Hello, I took another look also at the implementation of the macro “sql_insert_helper”. https://github.com/error27/smatch/blob/721ca29e1f857b9bda9d55dda989e0fb1c72e590/smatch.h#L1099 I got the impression then that such data processing can benefit more from the usage of prepared SQL statements. https://sqlite.org/c3ref/stmt.html How do you think to adjust any design aspects accordingly?
