sure but you need to know the structure of those tables. you might
want to see if there's a tool that already exists for this database
which does this. it seems to be heavy on the JDBC side so perhaps
there are java tools that do it.

In your knowledge do you think there is a way to use pyodbc to copy all the
tables and data in the table in the datasource to ms sql server and then
after copying it in the sql server use SQLAlchemy for further process?

I would love to code a new dialect for SQLAlchemy but i guess my python
skills are not there yet just started to learn python a few months ago.
What i dont understand is why i can connect to that Datasource using
pyodbc.connect(mydsn) with no problems but SQLAlchemy cant?
Is there any other way
OK this database is an entirely distinct product that has no
particular resemblance to SQL server or anything else.You'd have
to create your own dialect for this. The most fundamental thing to
get working with a dialect is how to fetch identity values for integer
primary keys, for this databa
Hi Mike,
here is the information about Cache Monitor. Its likely similar to MSSQL
thats why i used the msql+pyodbc dialect.
https://www.cachemonitor.de/
Secondly about the print(pyodbc_connection.getinfo(pyodbc.SQL_DBMS_VER)) ==>
*OUTPUT: Cache Objects Version 2012.2.5.962 Cache xDBC Server 8.

oh, so the "InterSystem Cache Database", which I'v
What i think is, in Cache Monitor Database there is no such thing as: SELECT
CAST(SERVERPROPERTY('ProductVersion') AS VARCHAR)
Not like in a MSSQL Server.
Im looking for ways to get the SERVERPROPERTY ProductVersion in Cache
Monitor Database. Cant find how to query that in a Cache Monitor Datab

Both gives me the following error message:

OK that may suggest that it is falling back to the base pyodbc version
management, so here is the updated patch:

Hi -
unfortunately the stack trace indicates a bug in SQLAlchemy in that it
is not interpreting your database's version string correctly.
can you please provide me with the output of:
SELECT CAST(SERVERPROPERTY('ProductVersion') AS VARCHAR)
Additionally, the likely cause of your issue can be w
def __getattr__ (self2, key2):
if False:
pass
elif key2 == "attr_new":
self2.attr_new = sqlalchemy.Column(UUID, sqlalchemy.
ForeignKey(self.RELATED_CLASS.mRID), nullable = True)
else:
return getattr(self2.__class__, key2)
Solved,
return getattr(self2.__class__, key2)

Hello,
I had some database problems (unfinished transactions) so I have wrapped
sqlalchemy database handling functions in following way:
def add(entry, session):
"""Wrapper for db_session.add"""
try:
return session.add(entry)
