Hi,
I have a script that's basically been running unmodified for years. In
it, it performs an SQLAlchemy query that does a simple join between
two tables:
platePointing =
session.query(PlatePointing).join(Plate).filter(Plate.plate_id==plateid).one()
Suddenly, I'm getting a "NoResultFound" error on this. I've double
checked the values in the database; the row - a single matching row -
is in fact there. I turned on "echo" to output the raw SQL queries. I
copied and pasted the query that SQLAchemy generated into the
database, and sure enough it finds the row. The same script/query
finds the appropriate row for some values but not others.
Since the raw SQL query generated by the line above finds the row but
it fails in the script, I'm at a loss on how to proceed to debug this.
Any suggestions would be appreciated.
have you upgraded cx_Oracle to 5.2 lately? An API change was
introduced which corresponds to some users reporting this issue. The
issue is fixed for SQLAlchemy 1.0.9.
Cheers,
Demitri
