I need to update the primary key field in two tables sharing this field,
I can't update separately because I get an integrity violation message
that tells me the field is still being referenced from the other table,
fair enough but is there any way of doing a joined/linked/double update
to the primary key of both tables simultaneously? Something like: UPDATE
table1.fieldx, table2.fieldx SET fieldx='yyyyy' WHERE fieldx='zzzzz';
