Prior to SQLite 3.45.0 the json_valid() function only accepts one argument – the value to check. However, from SQLite 3.45.0 (released on 15 January 2024), we can now provide an optional second argument to define what valid – or “well formed” – means.

Continue readingSQLite has introduced the FORMAT() function, which can be used to format strings.
More precisely, it has actually just renamed its SQL PRINTF() function to FORMAT(). The reason is for better compatibility with other DBMSs. The original PRINTF() name is retained as an alias for backwards compatibility.
The FORMAT() function (or its naming) was introduced in SQLite 3.38.0, which was released on 22 February 2022.
The 10.6.0 release of MariaDB has added a JSON_TABLE() function.

The TO_CHAR() function has beeen introduced in MariaDB 10.6.1.
