What is causing this sqlite foreign key mismatch?

Question

I already checked out this question, and thought I had the answer - but then it didn\'t look right to me.

I have the following pared down example:

CR         


        

Answer 1

The documentation says:

Usually, the parent key of a foreign key constraint is the primary key of the parent table. If they are not the primary key, then the parent key columns must be collectively subject to a UNIQUE constraint or have a UNIQUE index.

In the pipelines table, neither the name nor the owner columns are, by themselves, unique.

I guess you actually want to have a two-column foreign key in the tasks table:

FOREIGN KEY(pipeline, owner) REFERENCES pipelines(name, owner)
