Hi
I need to generate update/delete/insert SQL for a proprietary system that
has an oracle database.
(The system will pass the SQL onto the oracle database but for lengthy
reasons, it needs to go through the proprietary system)
I'm using SQLAlchemy to query the oracle database directly, i then
Ahhh
That would be better than my option A), but not as good as option B)
I read that document earlier tonight too.

Is there an easy way to make it begin a transaction, execute the sql and then
rollback?

Hi All
I'm reflecting a postgresql schema and then taking a str() of the
column types, It goes well until it hits a double field type.
here is the str of my reflected column object:
set: set([Column(u'ASSET_ID', DOUBLE_PRECISION(precision=53,
asdecimal=False), table=tbl_SITES)])
Here is the
Thanks Michael
Is this in the manual anywhere?

I have a mapper extension that gets before_update called, but not the

I'm using 0.5.6 branch from SVN
Here are the relevant lines of code to verify that the correct

Problem solved.
I had another mapper extension which only overrides the after_XXX
functions and it wasn't returning EXT_CONTINUE
Sorry.

I was trying to do the same thing, But i wanted a different
discriminator for the second level of inheritance.
I changed mine to use the same polymorphic_on for both levels and it
seemed to work for me (although not exactly how i wanted it to be)
My suggestion is :
Get rid of your engineer_id
= Column(Integer, ForeignKey('tblReconcilerActions.id'),
primary_key=True)
revision = Column(String)
comment = Column(String)

I've been reading the documentation for ages and i can't figure out
why when i print the results a query from my inherited table, It just
prints them as the base type.
I was hoping someone here would be nice enough to help me solve this
problem.
I thought the last print statement would
Sounds like you are working with Intergraph GIS, Is that correct?

I used a mapper extension.
On before_update, It will copy the record and add it to an array.
On after_update, It will store the new record which is an exact copy
of the old record before the update.

Sounds reasonable and fairly simple to do.
I think you would need two tables.
One for the tasks to be done an another for tasks completed (the
history you wanted)
It sounds like you would need the following functionality
* Insert record - Adding records to the que
* Qurey record - Finding the
Anyone?
I'll take that as a No.

Otherwise, I'll write one myself.

From what i understand, The Dialect objects in sqlalchemy construct
SQL statements from objects constructed in SQLA (ORM, ect)
What can i use to interpret SQL and turn it back into SQLA (or other)

Hi,
Is there a way of telling if a table is inherited from another table
and which tables it inherits from in the Metadata?
Further to this, Is there a way of telling which column definitions
come from which table?

Thanks, I'll look at that but it doesn't sound very concrete.
IE using a foreign key to see if somethings inherited.
Question 1
From the sqlalchemy mapper configuration, PostGreSQLs version of
inheritence sounds like the concrete variary, as it automatically
joins the tables together with a
I'll look into a) do the mappers pick up foreign key constraints and
the polymorphic/inherited details from the metadata when their created
or do you have to specify them? - As a last resort i can query the

Hi
I had that same problem :-)
The problem is that you declare are mapping to class that already has
mapper defined for it.
To work around this, I declared the class i mapped inside a function
so a new class is defined every time i need to create a mapper.
