Floating-Point Precision and Storage in SQLite Floating-point numbers are a fundamental data type in databases, including SQLite, but they come with inherent precision limitations due to their binary representation. SQLite, like many other systems, uses the IEEE-754 standard for storing floating-point numbers. This standard defines how floating-point numbers are represented in binary, which can lead…
Core Problem: Absence of Built-In JSON Pretty-Printing in SQLite Issue Overview: Storing vs. Human-Readable JSON Presentation SQLite’s JSON1 extension provides robust support for storing, querying, and manipulating JSON data. However, a critical gap exists in its functionality: the inability to convert minified JSON into a human-readable, indented format directly within SQLite. Users who store compact…
Understanding Column Alignment Behavior in SQLite CLI Output The SQLite command-line interface (CLI) provides a columnar output mode (.mode column) that formats query results into aligned columns for improved readability. However, numerical columns (e.g., INTEGER, REAL, BOOLEAN) are left-justified by default, which conflicts with conventional data presentation where numerical values are typically right-aligned. This behavior…
SQLite Integer Storage and C# DataType Mismatch SQLite, as a lightweight and flexible database engine, has a unique approach to data typing. Unlike traditional databases that enforce strict column types, SQLite uses a dynamic type system. This means that any column, except for INTEGER PRIMARY KEY, can store any type of data. However, when it…
Diagnosing Unexpected Line Breaks in SQLite CLI Column Output Understanding the Core Display Anomaly The issue at hand involves unexpected blank lines appearing between rows when querying a specific column (e.g., status) in SQLite’s command-line interface (CLI). These gaps are not present in the underlying data but manifest during result rendering. Key observations include: Blank…
Understanding the Absence of <table> Tags in SQLite’s HTML Mode Output Issue Overview The core problem arises when using SQLite’s .mode html command to generate HTML-formatted query results. While this mode outputs rows and columns wrapped in <TR>, <TD>, and <TH> tags, it intentionally omits the enclosing <table> and </table> tags. When saved to an…
Understanding Box Mode Column Distortion in Unicode Contexts The SQLite command-line shell’s .mode box feature provides visually appealing tabular output with ASCII borders. However, when rendering UTF-8 text containing characters classified as double-width under Unicode standards (e.g., CJK ideographs, emojis, or certain symbols), the column boundaries become misaligned. This occurs because the SQLite shell assumes…
JSON Path Output Format Change in Recent SQLite Versions The behavior of the json_tree() function in SQLite has undergone a subtle but significant change in recent versions, particularly affecting the format of the path column in its output. Specifically, the way object labels are quoted in the path output has been modified. For example, in…
Inconsistent AM/PM Formatting and Missing 12-Hour Clock/ISO Week Support in SQLite’s strftime Function Issue Overview: Conflicting Implementations of %p/%P Modifiers and Absence of Standardized 12-Hour Time/ISO Week Formats The core issue revolves around three interrelated problems with SQLite’s implementation of the strftime function: Case Sensitivity Inconsistencies with %p and %P Modifiers The %p format specifier…
Understanding SQLite HTML Output Mode and Its Limitations SQLite’s HTML output mode is a convenient feature that allows users to export query results directly into an HTML table format. This mode is particularly useful for generating quick HTML representations of database tables or views without requiring additional tools or scripts. However, the simplicity of this…
