这段代码什么意思is '反馈信息'; -- Create/Recreate indexes create index WMS_PO_TRANSACTION_HEADER_N1 on CUX_WMS_PO_TRANSACTION_HEADER (CREATION_DATE, DECODE(RETURN_CODE,'S','S','E')) tablespace APPS_TS_TX_DATA pctfree 10 initrans 2 maxtrans 255 storage ( initial 64K next 128K minextents 1 maxextents unlimited pctincrease 0 ); create unique index WMS_PO_TRANSACTION_HEADER_U1 on CUX_WMS_PO_TRANSACTION_HEADER (ERP_MESSAGE_NO) tablespace APPS_TS_TX_DATA pctfree 10 initrans 2 maxtrans 255

这段代码是创建或重建了两个索引，分别为"WMS_PO_TRANSACTION_HEADER_N1"和"WMS_PO_TRANSACTION_HEADER_U1"，用于CUX_WMS_PO_TRANSACTION_HEADER表。第一个索引包含两个列，分别为CREATION_DATE和RETURN_CODE，其中RETURN_CODE的值为'S'时，使用静态索引（S）；否则使用动态索引（E）。第二个索引是基于ERP_MESSAGE_NO列创建的唯一索引。这两个索引都使用了名为APPS_TS_TX_DATA的表空间，设置了一些存储参数如pctfree、initial、maxtrans等。

这段代码创建了一个名为CUX_WMS_PO_TRANSACTION_HEADER的表，其中包含多个列，包括erp_message_no、po_number、erp_order_type、org_code和header_id等。这些列的数据类型有VARCHAR2、NUMBER和DATE等，有些列被设置为非空（not null）。表使用名为APPS_TS_TX_DATA的表空间，设置了一些存储参数如pctfree、initial、maxtrans等。

接下来的注释是给表中的列添加注释，例如erp_message_no列的注释是“接口编号”，po_number列的注释是“采购订单号”，以此类推。

最后，代码创建了两个索引，WMS_PO_TRANSACTION_HEADER_N1和WMS_PO_TRANSACTION_HEADER_U1，用于CUX_WMS_PO_TRANSACTION_HEADER表，分别基于CREATION_DATE和ERP_MESSAGE_NO列。这些索引也使用了名为APPS_TS_TX_DATA的表空间，设置了一些存储参数如pctfree、initial、maxtrans等。

FileNotFoundError: [Errno 2] No such file or directory: 'data/original_images/images/data\\NYU2_1130.jpg'

This error message indicates that the program is trying to access a file that does not exist in the specified directory. Specifically, it is looking for a file called 'NYU2_1130.jpg' in the directory 'data/original_images/images/data'.

There could be several reasons why this file does not exist. It could be that the file was accidentally deleted, moved to a different directory, or was never created in the first place. It could also be that there is a typo in the file name or directory path, causing the program to look in the wrong location.

To fix this error, you should check the file name and directory path to make sure they are correct. If the file does not exist, you may need to recreate it or obtain it from a different source.
