Python ASE & IQ drivers

[pythondev]

Hello,

I would like to execute queries in Python 2 (and 3 if possible) to ASE and IQ Sybase servers.

What are the most performant implementations in Python 2/3 ?

Best regards,

Hi Joe,

We just finished a feature request of Python for ASE. We support Python 3.7 with ASE/SDK 16.0 SP02 PL09, will be out in the next month or so, and 16.0 SP03 PL07, which dropped in June 2019.

Thanks,
Dawn

ASE 16.0 SP03 PL07 just introduced support for Python 3.7, which is quite an improvement over 3.4.

Hi,

Yes, we support Python 2 and 3 for ASE.

$ pwd
/sybase/ase/syb157sp140/OCS-15_0/python

$ ls
python26_64r python26ucs4_64r python31_64r

Versions supported with these modules. Python 2.6.x and 3.1.x on 15.7.

16.0 Sp03 Pl06 includes:
python34_64r Python 3.4.x

You can use SDK 16.0 on ASE 15.7 as well.

Regards,
Ryan

Hi Richard,

For ASE we don't have any information about performance about Python version.
Please check the product manual about Programmer's guide for Python

Also, I've tried using SQL Alchemy to execute queries seemsly on IQ and ASE but it works only for IQ:

import sqlalchemy
from sqlalchemy.dialects import registry

registry.register('sqlalchemy_sqlany', 'sqlalchemy_sqlany.base', 'SQLAnyDialect')
engine = sqlalchemy.create_engine("sqlalchemy_sqlany://{}:{}@{}:{}".format(usr, pwd, host, port), echo=True)
engine.connect()
metadata = sqlalchemy.MetaData()
table = sqlalchemy.Table("MY_TABLE", metadata, autoload=True, autoload_with=engine)
result = sqlalchemy.select([table]).where(table.columns.MY_COLUMN == "MY_VALUE")

Hello joe.woodhouse, where can I download CPython driver to execute queries ? I've read https://help.sap.com/doc/4c40a79c93f4485ca2a01c5ba806c2f5/16.0.3.6/en-US/Adaptive_Server_Enterprise_... but it seems only Python 2 (released in 2012) is available on SourceForge.

I'm looking for a driver that will run on Python 3, GNU/Linux, Windows, IQ and ASE. Does that driver exist ? 🙂

Hi Richard,

Here is the setup using the SAP driver.

SDK 16.0 SP03 PL07:
$ source $SYBASE/SYBASE.csh
$ setenv PYTHONPATH $SYBASE/$SYBASE_OCS/python/python37_64r/lib
$ setenv PATH /pse/hansenr/python37/bin:$PATH

$ cat firstapp.py
import sybpydb
conn = sybpydb.connect(user='DBA', password='sql')
cur = conn.cursor()
cur.execute("select * from mytable")
while True:
row = cur.fetchone()
if (not row):
break
print("%s: %s" % (row[0], row[1]))
cur.close()
conn.close()

$ cat $SYBASE/interfaces
ASE
query tcp ether ASEHOST ASEPORT
IQ
query tcp ether IQHOST IQPORT

isql -UDBA -Psql -SIQ
1>create table mytable (c1 int, c2 varchar(50))
2>go
1> insert into mytable values (1, "test")
2> go
(1 row affected)

isql -Usa -Ppassword -SASE
1> create table mytable (c1 int, c2 varchar(50))
2> go
1> insert into mytable values (2, "test2")
2> go
(1 row affected)

$ setenv DSQUERY ASE
$ python3 firstapp.py
2: test2

$ setenv DSQUERY IQ
Modify username and password
$ python3 firstapp.py
1: test

Hope this helps,

Ryan

Hello ryan.hansen, Python 3.1 is pretty old and deprecated. 3.4 is better but still out of date 😞

Any chance to get a Python 3.7 compatible SAP SDK ?
