Read from (SELECT) Database table - SQLite3 with Python 3 part 3
 
11:20
In the previous tutorials, we've covered creating a database and populating one, now we need to learn how to read from the database. Reading from a database is where the power of using something like SQLite over a flat file starts to make sense. While we can query the entire table, we can instead just query a single column, or even based on specific row values. Let's see what I mean sample code and text tutorial: https://pythonprogramming.net/sqlite-part-3-reading-database-python/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

Learn Python: Intro to SQL Queries
 
03:20
Learn all about SQL Queries in Python: https://www.datacamp.com/courses/introduction-to-relational-databases-in-python Introduction to SQL The SQL query language can be used to do anything within the database. It can select data, insert new data, update existing data, and delete it. It can also be used to create, alter and delete tables and columns. The first SQL statement we'll learn is the select statement, which provides the basic method of extracting information from your database. The general syntax of a select statement is select COLUMNS from TABLE CONDITIONS. For Example, we can select the pop2008 column from the people table. We can also select all the columns from the people table with a '*'. Let's execute this last query. We'll begin by importing create_engine and creating an engine. Next, we will establish a connection by using the connect method on the engine. Then we can define our select statement and pass it to the execute method on the connection. This gives us an object we can use to fetch the results, which we assign to the variable results_proxy. Then we tell results_proxy to fetch all the results via the fetchall method. Now results will contain all of our data from the people table. Let's pause for just a moment and look at that object that the execute method gave us. That object is called a ResultProxy and it can be used in a variety of different ways to get the data returned by our query. When we use a fetch method, such as fetchall, on the ResultProxy, we get a ResultSet that contains the actual data we asked for in the query. This separation between the ResultProxy and the ResultSet allows us to fetch as much or as little data as we desire. We'll explore this more in a later section. Let's learn how to work with a ResultSet. In this example we are using the results from the prior query. We'll start by getting the first_row of the results using an index of 0. By printing the first row, we can see the data it contains. If we want to know what columns are in the row, we can find out by using the keys method. Finally, we print the value of the state column from the first row, by using the column name as an attribute on the row object. In the prior query example, we wrote a normal SQL statement as a string; however, manipulating a string to build more complex statements can be very overwhelming. The beauty of SQLAlchemy is that it allows us to assemble these complex statements in a Pythonic way. Pythonic refers to code that adheres to the idioms of Python's common guidelines and express its intent in a highly readable way. SQLAlchemy also hides the difference between database types so we can focus on the data we want to work with instead of the differences we might encounter in each database type. Let's rebuild the same query using SQLAlchemy. The first three steps of creating an engine and establishing a connection will be the same. After that, we will need to initialize our metadata and reflect the table as we did previously. Then in line 7, we build our select statement. Hang tight we'll talk more about this in a second. Finally, we execute the statement and fetch all the results. The SQLAlchemy select statement works the same as a SQL select statement, and in its most basic form takes a list of Column or Table objects. For example, stmt = select([census]) will select all the columns of all the rows in the census table. SQLAlchemy generates the same SQL statement we wrote by hand. We can see that by using the print() function on the statement which outputs SELECT * FROM census. Now it's your turn write several SQL queries, both as raw SQL and in the more Pythonic way using SQLAlchemy. We'll be continuing to use the US Census database. Let's practice.

Creating a database, table, and inserting - SQLite3 with Python 3 part 1
 
10:59
Welcome to an SQLite mini-series! SQLite, as the name suggests, is a lite version of an SQL database. SQLite3 comes as a part of the Python 3 standard library. Databases offer, typically, a superior method of high-volume data input and output over a typical file such as a text file. SQLite is a "light" version that works based on SQL syntax. SQL is a programming language in itself, but is a very popular database language. Many websites use MySQL, for example. SQLite truly shines because it is extremely lightweight. Setting up an SQLite database is nearly instant, there is no server to set up, no users to define, and no permissions to concern yourself with. For this reason, it is often used as a developmental and protyping database, but it can and is used in production. The main issue with SQLite is that it winds up being much like any other flat-file, so high volume input/output, especially with simultaneous queries, can be problematic and slow. You may then ask, what really is the difference between a typical file and sqlite. First, SQLite will let you structure your data as a database, which can easily be queried, so you get that functionality both with adding new content and calling upon it later. Each table would likely need its own file if you were doing plain files, and SQLite is all in one. SQLite is also going to be buffering your data. A flat file will require a full load before you can start querying the full dataset, SQLite files don't work that way. Finally, edits do not require the entire file to be re-saved, it's just that part of the file. This improves performance significantly. Alright great, let's dive into some SQLite. https://pythonprogramming.net/sql-database-python-part-1-inserting-database/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex
