---------------------------------------
Hello Steven,
I am currently running in the next issue with the insert trigger. When trying to set the
key value, I run into the following error:
TEIID31080 my_nutri_diary.UserDefinedProducts validation error: TEIID31119 Symbol
key.fkProduct is specified with an unknown group context
Have you an idea what is going wrong here? The code:
{noformat}
-- ///////////
CREATE TRIGGER ON UserDefinedProducts INSTEAD OF INSERT AS
FOR EACH ROW
BEGIN ATOMIC
DECLARE long vIdProduct;
DECLARE integer vNumRecords;
-- if a product code was given, check that the user has not already created a product
for this code
-- this situation should actualy never appear
IF (new.idCode IS NOT NULL)
BEGIN
vNumRecords = SELECT 1 FROM UserDefinedProducts_SRC WHERE
fkProfile = new.fkProfile AND idCode = new.idCode
LIMIT 1;
IF(vNumRecords > 0)
BEGIN
DECLARE EXCEPTION e = SQLEXCEPTION 'User defined product already exists'
SQLSTATE '45000';
RAISE e;
END
END
-- check if the user has already reached his MAX amount of UserDefinedProducts;
vNumRecords = SELECT COUNT(*) FROM UserDefinedProducts_SRC WHERE fkProfile =
new.fkProfile;
IF(vNumRecords >= 1000)
BEGIN
DECLARE EXCEPTION e = SQLEXCEPTION 'MAX amount of user defined products exceeded
for this account' SQLSTATE '45000';
RAISE e;
END
-- if all checks have been passed we can safely add the product to the database
INSERT INTO
Products(fkDatabaseKey)
VALUES
(0);
-- create a new record for the user defined product
vIdProduct = cast(generated_key('idProduct') as long);
INSERT INTO
UserDefinedProducts_SRC(fkProduct, fkProfile, idCode, product_name, origins, brands,
quantity,
serving_quantity, nova_group, nutrition_grade_fr, energy_100g,
carbohydrates_100g,
sugars_100g, proteins_100g, fat_100g, saturated_fat_100g, saturated_fat_modifier,
salt_100g, salt_modifier, fiber_100g)
VALUES
(vIdProduct, new.fkProfile, new.idCode, new.product_name, new.origins, new.brands,
new.quantity,
new.serving_quantity, new.nova_group, new.nutrition_grade_fr, new.energy_100g,
new.carbohydrates_100g,
new.sugars_100g, new.proteins_100g, new.fat_100g, new.saturated_fat_100g,
new.saturated_fat_modifier,
new.salt_100g, new.salt_modifier, new.fiber_100g);
-- supply the key value
key.fkProduct = vIdProduct;
END;

When overwriting an Insert trigger with custom logic in a ddl file,
the primary key is not correctly transferred back in the response of the odata layer with
a dummy insert value

Key: TEIID-5782
URL:
https://issues.jboss.org/browse/TEIID-5782
Project: Teiid
Issue Type: Quality Risk
Components: OData
Affects Versions: 12.3
Reporter: Christoph John
Assignee: Steven Hawkins
Priority: Major
Hello,
in the past we had an issue in the odata layer, that the generated primary key of an
autoincrement key was not corretly transfered back in the odata response. This issue was
fixed.
However, the current issues derives from the discussion in
https://issues.jboss.org/browse/TEIID-5763
where we havewritten an INSTEAD OF INSERT trigger. According to my last comment to
https://issues.jboss.org/browse/TEIID-5763, there are two situations which can arrise. I
have to set the 1. key group explicitely or 2. it is set implicitely.
Now in both situations I observe the same result. When I POST an INSERT with a dummy
primary key, say key=0 (as it was NOT NULL in the past, and I am still using the old
sources) I retrieve key=0 in the odata response. Correct would be to get a response with
the generated key instead.
