Virtual Tables Virtual Tables In SQLite A virtual table is an object that is registered with an open SQLite database connection. From the perspective of an SQL statement, the virtual table object looks like any other table or view. But behind the scenes, queries from and updates to a virtual table invoke callback methods on the virtual table object instead of reading and writing to the database file. The virtual table mechanism allows an application to publish interfaces that are accessible from SQL statements as if they were tables. SQL statements can in general do almost anything to a virtual table that they can do to a real table. You cannot create a trigger on a virtual table You cannot create additional indices on a virtual table. Particular virtual table implementations might impose additional constraints. A virtual table might represent an in-memory data structures. Here are some postulated uses for virtual tables: Access to SQLite's internal symbol table information. Usage Implementation
How to create a MySQL Workbench connection to Amazon EC2 server | Lotus Domino | Symetrik Design I’ve been working with Amazon Web Services (AWS) Elastic Cloud Computing (EC2) quite a bit recently. I’ve also started working with Ubuntu at the same time. The result is the ability to quickly spin up new instances of Ubuntu server to use for various reasons without all the hassle of new hardware, or even alot of configuration headache. Using Amazon Machine Images (AMIs), an administrator can spin up an instance that is already configured, patched, and ready to run. Using this technique and technology that is new to me has created a bit of a learning curve, and one thing that caught me off guard was the need to use keypairs instead of username/password to access the servers, which is more secure, and is the default method for accessing AWS EC2 servers. I was able to easily figure out how to access an AWS EC2 using a keypair with SSH command line, and Filezilla, but MySQL Workbench seemed a little more complex. Above you can see the diagram, which shows my new connection dialogue screen.
