py2jdbc is a Python module that accesses JDBC-compliant databases.
It implements the Python Database API Specification 2.0
specification.

pip install py2jdbc
This module currently uses ctypes for ffi access to the JNI API. Other branches will consider switching to Cython/Pyrex or writing pure C++ extensions.
conn = py2jdbc.onnect('jdbc:sqlite::memory:')
c = conn.cursor()
c.execute("""
create table tests(
id integer primary key,
name text not null
)
""")
c.execute("insert into tests(id, name) values (?, ?)", (1, 'Hello World'))
for row in c.execute("select * from test"):
print(row)
c.close()
conn.close()
Or even:
with py2jdbc.connect('jdbc:sqlite::memory:') as conn:
with conn.cursor() as c:
c.execute("""
create table tests(
id integer primary key,
name text not null
)
""")
c.execute("insert into tests(id, name) values (?, ?)", (1, 'Hello World'))
for row in c.execute("select * from test"):
print(row)
Connect to your database with py2jdbc.connect by passing your JDBC URL. By
default, your Java classpath will be loaded from any CLASSPATH environment
variable, and any jar in a lib directory under your current working directory.
You can also pass the CLASSPATH in the connection call:
py2jdbc.connect('jdbc:sqlite::memory:', classpath=['path1', 'path2'])
This returns the Connection object.
Bind variables use question marks, like JDBC, and can bind to sequences or generators:
# insert a row
c.execute("insert into tests(id, name) values (?, ?)", (1, "Hello World"))
# insert 10 rows
c.executemany("insert into tests(id, name) values (?, ?)",
(i + 1, 'testing')
for i in range(10)
)
Selecting from a database will automatically describe the result set and try to convert values to standard Python types:
c.execute("select * from test")
for row in c:
print(row) # -> [1, 'Hello World']
