<function name="QueryTyped" parent="sql" type="libraryfunc"> <description> Performs a query on the local SQLite database with proper type handling and parameter binding, returns a table as result set, empty table if no results, and false on error. Unlike <page>sql.Query</page>, this function properly handles SQLite data types and allows safe parameter binding to prevent SQL injection attacks. <warning> * Always use parameter binding with `?` placeholders instead of string concatenation to prevent SQL injection vulnerabilities. This function requires the exact number of parameters to match the number of placeholders. * Always use parameter binding with `?` placeholders instead of string concatenation to prevent SQL injection vulnerabilities. * This function requires the exact number of parameters to match the number of placeholders.⤶ * This function only executes a single SQL statement, unlike <page>sql.Query</page> which can execute multiple statements separated by semicolons. * Large INTEGER values (beyond ±9,007,199,254,740,991) are returned as strings to preserve exact values. This is because Lua represents all numbers as doubles, which lose precision for integers larger than 2⁵³-1. Returning them as strings prevents data corruption from rounding errors. </warning> </description> <added>2025.05.29</added> <realm>Shared and Menu</realm> <args> <arg name="query" type="string">The query to execute with optional `?` parameter placeholders.</arg> <arg name="..." type="vararg">Parameters to bind to the query placeholders.
