Log_bin_trust_function_creators Mysql

We now have our dump file containing the functions and stored procedures.
I thought I was done at this stage. But I got the following error message while restoring the database on the destination server:

ERROR 1419 (HY000) at line 1140: You do not have the SUPER privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)


The error message is pretty clear. Binary logging needs to be enabled in order to restore the functions. There are two ways for doing this:

  • Execute the following command into the MySQL console:
    SET GLOBAL log_bin_trust_function_creators = 1;
  • Add the line log_bin_trust_function_creators = 1 to the mysql.ini configuration file
