我正在尝试使用 PyODBC 在 Python 中查询 Teradata 数据库。与数据库的连接建立正常;但是,当我尝试获取结果时,我遇到了这个错误“十进制的无效文字:u''”。请帮忙。
我在 RHEL6 上,使用 Python 2.7.3
这是代码和结果:
import pyodbc
sql = "select * from table"
pyodbc.pooling = False
cnx = pyodbc.connect("DRIVER={Teradata};DBCNAME=host;DATABASE=database; AUTHENTICATION=LDAP;UID=user;PWD=password", autocommit=True, ANSI=True)
cursor = cnx.cursor()
rows = cursor.execute(sql).fetchone()
