According to documentation, parameters needed to connect to HANA database are host, port, user and password.
from hdbcli import dbapi
conn = dbapi.connect(
address="<hostname>",
port=3<NN>MM,
user="<username>",
password="<password>"
)
cursor = conn.cursor()
This selects username as schema by default. Is there a way to specify schema name?
AFAIK there is no connection property that would allow setting/switching to a specific schema.
What you can easily do, however, is to switch to your intended schema right after creating the connection:
conn = dbapi.connect(
address = 'hxehost',
port = '39013', # connecting to the HANA system, not the DB directly
user = '...',
password = '...',
databasename = 'HXE', # using the DB name instead of a port number
#key='USER1UserKey', # address, port, user and password are retreived from the hdbuserstore
encrypt=True, # must be set to True when connecting to HANA Cloud
sslValidateCertificate=False # True HC, False for HANA Express.
)
#If no errors, print connected
print('connected')
c1 = conn.cursor()
c1.execute("SET SCHEMA R_C") # <-- here we set the current schema for the connection
c1.execute("SELECT current_schema FROM DUMMY") # <-- checking the current schema
rows = c1.fetchall(); # <-- [('R_C',)]
This works well for me and I don't see any side-effects besides the additional command to set the schema.
