When I insert to table new row and after this in the same transaction I del=
ete this row I get such error:=20
triggered data change violation on relation "tbl_b"
I've created database using simple script:
CREATE TABLE tbl_a
(
pn_id SERIAL,
pn_a VARCHAR(400) NOT NULL,
PRIMARY KEY (pn_id)
);
CREATE TABLE tbl_b
(
pc_id INT4 NOT NULL REFERENCES tbl_a (pn_id) ON UPDATE CASCADE ON DE=
LETE CASCADE,
pc_b VARCHAR(40) NOT NULL,
PRIMARY KEY (pc_id, pc_b)=20=20
);
INSERT INTO tbl_a VALUES (1, 'xxx');
And this is the sample script that I use to generete this bug:
begin transaction;
insert into tbl_b values (1, 'xxx');
delete from tbl_b where pc_id=3D1;
ERROR: triggered data change violation on relation "tbl_b"
