ArsTechnica article title Why is SQLite so beautiful?
article The first time Ars TechnIC reader Dan Wiegert visited his local store, he was surprised to see that he could browse through their catalog and buy a variety of products with a single click.
“That was a revelation,” he says.
“You can get products from all sorts of stores.”
Today, he’s using SQLite to manage all of his business’ IT needs.
“I use it as a sort of backup and restore mechanism,” he adds.
“When I need to update a piece of software, I can just import the database into SQLite, and I can save it to a file in the database.”
The first thing you’ll notice when you open up a database is the number of fields.
SQLite’s built-in database table, called a table, contains an array of fields called rows.
Each row has an ID.
For example, you might have a table called Products that has three columns: Name, Price, and Quantity.
The name field has a number and a string value, which Ars Technics reader Adam Wiegley calls “name,” and the price field has two numbers, a price and a quantity.
The second column in the table, Quantity, has a single string value called “Quantity.”
Wiegly says that in his previous store, customers could simply open up the store and look at the product catalog and find out what the item was, but now the database table has a lot more information.
He says that the database’s internal structure is more complex than a traditional spreadsheet.
“It has multiple columns that can be nested, you can have more than one table per column,” he explains.
“Each table has its own table table, its own unique identifier, and so on.”
If you’re familiar with SQLite or similar databases, you’ll know that there’s a very specific way of reading and writing SQL.
“For a lot of things, you have a way of making it easy for programmers to use SQL and then making it hard for programmers not to,” Wiegbes explains.
In addition to making the database simple, SQLite allows for a lot fewer restrictions.
“If you write a query to insert into a table or to update the table and you want to change the data in the data set, that can easily be done with SQL,” Wiggles adds.
In fact, if you want the database to have more restrictions, SQL is built with the ability to do so.
For instance, if a table contains fields that have a value called the column index, and the database has a column called value, then you can change that column index by using an SQL statement.
Wiegbes explains that when you insert a query into the database, SQL will look at that field and look for a SQL statement that has that index value.
If it finds one, then the query will be executed.
If there’s no such statement, then it won’t be executed and the query won’t take place.
“So, you basically have the ability for a developer to say, ‘Hey, I’ve got an index value, and if I want to do this query, I’ll use that value, because I have the index,’ but you have to have the permission to do that,” he continues.
Wigbes adds that you can also have the database set up to be able to handle other kinds of operations.
“And there’s lots of other things that SQL can do, like you can do SQL injections, you could even use SQL injection in an SQL query, to do something,” he points out.
“In fact, you really do have a lot in terms of the ability of a developer who has a little bit of knowledge of SQL to do things that are not possible with a traditional database.”
For instance: if you’re going to do a transaction with an SQL operation, you don’t need to know anything about SQL or the database.
Wigs says that, even if the database is simple, it still can’t be a “real” database.
“The SQL database can’t handle anything that you do with a relational database,” he tells Ars.
“This is a database, but the database doesn’t have a relational schema.”
And even if you do have an SQL database, you still can only access data within that database.
That’s because the database needs to know about other databases that exist in the same system.
For those other databases, there are “table references,” which are just strings that can represent database tables.
The database has to know where to look to find tables and columns, and these tables and fields can
