SQLite overview

SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.

The code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private. SQLite is currently found in more applications than we can count, including several high-profile projects. SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file.

The database file format is cross-platform - you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures. These features make SQLite a popular choice as an Application File Format. Think of SQLite not as a replacement for Oracle but as a replacement for fopen() If you need a GUI for database management, you can install NAVICAT. SQLite is a compact library. With all features enabled, the library size can be less than 300KiB, depending on compiler optimization settings. (Some compiler optimizations such as aggressive function inlining and loop unrolling can cause the object code to be much larger.) If optional features are omitted, the size of the SQLite library can be reduced below 180KiB.

SQLite can also be made to run in minimal stack space (4KiB) and very little heap (100KiB), making SQLite a popular database engine choice on memory constrained gadgets such as cellphones, PDAs, and MP3 players. There is a tradeoff between memory usage and speed. SQLite generally runs faster the more memory you give it. Nevertheless, performance is usually quite good even in low-memory environments.

What’s new in version 3.45.1

Updated on Jan 31 2024

  • Restore the JSON BLOB input bug, and promise to support the anomaly in subsequent releases, for backward compatibility.
  • Fix the PRAGMA integrity_check command so that it works on read-only databases that contain FTS3 and FTS5 tables. This resolves an issue introduced in version 3.44.0 but was undiscovered until after the 3.45.0 release.
  • Fix issues associated with processing corrupt JSONB inputs:
    • Prevent exponential runtime when converting a corrupt JSONB into text.
    • Fix a possible read of one byte past the end of the JSONB blob when converting a corrupt JSONB into text.
    • Enhanced testing using jfuzz to prevent any future JSONB problems such as the above.
  • Fix a long-standing bug in which a read of a few bytes past the end of a memory-mapped segment might occur when accessing a craftily corrupted database using memory-mapped database.
  • Fix a long-standing bug in which a NULL pointer dereference might occur in the bytecode engine due to incorrect bytecode being generated for a class of SQL statements that are deliberately designed to stress the query planner but which are otherwise pointless.

WARNING! SQLite v3.25 and earlier have a critical vulnerability. UPDATE to v3.26+ IMMEDIATELY! v3.26 is the current version. More here:

"Cybersecurity researchers have discovered a critical vulnerability in widely used SQLite database software that exposes billions of deployments to hackers.

Dubbed as 'Magellan' by Tencent's Blade security team, the newly discovered SQLite flaw could allow remote attackers to execute arbitrary or malicious code on affected devices, leak program memory or crash applications...."

FYI, this listing now points to the official source at sqlite.org, and no longer has anything to do with Michael Tsai.

This is *not* an official version and thus shouldn't be taking the SQLite name. The author further doesn't provide their project so we can check that the build is unmodified. Use at your own risk.
