CREATE FUNCTION error “This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA”

Question

Our database has a function to generate an order number. It reads a value from a Settings table, increments it, then returns the new value. For example:

CREA         


        

Answer 1

There are two ways to fix this:

Execute the following in the MySQL console:

SET GLOBAL log_bin_trust_function_creators = 1;

Add the following to the mysql.ini configuration file:

log_bin_trust_function_creators = 1

The setting relaxes the checking for non-deterministic functions. Non-deterministic functions are functions that modify data (i.e. have update, insert or delete statement(s)). For more info, see here.

Please note, if binary logging is NOT enabled, this setting does not apply.
