I need to send a couple of tables from our Oracle database to one of our developers.
I usually just send the entire database. But how to send only selected tables?
You can use the Export tool from oracle.
exp scott/tiger file=emp.dmp tables=(emp,dept)
Here is a link to the FAQ from oracle.

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.
We have a software solution that involves syncing some data between a Progress database and SQL server. Unfortunately, we do not have any Progress gurus in house, so I'm working kinda blind here and would welcome any advice that is on offer.
For the workflow that is already in place, what would work very well for us is the ability to do an external call to insert a row into an SQL database from an within ABL procedure's 'for each' loop.
Is anyone able to direct me to any code snippets or articles that might help me achieve this?
Many thanks,
In case your SQL database is MS SQL Server, you might want to have a look at OpenEdge DataServer for Microsoft SQL Server (web.progress.com/en/openedge/dataserver-microsoft.html, documentation.progress.com/output/OpenEdge102b/pdfs/dmsql/dmsql.pdf).
The DataServer provides you with ABL access to a non-Progress database so you can use standard Progress statements, e.g. CREATE to add new records or FOR EACH to retrieve query results.
OpenEdge DataServers are also available for Oracle (using Oracle Call Interface), DB2 and Sybase (using ODBC). The DataServer for MS SQL Server uses ODBC behind the scenes as well. web.progress.com/docs/datasheets/openedge/openedge_dataservers.pdf
You dont need the dataserver, connection with ADODB works fine in ABL, you can even call stored-procedures with the command object, the user you connect with will have to be granted EXEC rigths on the SQL-Server to do that.
I'm not a Progress guru, but I did do some work in it for awhile. AFAIK there is no way to have ABL code connect to a non-Progress database (part of that whole vendor lock-in strategy Progress Corp. leverages).
Your best bet is probably to have the ABL code serialize the records to XML, and use something like ActiveMQ (or even a plain socket or named pipe/FIFO depending on your setup) to send them to a program written in a more capable language to do the SQL insert.
In T-SQL (Microsoft SQL 2008), how can I make a new database which will have the same schemas, tables, table columns, indexes, constraints, and foreign keys, but will not contain any data from the original database?
Note: making a full copy, then removing all data is not a solution in my case, since the database is quite big, and such full copy will spend too much time.
See here for instructions: How To Script Out The Whole Database In SQL Server 2005 and SQL Server 2008
In SQL Management Studio, right click on the database and select "Script database as"
http://msdn.microsoft.com/en-us/library/ms178078.aspx
You can then use the script to create an empty one.
Edit : OP did say 2008
I use liquibase for this purpose. Just point liquibase to a different server and it will use your changelog to bring the second database up to date, schema wise. It has the added benefit that the changelog file gets stored in source control and so I can have tagged versions of it, allowing me to restore a database to what a specific version of my app is expecting.
I know ways to script a SQL CE Database, but does anyone know a way to diff two databases and output a script sync one of them to the other (ie generate drops and inserts to make them the same).
I am looking for a way that I can update my hand held applications without having to copy over the existing database. The first step is to be able to make a change script.
Script the two SQL CE databases, and load them into 2 SQL Server Express tables, and use one of the many SQL Server compare tools to compare these.
Are you trying to copy changes in a local SQLS CE database to another local CE database? Or are you trying to replicate changes between multiple CE clients with internet access? If the latter, check out SQLS CE Merge Replication.
I am looking for a tool/command which can compare data between two PostgreSQL databases. The reason to do this is to have some external verification that the SQL script responsible for data migration from one PostgreSQL database to the other have been written correctly.
Any pointers would be appreciated
regards
Sameer
EMS makes a tool which can do this.

The PostgreSQL site has a nice Software catalogue. Peruse the Administration/development tools category.
