我已阅读有关odbc.ini
和iODBC documentation的Vertica documentation。我还看到了一个问题with the same error,但无法按照上一个问题的答案中的建议获得连接字符串。
我目前拥有的内容:
/etc/odbcinst.ini
[HPVertica] Description = HP Vertica ODBC Driver Driver = /opt/vertica/lib64/libverticaodbc.so
/etc/odbc.ini
[ODBC Data Sources] VerticaDB1 = db1 database on HP Vertica [VerticaDB1] Description = db1 database on HP Vertica Driver = HPVertica Database = db1 Servername = 10.0.0.67 UID = dbadmin PWD = Port = 5433 Locale = en_GB [ODBC] Threading = 1
~/.odbc.ini
[DEFAULT] Driver = VerticaDB1
使用isql
[root@ip-10-0-0-67 /]# echo "select 1;" | isql -v VerticaDB1 +---------------------------------------+ | Connected! | | | | sql-statement | | help [tablename] | | quit | | | +---------------------------------------+ SQL> select 1; +---------------------+ | ?column? | +---------------------+ | 1 | +---------------------+ SQLRowCount returns 1 1 rows fetched
odbcinst -j
输出:
unixODBC 2.2.14 DRIVERS............: /etc/odbcinst.ini SYSTEM DATA SOURCES: /etc/odbc.ini FILE DATA SOURCES..: /etc/ODBCDataSources USER DATA SOURCES..: /root/.odbc.ini SQLULEN Size.......: 8 SQLLEN Size........: 8 SQLSETPOSIROW Size.: 8
在Python中使用“VerticaDB1”:
>>> import pyodbc >>> conn = pyodbc.connect("DRIVER={VerticaDB1};UID={dbadmin};PWD={...}") Traceback (most recent call last): File "", line 1, in pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')
在Python中使用“HPVertica”:
>>> import pyodbc >>> conn = pyodbc.connect("DRIVER={HPVertica};UID={dbadmin};PWD={...}") Traceback (most recent call last): File "", line 1, in pyodbc.Error: ('HY000', '[HY000] [unixODBC][Vertica][ODBC] (10430) Not enough information provided to establish a connection to the data source and specified to not prompt for more information. (10430) (SQLDriverConnect)')
答案 0 :(得分:11)
尝试使用DSN
进行连接:
conn = pyodbc.connect("DSN=VerticaDB1;UID=dbadmin;PWD=mypassword")
或者,您可以使用DRIVER
进行连接,但需要提供更多信息,例如数据库,主机和端口:
conn = pyodbc.connect("DRIVER=HPVertica;SERVER=10.0.0.67;DATABASE=db1;PORT=5433;UID=dbadmin;PWD=mypassword")
