Hello everybody

I am using Firebird 2.1

I have a parent table (MOVIMCAB) and a child table (MOVIMDET)

In a trigger of MOVIMDET I want to access a value of MOVIMCAB, something
like that:

IF (MOVIMCAB.MVC_TIPMOV = 'E') THEN
UPDATE ....

but the message "column unknown" appears. Why? How I can know the value of
the related column of MOVIMCAB?

MOVIMDET has a foreign constraint:
ALTER TABLE MOVIMDET ADD CONSTRAINT FK_MOVIMDET1 FOREIGN KEY (MOV_IDENTI)
REFERENCES MOVIMCAB(MVC_IDENTI);

Thanks in advance.
