MDB2 MySQL(i) constraints issues

Hi I have come across a problem whilst extending both listTableConstraints() and getTableConstraintDefinition() (in MDB2/Driver/Reverse/ and MDB2/Driver/Manager/ for MySQLi.php) to support Foreign Keys with MySQL. As MySQL handles unique indexes completely separate from FK constraints, both constructs may have an instance of the same name! This means that listTableConstraints (which assumes uniqueness) currently will only bring back one occurance of the name, but bringing back two without reference to the 'type' would make no sense. However apparently the API for these functions is locked down. getTableConstraintDefinition() is worse as it simply will not know which constraint the definition is being requested for. Both functions probably require additional optional parameters and/or extended return variables. Can anyone advise? thanks Rob Siveter -- Premier IT New Premier House 150 Southampton Row London WC1B 5AL t: 020 7837 2690 f: 020 7278 3113
