BI Publisher within an OracleCloud CRM and HCM. to make query to OracleCloud database I have to use notepad++ and then copy/past my query in the Query textArea on BIPublisher (which is a simple text area without any syntaxe check or color), I was wondering if there are some experts who might know a way to connect SQL Developer to OracleCloud database so I can run my queries directly without copy/past on the browser.
thank you a lot
There's no direct access to the underlying Oracle Database from your SaaS subscription.
We (the SQL Developer team) are working with a few of the SaaS business owners to make SQL Developer Web available for their subscribers. This would allow you to run queries directly against your database w/o having to do the copy/paste jump you're doing today in BI Publisher.
I cannot provide guidance on when this will happen or even if your particular services will make it available.
The TL;DR answer to your question is 'No, but we are working on it'
I am new to JasperReports, I need a few heads up before going forward with my development. My colleagues told me they are able to generate a basic report, but they are stuck with what approach should be used.
I was told we could:
write the queries in each report
run the queries outside the report, and pass it to the report as a
datasource
Which approach is preferable? Does passing the datasource have any performance hits compared to passing the bean? Also would like to know does first approach run in a different jvm?
Current Project Architecture
Struts 2 - Spring 2.5 - Spring JDBC
If you and your team are just starting out with JasperReports I would recommend embedding the SQL query into each report. It makes building the reports in iReport much easier, since you can constantly preview your report with live data while working on it.
As far as performance, I do not think it really is not going to matter in the most basic of examples. If it is just a SQL query then no matter what scenario you use it is going to be using JDBC with the connection you give it. So I would ignore performance for now.
With that said, if you already have the data (i.e you have displayed on a screen and you want to allow the users to then export it to PDF or whatever), you could simply pass it in as a datasource and not take the performance hit of running the query again.
Another scenario you may want to use your own datasource is if you wanted to manipulate the data before it was exported in the report. Maybe some crazy sort that you could not pull off in SQL or something.
As far as your last question, it should all run in the same JVM (at least from my understanding).
I'm learning a new product of my company and the database is huge.
What I'm doing is to learn feature by feature and through that to understand the codes and the associated database's data/functions/ect.
What I need: To see the change-set made to the database/data-rows recently, e.g. after I create a new user account, I want to see what are the new rows updated/created after I do that.
Is it possible? Please share if it is. Thank you!

I would set up a trace with the SQL Server Profiler. In the trace you can see what the client does when you create a new user.
I have been working with Microsoft SQL Server since 6.5 along with other database like Oracle, MySQL and SQLite. I equally appreciate or hate all these DBMS for some point or the other.
On our forthcoming project, we are considering Postgres in the back-end. I have already started playing with it, pretty interesting for me.
I have always heard good comments on Postgres database, but I don't like the admin studio at all. While creating new a table, I hate the way of creating columns on pgAdmin by having to click add button again and again.
Are there any "Studios" for Postgres database that provide
more organized table creation process (spreadsheet like)
graphical view designer
What's wrong with plain SQL? Writing plain SQL goes much faster than click-wait-click-wait-type-click-wait-ok-wait. You could use any tool for this, pgAdmin as well.
Open Office Base can also connect with PostgreSQL, works like MS Access. And talking about MS Access, MS Access can also connect to PostgreSQL to create tables, views, etc.
See this official list of Administration/Development tools.
EMS SQL Manager seems to be a good option.
for the graphical view of SQL queries
maybe SQLeo can Help
I have an app the runs at the store level extracting data out of a POS system. This app asks the POS system for data which in return produces some .DBF files. The app loads the DBFs in memory and saves it to SQL Server 2008 Express at the store level. This happens at 3 different stores.
I have been looking into the Microsoft Sync Framework, but have not come across any good examples of how to sync tables in one direction only, from each of the stores into a single database at the corporate level.
The data at each one of the stores is being managed by the app(delete, update, insert).
Does anyone know a good article, that I could read about synchronizing SQL data?
Thank you.
