Hi,
can someone tell how to write a Trigger; I am familiar with Sybase Sql
Anywhere trigger syntax.
Actually I have three tables MEMBER, CONTRACT and PAYMENT
I need to update the MEMBER.BALANCE once the PAYMENT.AMOUNT is INSERTED
where PAYEMENT.CONTRAC_ID = CONTRACT.CONTRAC_ID
and CONTRAT.MEMBER_ID = MEMBRE.MEMBER_ID
I have more TRIGGERS to write, but with a good example it would be great

I am extremely new at SQL Server2000 and t-sql and I'm looking to
create a simple trigger. For explanation sake, let's say I have 3
columns in one table ... Col_1, Col_2 and Col_3. The data type for
Col_1 and Col_2 are bit and Col_3 is char. I want to set a trigger on
Col_2 to compare Col_1 to Col_2 when Col_2 is updated and if they're
the same, set the value on Col_3 to "Completed". Can someone please
help me?
Thanks,
Justin

I am running PostgreSQL 7.4.5 and have a trigger on a table called
tblriskassessors which inserts, updates or delete a corresponding record
in tblinspectors by lookup of a contact id and license number match. The
INSERT and DELETE work fine. The UPDATE works good unless I update the
license number. The error, at the bottom of this message, suggests the
primary key violation. But my UPDATE in no way alters the primary key,

Hi there!
I need to write a trigger that will check referential integrity of my
data. I have few FOREIGN KEY constraints but, as You probably konow, the
cannot be deferred (in the meaning of SQL 92 standard). So I decided to

(after secon altertion of my table). But I cannot write a trigger for
ALTER. I found something on msdn, byt their example doesn't work. To

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
