What does “i_am_a_dummy flag” do in MySQL?

The “i_am_a_dummy flag” enables the MySQL engine to refuse any UPDATE or DELETE statement to execute if the WHERE clause is not present. Hence it can save the programmer from deleting the entire table my mistake if he does not use WHERE clause.

The “i_am_a_dummy” flag in MySQL is a compilation flag used during MySQL source code compilation. When enabled, it allows certain sections of code to be compiled with less optimization. This flag is primarily used for debugging purposes or for testing scenarios where performance optimizations are not desired. It doesn’t have any direct impact on the functionality of MySQL in typical usage scenarios.
