More generic connections available for database (jdbc, odbc, oledb, sql alchemy, adbc...)

[simonaubertbd]

Hello,

As of today, connections to data are limited for databases. I think you would impact waaaaay more users if you leverage standards connectors (jdbc, odbc, oledb, sql alchemy, adbc...) and only after make some dedicated connectors to major databases.

Best regards,

Thank you Simon, that's very helpful feedback! I'll take a look

I'll add odbc soon, adbc is still experimental or beta but is very interesting for performance purposes, thanks for the pointers.

Hello @tgourdel Thanks. For ADBC, yes, it's very young and promising. However, from a strategic perspective, it could be a competitive advantage that can help amphi recognition as probably the only etl tool with it.

Best regards,

Hello @tgourdel
I think you can leverage pyodbc for generic odbc connections. (https://pypi.org/project/pyodbc/ )
Some code I have used to connect python to monetdb
`#import library
import pyodbc
#test there is DSN (not mandatory)
pyodbc.dataSources()
#connect to a DSN even it the db is officially not supported. In Amphi, we should have the choice between DSN and connection string
cnxn = pyodbc.connect('DSN=MONETDB_SAU;SCHEMA=demo', UID='monetdb', PWD='*****')
#write the query
num_order = cnxn.execute("select toto,count() from formation.test_alteryx group by toto")
records = num_order.fetchall()
for r in records:
print (r)

and for generic adbc, maybe https://pypi.org/project/adbc-driver-manager/#description but this definetely requires more work to understand the concepts.

Thanks for testing Simon, I've released a first iteration of an ODBC Input. So from what I understood, everything can go into the connection string.
https://github.com/mkleehammer/pyodbc/wiki/Connecting-to-databases
So if I'm not mistaken, when using DSN, you can add it in the connection string. The components probably needs some improvement later on.

@tgourdel Thanks. Basically, it works !

The things you can improve here is to make it easier, like examples of how to use it with a DSN or a real connection string. And maybe a way to construct the connection string with the DSN, by retrieving it from the DSN list.

But yes, the feature is here and for me, it's one of the biggest change ever for Amphi !

Best regards,

Simon
