Hi to alls,
I have a problem with import and export real/float datatype from postgres
to spatialite and viceversa.
I have a table with some colums defined like this:
Column('skeleton_lenght', Float(2,2))
The sqlalchemy method charges the table in a Postgres DB and in a
Spatialite DB

Hi,
if I create many or request with a little number of id (list populated
with 10 values), the script return to me this message: Expression tree is
too large (maximum depth 1000)
So, It's possibile there is a limit for sqlite? This is a big problem for
using sqlalchemy/sqlite.
I cannot

Hi to all,
I looked for around the web without success.
I need to reproduce this kind of SQL distinct query:
SELECT DISTINCT column1 from table where column3= 'Value'
or two or more:
SELECT DISTINCT column1,column2 from table where column3= 'Value'
I tried something like this without success:
with a percent sign).

I try to use the code in this way (query LIKE with OR operator)
res = session.query
Hi, and thanks for reply.
I try to use it but I make for sure a mistake:
def test_not_like(self): self.table_name = 'site_table' Session =
sessionmaker(bind=self.engine, autoflush=True, autocommit=True) session =
Session() query = session.query(SITE) table =
Table(self.table_name,self.metadata,
properly the result I expected but is a LIKE query, but I
need a NOT LIKE operator as I wrote in the object of this topic.
It's possible I didn't understand yours suggestion?
mmm...any ideas?
Thanks a lot fon any help.
Bye

Hi to all,
I need to realize a query like this
select * from my_table where field not like %value1% and field not like
%value2%
with a sqlalchemy sintax. I looked for around the documentation but it
seems be impossible.
Am I wrong? It's possible that the only way could be to use the
13 matches
