SQLite Extension Loading Failure Due to Entry Point Mismatch When attempting to load a custom SQLite extension on Windows, a common issue arises where the sqlite3_load_extension function fails with the error message: "The specified procedure cannot be found." This error typically occurs when the entry point function in the dynamically linked library (DLL) does not…
SQLite DLL Version Discrepancy on Windows 10 When working with the built-in SQLite DLL (winsqlite3.dll) on Windows 10, users may encounter a version discrepancy that raises questions about compatibility and functionality. The DLL provided by Windows 10 is labeled as version 3.23.2, which does not correspond to any official release listed on the SQLite website….
In-Memory Shared Database Creation Fails with Mono.Data.Sqlite Creating an in-memory shared database using Mono.Data.Sqlite can be a challenging task, especially when the database is unexpectedly created on the local hard drive instead of in memory. This issue often arises due to misconfigurations in the connection string or underlying library settings. The primary goal is to…
Compiling SQLite Zipfile Extension with Zlib Dependency on Windows The process of compiling the SQLite Zipfile extension, which relies on the Zlib library, can be challenging, especially on Windows. The Zipfile extension is a powerful tool that allows SQLite to interact with ZIP archives directly, enabling operations such as reading and writing files within a…
SQLite Multi-Statement Parsing and the Need for Precise Statement Separation SQLite is a lightweight, serverless database engine that is widely used in embedded systems, mobile applications, and small-scale web applications. One of its strengths is its simplicity and ease of use, particularly when executing SQL queries. However, when dealing with multi-statement SQL queries, developers often…
Database Corruption Due to File Transfer Mismatch The issue at hand revolves around a SQLite database file that becomes malformed after being transferred from one environment to another. Specifically, the database file is created and populated in a Windows environment using SQLiteStudio and an ASP.NET MVC application. The file is then downloaded to a Xamarin…
UTF-8 Encoding and SQLite’s Internal Handling UTF-8 is a variable-width character encoding that uses one to four bytes to represent Unicode characters. In SQLite, UTF-8 strings are manipulated extensively, especially when binding text to prepared statements or retrieving text from query results. The SQLite API uses char* for input parameters (e.g., sqlite3_bind_text) and unsigned char*…
Time String Parsing Limitations in SQLite SQLite, while powerful and versatile, has inherent limitations when it comes to parsing time strings that do not conform to the ISO-8601 standard. The built-in date and time functions, such as datetime(), date(), and strftime(), are designed to handle ISO-8601 formatted strings efficiently. However, real-world applications often encounter time…
SQLite Shell Command Parsing and Execution Quirks The SQLite shell (sqlite3) is a powerful command-line tool for interacting with SQLite databases. However, its behavior when processing commands like .quit and .exit can be unintuitive, especially when used with the -cmd option. This quirk often leads to confusion, particularly in scripting scenarios where precise control over…
Rounding Discrepancies Between SQLite Versions 3.28 and 3.29 The rounding behavior of the round() function in SQLite has exhibited noticeable changes between versions 3.28 and 3.29, particularly when dealing with floating-point numbers. Users have reported that the results of rounding operations, such as round(1.15, 1) and round(9.95, 1), differ between these versions. In SQLite 3.28,…
