I use INavigor system for ad-hoc data extraction from the DB2 database. Only issue is that when it comes to automation. Is there a way I could automate the SQL code to be run on a specific time? I know there is Advance Job Sheduler but I'm not sure how the SQL can be added to the Sheduler. Any one who can help?
IBM added a Run SQL Statements (RUNSQL) CL command at v7.1.
Prior to that, you could store SQL statements in source files and run them with the Run SQL Statements (RUNSQLSTM) command.
Neither of the above allow an SQL Select to be run by itself. For data extraction, you'd want INSERT INTO tbl (SELECT <...> FROM <...>)
For reporting SELECTs, your best bet is to create a Query Manager query (*QMQRY object) and form (*QMFORM object) via Start DB2 UDB Query Manager (STRQM); which can then be run by the Start Query Management Query (STRQMQRY) command. Query Manager (QM) is SQL based, unlike the older Query/400 product. QM manual is here
One last option, is the db2 utility available via QShell.
Don't waste effort creating a day late going out of business because the job scheduler hasn't updated the file system.
Real businesses need real time data.
Just make a SQL view on the iseries that pulls the info you need together.
Query the view externally in real time. Even if you need last 30 days or last month or year to date. These are all simple views to create.

I have for years used MS Access and its query tool that is used for making queries. This tool is so good that I have never been forced to do very much SQL programming myself. The query tool has done all the work.
However, now I have started using Postgres and the Graphical Query Builder in pgAdmin. It seems that the Graphical Query Builder is rather primitive: It cannot be used if you need an aggregate function like SUM or COUNT.
Is this really correct?
Does anybody know a better graphical query builder for PostgreSQL?
Until now I have 'solved' the problem by linking MS Access to the Postgres database through ODBC and used MS Access' query tool to generate SQL commands which I then copy into pgAdmin's Graphical Query Builder - and edit the SQL commands until everything is correct.
SQL Maestro has a query designer, although it is PC only, AFAIK

EMS SQL Manager also has a query designer

Try SQLeo, its free and has a specific feature (autosavepoint) to prevent
ERROR: current transaction is aborted, commands ignored until end of transaction block.
Try a browser-based query builder for PostgreSQL called Skyvia. And you don’t have to worry about which operating system it works. It works where a browser exists. Simply make a connection to your PostgreSQL database and start building your queries. See a sample below.
Note that you can still switch between SQL code and query builder if you want to, just like in MS Access. Get the details here.
I have some codes in SQL developer in which we are pulling data from oracle server and then we are doing too many updation and calculation using sub-queries. In some sub-queries we used join also. Finally we have a single block of codes with multiple sub-queries inside it. Now we need to run this code every month to update data for our new created table, so we want to automated this process and i don't know how to automate these codes in SQL developer
Similar to SQL script to create insert script, I need to generate a list of INSERT from a table to load onto another database (sqlite), like the dump command. I do this for sync purposes.
I have limitations because this will run on a cloud server without acces to the filesystem, so I need to do this in the DB (I can do this in the app server, I'm asking if is possible to do this in the DB directly).
In the app server, I load a datatable, walk his fieldnames and datatypes and build a insert... I wonder if exist a way to do the same in the DB...
I am not entirely sure whether that helps, but you can use simple ETL tool like 'Pentaho Kettle'. I used it once for a similar function and it did not take me more than 10 min. You can also schedule the jobs. I am not sure whether it is supported in database level.

The problem is like this: my company has a service that cannot stop running for long periods of time and I was working on some modifications in the database structure used by this service.
Now that all my modifications are ready and well tested in a test bench environment, I want to export them to the running system. I could do this manually with IBExpert or FlameRobin, but I wanted to know if there is a more automated method for doing this (I feel dumb by spending a whole day creating tables, attributes, and so on one by one).
Is there?
You mention IBExpert - It has the Database Comparer Tool which generates desired DDL to merge databases structure.
And as you know you can use IBEBlock to fully automate that process.
PS. Or deploy your own app using IBEScript.dll - which lets you use all functionalities of the IBEBlock scripting language
Please read: http://ibexpert.net/ibe/index.php?n=Main.IBEScriptDll
Check out the database compare feature of Database Workbench (Windows client). It can compare whatever database objects you select and generate DDL to modify your destination database. Unfortunately you will need the Pro edition, but there is a 30 day trial.
I want to transfer some tables of DB2 to oracle daily for accessing them from web page,
But I don't know commands of DB2. How to do this?
I want this action should perform on database daily on particular time, so is there any tool is available to do this operation. And for writing the program for operating above query which programming language should I use? I am using windows XP.
I think Change Data Capture is used to replicate DML from one database to other databases continuously.
However, what you need is to transfer some data at a particular time each day, thus CDC could be too heavy for that.
You could do a simply "db2 export", and then you could import the generated file from Oracle.
There should be an option to create an adapter in Oracle that permits to query DB2 tables. The opposite is called federation in DB2 (InfoSphere Information Server) that permits to query Oracle tables.

In 11.2 releases, Change Data Capture (CDC) can be done by code template mapping. This allows users to capture the data changes from heterogeneous data source, and load into the target across different platforms.
