Understanding the Absence of Native Stored Functions and Procedural Logic in SQLite Issue Overview The core issue revolves around the absence of native support for user-defined stored functions and procedures in SQLite, which are commonly available in client-server relational database management systems (RDBMS) like MariaDB, PostgreSQL, or Oracle. Stored functions and procedures allow developers to…

Issue Overview: SQLITE_TRACE_ROW Firing Before SQLITE_TRACE_STMT When using the sqlite3_trace_v2 function in SQLite, developers can register callback functions to trace specific events during the execution of SQL statements. Two of the most commonly traced events are SQLITE_TRACE_STMT and SQLITE_TRACE_ROW. The SQLITE_TRACE_STMT event is expected to fire when a prepared statement begins execution, while the SQLITE_TRACE_ROW…
