当我打电话给你时cursor.executemany()

Question

当我打电话给你时cursor.executemany(). 此错误仅在数据较大时发生。我试了一些数据，结果很好。拜托，我对python和编程还不熟悉。谢谢各位。。。在

import string, cx_Oracle, time
startscript = time.time() 
ora_conn = cx_Oracle.connect("")      
ora_cursor = ora_conn.cursor()      

ora_cursor.execute("truncate table table")

ora_cursor.execute("""SELECT * FROM schema.tableA""")


ResultSet_Py_List = []
for column1, column2, column3 in ora_cursor:
     try:
       ResultSet_Py_List.append((column1, column2, column3 ))
     except AttributeError: 
       pass


ora_cursor.prepare("""INSERT INTO schema.TableA (column1, column2, column3 ) 
        VALUES (:column1, :column2, :column3)""")

ora_cursor.executemany(None, ResultSet_Py_List)
ora_conn.commit()

解决了。我发现这和记忆有关。在我发现32位只能使用4GB的RAM之后，我安装了一个64位的python和oracle客户端
