Hi,
is it possible to combine joined and single table inheritance in the
same inheritance hierarchy?
In the code at the bottom I want to use the persons table as a base
for the Person, Employee and Manager classes and the employees table
to store the particular fields of Employee and Manager.
I'
Who knew that marking a field as non-null didn't really make it non-
null? Apparently you have to add the following to your my.cnf to tell
MySQL your're actually serious about enforcing things:
sql-mode='STRICT_TRANS_TABLES'

here is the usual way:
page = Session.query(Page).filter(Page.url == url,

what happens if you just say, cursor.execute("select * from
aaa_test(pWhen=>:arg1", {'arg1':None}) using raw cx_oracle (and then
cursor.fetchall()) ? do
Here's a pattern that I see a lot that SQLAlchemy doesn't really seem to
support: update a row if it exists, or insert it if it doesn't.
Imagine you're writing a web spider, so you've got a table with a
primary key of the URL, with another column for the page's body. Your
spider comes across a p

in_ is a method that exists on a column. You pass it the list of
things that the column value should be in. For example, if you have a
class called MyClass that is mapped to a table and has a column called
id, you can do:
session.query(MyClass).filter(MyClass.id.in_( [ 3, 4] )).all()

Hello,
I would like to use the IN construct in one of my queries:
i.e. WHERE c.id IN (..subquery here)
But I can't find any sqlalchemy support for It. It's hvery hard to
search for :(
Anyone know?
Thanks

There is an autocode tool that, although with some glitches on it own,
does exactly what you are looking for.
See http://www.sqlalchemy.org/trac/wiki
Using cx_Oracle, the following does the trick (note this is a
contrived example):
def test(orcl_conn):
curs = orcl_conn.cursor()
cursorToBind = orcl_conn.cursor()
curs.execute("""begin
:cr1 := aaa_test(pWhen => :arg1);
end;""", arg1 = None, cr1 = cur
