Fremmednøgler ?????
Har fremmednøgler i MySQL ingen betydning, sådan tolker jeg ihvertfald nedenstående uddrag fra MySQL Reference Manual for version 4.0.5-beta.The FOREIGN KEY, CHECK, and REFERENCES clauses don't actually do anything, except for InnoDB type tables which support ADD CONSTRAINT FOREIGN KEY (...) REFERENCES ... (...). Note that InnoDB does not allow an index_name to be specified. See section 7.5 InnoDB Tables. The syntax for other table types is provided only for compatibility, to make it easier to port code from other SQL servers and to run applications that create tables with references.
MEN KAN DET VIRKELIG PASSE ??????????
