Issue Overview: Floating-Point Precision Discrepancies in SQLite Output Modes The core issue revolves around the inconsistent handling of floating-point numbers in SQLite’s output modes, particularly .mode quote and .mode insert. When a floating-point number such as 13.0 is queried, the output in .mode quote displays as 12.999999999999999999, which is unexpected and incorrect. This behavior is…
Issue Overview: JSON Subtype Not Respected in .mode json Output When using SQLite’s .mode json to format query results as JSON, the JSON subtype of values is not respected in the output. This issue arises when functions like json_array() or json_object() are used to generate JSON values. Instead of embedding the JSON value directly into…
Issue Overview: .schema Command Modifies CREATE TABLE Statements with "IF NOT EXISTS" The .schema command in the SQLite command-line interface (CLI) is designed to output the SQL statements required to recreate the schema of a database or a specific table. However, users have observed that the .schema command unexpectedly modifies CREATE TABLE statements by adding…
Understanding the CSV Output Rendering Problem with RTL Text in SQLite The issue at hand revolves around the rendering of Right-to-Left (RTL) text, specifically Hebrew, within CSV output generated by SQLite. When executing a SELECT query and exporting the results to a CSV file, the RTL text is enclosed in double quotes, which is standard…
Understanding the SQLITE_SCHEMA Table Reference Mismatch in C Applications Root Cause Analysis: Version-Dependent Schema Table Aliases The core issue arises from the use of SQLITE_SCHEMA as a table name in a C application linked against an older SQLite library version. SQLite historically used sqlite_master as the internal schema table, with SQLITE_SCHEMA introduced as a case-insensitive…
Metadata Absence in sqlite_schema Despite Successful Table Creation Issue Overview When working with SQLite databases via a JDBC client, users may encounter a scenario where tables are created successfully (e.g., using CREATE TABLE IF NOT EXISTS syntax), but the associated metadata does not appear in the sqlite_schema or sqlite_master system tables. This issue manifests as…
Issue Overview: Combining Decimal Precision, Thousand Separators & Negative Parentheses in SQLite The challenge involves formatting numerical values in SQLite to meet three requirements simultaneously: Display numbers with thousand separators (e.g., 1,234,567) Enforce two decimal places with proper rounding (e.g., 1234567.4567 → 1,234,567.46) Represent negative numbers within round brackets instead of using a minus sign…
Issue Overview: Column Header Truncation in SQLite When Using .explain on When using the SQLite command-line interface (CLI), users may encounter an unexpected behavior where column headers are truncated when the .explain on command is enabled. This behavior is particularly noticeable on Windows 11 but may occur on other platforms as well. The issue manifests…
Understanding sqlite3.exe Output Modes and Multi-Statement Execution Challenges The SQLite command-line interface (sqlite3.exe) provides several output formatting options through its .mode directive, each designed for specific use cases. Two modes central to this discussion are CSV and ASCII, which exhibit fundamentally different behaviors when processing multi-statement SQL inputs. In CSV mode, rows are delimited by…
Understanding the Nature of the .bak File and Its Compatibility with SQLite The first step in addressing the issue of converting a .bak file to Excel is to understand the nature of the .bak file itself. A .bak file is typically a backup file, and its contents can vary widely depending on the software that…
