The application file is portable in all operating systems.Ĭontent can be updated continuously so that little or no work is lost in a power failure. Performance problems can often be resolved, even later in the development cycle, using CREATE INDEX which helps to avoid costly redesign, rewrite, and retest efforts. The file format can simply be extended in future releases by adding new tables or columns. There is no application file I/O code to write and debug.Ĭontent can be accessed and updated using concise SQL queries instead of lengthy procedural routines. Making small edits overwrite only the parts of the file that change, reducing write time and wear on SSD drives. The application loads only the data it needs, rather than reading the entire file and holding a complete parse in memory. Reading and writing from an SQLite database is faster than reading and writing files directly from disk. There are many advantages of using SQLite as an application file format: In contrast to most other database management systems, SQLite is not a client-server database engine but is embedded into the end program. SQLite is a relational database management system (RDBMS) that is contained in a C library. Below are the topics covered in this blog: In this blog on “SQLite Browser”, we will learn everything you need to know about this browser. It is for developers wanting to create databases, search, and edit data. In the next chapters we will start using SQLModel to interact with the database, and we will continue to use DB Browser for SQLite at the same time to look at the database underneath.DB Browser for SQLite is a high quality, open-source tool to design, create, and edit database files compatible with SQLite. This will be useful to verify the data in the database is looking correclty, to debug, etc. We also saw how to use it to write some SQL directly to the SQLite database. We saw how to interact with SQLite databases in files using DB Browser for SQLite in a visual user interface. Of course, you can also go and take a full SQL course or read a book about SQL, but you don't need more than what I'll explain here on the tutorial to start being productive with SQLModel. And you don't have to be a SQL expert to use SQLModel.īut if you are curious and want to get a quick overview of SQL, I recommend the visual documentation from SQLite, on SQL As Understood By SQLite. I will keep showing you small bits of SQL through this tutorial. You will see the "execution finished successfully" message.Īnd if you go back to the Database Structure tab, you will see that you effectively created again the same table. Write the same SQL that was generated in the previous step:ĬREATE TABLE "hero" ( "id" INTEGER, "name" TEXT NOT NULL, "secret_name" TEXT NOT NULL, "age" INTEGER, PRIMARY KEY ( "id" ) ) This time, if you see the dialog to create a new table, just close it by clicking the Cancel button. database.db file in your project directory. Now, to see how is it that SQL works, let's create the table again, but with SQL.Īnd delete that. You will see again the same table we created. Now click on Open Database to open the database again, and select the same file. Confirm the Table ¶įirst click the button Close Database to close the database. The only step left is to click Write Changes to save the changes to the file.Īfter that, the new table is saved in this database on the file. Now you will see that it shows up in the list of Tables with the columns we specified. There could be more SQL statements in the same SQL string. It also has the semicolon " " that marks the end of the SQL statement.
