Обсуждение: Update in all tables

    Hello everybody I need to update a field with the same value in the tables of my data base but this field exists
inalmost all tables and has the same value, I don't want to code a script, so my question is if there is some way to
updatethat field with a query and affects all the tables that contain the field?<br /><br />     Thanks in advanced,
regards!!!

No, sorry.  While we're at it, though, if you have the same field in
several tables, it's a good sign that your database is badly
normalised.  You shouldn't have to update more than one table (which
is why there isn't a way to do this automatically).

Unless they're all FK/PK pairs, in which case you on update / delete
cascade FKs.

It's entirely too bad this has to be designed into the DDL for the table.  It'd be nice if you could specify "CASCADE"
onUPDATE or DELETE queries.  I don't see that it's any more of a gun than ON UPDATE/ON DELETE CASCADE in the foreign
keydefinition.
