![]() ![]() The SQLite Amalgamation is a single file containing all of SQLite proper as well as about half a dozen loadable extensions that are maintained by the SQLite team. It looks like the DLL is sourced from the SQLite Amalgamation. But we also find sqlite3_json_init which is the entry point of the JSON1 loadable extension. In the above snippet, we find functions that are part of the core SQLite code such as sqlite3_initialize and sqlite3_load_extension. ![]() This package has a much larger size (3.72 MB vs 11.44 KB for the wrapper) and is actually what contains the code.ĭownloading and extracting this package, you'll find a lib/ folder with the C# DLL as well as the runtimes/ folder with platform specific native code as mentioned above. For instance, the package .Core.NetStandard is referenced for. It conditionally references various other packages based on the version of. If you open up .nuspec in a text editor you will find that it's a simple wrapper for other packages. The NuGet package contains the native SQLite code compiled to different platforms.Īctually, if you directly download from NuGet and extract it (.nupkg files are just archives), there isn't a lot of code. Since the C code is native, it's specific to different operating systems and architectures. The NuGet package allows us to interface with it by calling the C functions through C#. I started looking into how the NuGet package and SQLite work in hopes of uncovering something that resolves the issue. Structure of the NuGet package and SQLite Unfortunately I wasn't able to find a lot of information on the net to help with this issue. After referencing the necessary packages, the first step was to create a connection to the database.Įnter fullscreen mode Exit fullscreen mode I was working on a Linux Mint machine with. However there were some unexpected challenges and thus began my journey into getting a SQLite extension to load in a. This instance of SQLite doesn't have JSON support enabled by default but I should be able to load the extension as mentioned above. NET, there is the NuGet package, the official database and ADO.NET provider. Instead, you can leverage an existing SQLite instance and load the necessary extensions at run time. The latter is very beneficial because it means you don't have to re-compile your own version of SQLite to include an extension and ship it with your application. Things like JSON support ( JSON1) and full-text search ( FTS3 and FTS4) are implemented in this way.Īlthough loadable extensions can be statically linked at compile time, they can also be dynamically linked at run time. This is a very powerful feature allowing anyone to customize SQLite to their needs. Although SQLite doesn't have built-in functionality for working with JSON, it allows the use of extensions. Some of the data would be stored using JSON. I wanted to use SQLite because it's great as an application file format. NET Core application and was getting to the stage where data needed to be persisted.
