![]() ![]() The first command will create the alias sqlite3 that you can use to open a database. Exit the sqlite> prompt by typing in Ctrl C, and in the same git-bash terminal without changing folders, run these commands:Įcho "alias sqlite3=\"winpty $/sqlite3.exe\"" > ~/.bashrc We want to be able to access this command quickly from elsewhere, so we’re going to create an alias to the command. ![]() If that command opens a sqlite> prompt, congratulations! You’ve installed SQLite. Try running sqlite with the command winpty.From your git-bash terminal, open the directory of the unzipped folder with cd ~/Downloads/sqlite-tools-win3100/sqlite-tools-win3100/.Download the sqlite-tools-win3100.zip file and unzip it.For example, if the name of the file you download is sqlite-tools-win3200.zip, you would change 3200100 in each command below to 3390200. You should download whichever version is listed on the SQLite Download page, and replace 3200100 in the instructions below with the version number you downloaded. Our instructions use the version number 3200100. The last number in each file name is the current SQLite version. This page has versions of SQLite for Windows, Mac OS X, and Linux. ![]() Setting Up SQLiteīinaries for SQLite can be installed at the SQLite Download page. SQLite’s maintainers consider it to be among the most replicated pieces of software in the world. SQLite is used worldwide for testing, development, and in any other scenario where it makes sense for the database to be on the same disk as the application code. Uses for SQLiteĮven considering the drawbacks, the benefits of being able to access and manipulate a database without involving a server application are huge. Storing different data types in the same column is a bad habit that can lead to errors that are difficult to fix, so it’s important to be strict about your schema even though SQLite will not enforce it. We could accidentally insert the wrong data types in the columns. However, SQLite will not reject values of the wrong type. The example below shows that the id column expects to store integers, the name column expects to store text, and the age column expects to store integers: ![]() SQLite creates schemas, which constrain the type of data in each column, but it does not enforce them. Where many other database software would reject data that does not conform to a table’s schema, SQLite allows users to store data of any type into any column. Lastly, SQLite does not validate data types. Furthermore, SQLite does not offer the same exact functionality as many other database systems, limiting some advanced features other relational database systems offer. It also may require some more work to ensure the security of private data due to the same features that make SQLite accessible. SQLite’s signature portability unfortunately makes it a poor choice when many different users are updating the table at the same time (to maintain integrity of data, only one user can write to the file at a time). This fact allows for a great deal of accessibility: copying a database is no more complicated than copying the file that stores the data, sharing a database can mean sending an email attachment. In SQLite, a database is stored in a single file - a trait that distinguishes it from other database engines. It is software that allows users to interact with a relational database. We will describe what it does, its main uses, and then explain how to set it up and use it on your own computer. In this article, we will be exploring the extremely prevalent database engine called SQLite. ![]()
