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

这会产生以下输出：

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