If I do
CREATE TABLE Sample (
id INTEGER PRIMARY KEY AUTOINCREMENT,
parent_id INTEGER,
CONSTRAINT p FOREIGN KEY (parent_id) REFERENCES Sample (id)
);
I don't get any errors and the schema behaves as expected. But if I try
CREATE TABLE Aliases (
alias_id INTEGER PRIMARY KEY AUTOINCREMENT,
real_name TEXT NOT NULL,
aka TEXT NOT NULL,
CONSTRAINT xyz UNIQUE (real_name, aka),
CONSTRAINT noCircularRef_A CHECK (
real_name NOT IN (SELECT aka FROM Aliases)
),
CONSTRAINT noCircularRef_B CHECK (
aka NOT IN (SELECT real_name FROM Aliases)
)
);
I am getting an `Error: no such table: Aliases` error. So how do I
implement this constraint? Are there any special keywords, like NEW and OLD
of trigger statements, to refer to current table?
