In relation to Teradata Client 14.10, I was wondering if I could use this tool to run SQL, view tables and change passwords?
New to teradata.
Many Thanks.
Use the SQL Assistant from the client set, it would suffice.
Studio is too cranky at this point, was supposed to be an equivalent eventually replacing the assistant.
... teradata studio; a pre-baked eclipse plugin. Works pretty well and doesn't require all the old men ODBC configuration '90s msft weirdness. sorry a 'lil high rugh now.

Will changing to Oracle from SQL Server require changing any of the existing LINQ or Entity Framework development of a .NET application? The project is currently using SQL Server but there is a recommendation (not a requirement) to use Oracle.
An ORM is a layer to abstract you away from the database. Ideally you won't know what the underlying DB is.
I would get an evaluation copy of Oracle and point your EF at it. The EF is very good at communicating with DBs and I doubt you will have any problem.
Practically you may run into different issues; but until you do some research and ask specific questions about issues this community will be of no help. If you have a data engineer leave it to them to decide on the DBMS and you choose a robust ORM (EF) to abstract you.

I just wondered and start reading SQLite source code.
There weren't any fopen,fclose except logging functions.
I tried to track down sqlite3_open, sqlite3_prepare, I came into sqlite3parse and stuck.
There is fopen in
sqlite3MemdebugDump
sqlite3Memsys3Dump
sqlite3Memsys5Dump
sqlite3VdbeTransferError
which are debug functions.
Are they wrote their own disk handler?
(I always stunned how professional applications handle this kind of things.)
Summary: How SQLite handle files without fopen?
SQLite accesses files through its OS interface, which is implemented in the os_*.c files.

Recently I've got some problems in my live site but the localhost version is fine. But live site contains some updated articles of type page/story and also comments.
So what I want to do is to move node & comment table to localhost. I'm not using comments in any custom modules.
Will moving comments & node can have any issues given some minor db settings may be different between localhost and live site versions?
Just dump the entire database. Unless you're using a module like domain access or sso you should be able to just take the entire database without it causing issues. You might want to clear the cache tables first though.

Has anyone connected the R package to QuickBooks? I know there is an ODBC driver than can be bought. Just wondering if anyone has already gone down this road.
Any insight will be much appreciated!

Google QODBC. It allows you to access Quickbooks via ODBC.
However, it works through creating an interface to XML files. For large QB files it can be painfully slow if you don't properly use indices and limit the data to exactly what is necessary. It's also very quirky. Lastly, not all tables are exposed (Quickbooks fault, not theirs) such as some payroll tables.
What I often ended up doing for large QB files is exporting the data at night via the QODBC driver into a sql database so that ad hoc analysis could be run quickly without compromising the performance for QB users during the day.
Good luck!
