DbMetal chokes on repeated foreign key references in SQLite - any ideas?
I've been struggling to get DbMetal to process my SQLite database. I finally isolated the problem. It won't allow a table to have two foreign key references to the same column.
For example, a SQLite database with these two tables will fail:
CREATE TABLE Person
(
Id INTEGER PRIMARY KEY,
Name TEXT NOT NULL
);
CREATE TABLE Match
(
Id INTEGER PRIMARY KEY,
WinnerPersonId INTEGER NOT NULL REFERENCES Person(Id),
LoserPersonId INTEGER NOT NULL REFERENCES Person(Id)
);
I get this error:
DbMetal: Sequence contains more than one matching element
If I get rid of the second foreign key reference, no error occurs.
So, this works:
CREATE TABLE Match
(
Id INTEGER PRIMARY KEY,
WinnerPersonId INTEGER NOT NULL REFERENCES Person(Id),
LoserPersonId INTEGER NOT NULL
);
But I really need both "person" columns to reference the Person table.
I submitted a bug report for this, but I开发者_如何学C could use a workaround in the meantime. Any ideas?
I just had the same problem and created a patch. I've also posted it at your bug report. For others, you can find the patch here: http://pastebin.com/VhNptMqp.
