Re: Trigger must know his status

[rob@xxxxxxxxx]

I lost a little in the translation of your email.  Let me attempt to
rephrase it.

Are you saying you have an SQL write, and if it fails, what effect does it
have on the trigger program?

If this is what you are saying then it becomes important to consider when a
trigger program is called.  You can set up a trigger program to be called
before, or after, a write.

I have a trigger which is activated before a write.  The reason I have this
is to do some basic referential integrity against some BPCS files.  BPCS
uses multiple members (yuck) therefore you cannot use the built in
referential integrity of the 400.  I can actually cause the sql write to
fail if I don't feel it has my definition of referential integrity.

If you set up a trigger to be performed after a write then it will never be
called if the write has failed.

Clear?  Is this what you asked?

Hi guys,

a trigger program must do some actions before
it ends.

Example:

SQL-Operation or WRITE/UPDATE Operation on a file
-->     TRIGGER

If the SQL, the WRITE/UPDATE Oper. ends the trigger
must do some operations

Is this possible ?
