cx_Oracle：如何获取ORA-xxxxx错误号？

Question

在try / except块中，如何提取Oracle错误号？

Answer 1

try:
   cursor.execute("select 1 / 0 from dual")
except cx_Oracle.DatabaseError, e:
   error, = e
   print "Code:", error.code
   print "Message:", error.message

这导致以下输出：

Code: 1476
Message: ORA-01476: divisor is equal to zero
