# 3415 Self-Referencing Foreign Key Constraints Not Checked for Current Row During Updates

If a FK constraint is self-referencing (i.e. refrences the same table), the target column is not being checked against the foreign key constraint when the target column values are changed in the same row.

CREATE TABLE "SelfReference"
(
"ParentID" INTEGER,
"ID" INTEGER,
CONSTRAINT "PrimaryKey" PRIMARY KEY ("ID"),
CONSTRAINT "ParentIDKey" FOREIGN KEY ("ParentID")
REFERENCES "SelfReference" ("ID")
ON UPDATE NO ACTION
ON DELETE NO ACTION
)

INSERT INTO "SelfReference" VALUES (NULL,100)
INSERT INTO "SelfReference" VALUES (100,200)
INSERT INTO "SelfReference" VALUES (300,300)

UPDATE SelfReference SET ID=50 WHERE ID=300
