python中通过cx_Oracle查询表中字段报错，不能用desc tablename吗？请大神赐教啊！

Question

#连接数据库
db_conn = cx_Oracle.connect(db_connect_info)
cursor = db_conn.cursor()

get_base_table_stru = "desc  " + db_base_table
cursor.execute(get_base_table_stru)

db_base_table_content = cursor.fetchall()
for row in db_base_table_content:
    print row

报错：Traceback (most recent call last):
File "C:\Users\victor\Desktop\Ӣ��\DDLDML\ddldml\src\generate_ddl_dml.py", line 107, in <module>

cursor.execute(get_base_table_stru)

cx_Oracle.DatabaseError: ORA-00900: ��Ч SQL ���

Answer 1

desc是sqlplus中的命令，不是合法的sql语句，因此出现了ORA-00900的报错。
如果想查询表的信息，请查询user_tables表。
