I need to have a table that supports FULLTEXT searches. This implies
that this table should be a MyISAM table.
However, I also require that this table act as a parent for child tables
in order to support referential integrity. If I create the child tables
as INNODB tables, will referential integrity still work with the MyISAM
parent table?
Many thanks,

Hi
First a simple question ...
I have a table "access_log" that has foreign keys "app_id" and
"app_user_id" that reference the "application_type" and "app_user"
tables. When I insert into "access_log", the referential integrity
triggers generate these queries:
SELECT 1 FROM ONLY "public"."application_type" x

Referential Integrity on one of our production tables seems to have been
lost. I am running Postgres 7.1.3 embedded within Red Hat
kernel-2.4.9-e.49.
Within that I have a table with referential integrity constraints which
no longer work.
I do not know how to disable referential integrity on a column in a table.
I do not know how to view what Postgres thinks my referential integrity

So, as far as I know, PostgreSQL does not have any way of verifying the loss
of referential integrity.
Are there any recommended methods or utilities for checking referential
integrity in a PostgreSQL database?

Hello all,
I am currently on a project which the source data come into the
databases is always dirty (not surprisingly); however, due to the
design of the database, it is very difficult to impose referential
integrity (esp. Foreign Keys) on these tables. Am I just not thinking
straight? This solution is implemented on multi RDBMS.
Example, we have 2 tables, one with a number of columns and a TIMEID
column to specify the load date (in...

Is there a way to run an alter table statement that adds a constraint
for a foreign key, but does *not* check the existing data for
refrential integrity? I'm essentially looking for the equivalent to SQL
Server's NOCHECK flag.
I am able to create equivalent keys in the Relationships screen, as
long as the "Enforce referential integrity" box is left unchecked. But
when I try to create that relationship with an ALTER TABLE statement, I...

I've inadvertently placed this post in another similar newgroup, and I
apologise if you get it twice.
I'm building a database that consists of frontend and backend. Some
of the lookup tables need to reside in the frontend database. The
data in the lookup fields that relate to the backend tables will
never
change, but a descriptor for items in these fields will. I may need
to update the descriptors periodically, hence the need to keep...

Access2000, using a continuous form.
I’m getting a message that say “you cannot add or change a record
because a related record is required in table Employee”.
This occurs in all my combobox fields that have referential integrity
linked to another table. I do not have the field in the table set as
required, and I do not want to require the entry. If the record is
filled out completely and added to the table, you can go back to the...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
