Hello, starting from some software database spesification, defined in some Enhanced entity relationship diagram,
resulting in all kinds of relationships, 1:1 1:Many Many:1 Many : many And last but not least: Subclass/superclass relationship This seems to be a small problem for me, With the current version of MySQL. How can I use joins to code in SQL syntax an arbitrary model of An Entity relationship diagram ? With all constraints correctly implemented, Without any foreign keys ? Without any "on delete set default", I hope this can be implemented also without Combining MySQL to PHP, Perl or C.
