附件中类型有五类：
1.Short Text， 2.Long Text，3.Image，4.OLE Object, 5.Web Page
--1. 查询 Long Text数据：
SELECT
FAD.SEQ_NUM "Seq Number",
FDAT.USER_NAME "Data Type",
FDCT.USER_NAME "Category User Name",
FAD.ATTACHED_DOCUMENT_ID "Attached Document Id",
FDET.USER_ENTITY_NAME "User Entity",
FD.DOCUMENT_ID "Document Id",
FAD.ENTITY_NAME "Entity Name",
FD.MEDIA_ID "Media Id",
FD.URL "Url",
FDT.TITLE "Title",
FDLT.LONG_TEXT "Attachment Text"
FROM
FND_DOCUMENT_DATATYPES FDAT,
FND_DOCUMENT_ENTITIES_TL FDET,
FND_DOCUMENTS_TL FDT,
FND_DOCUMENTS FD,
FND_DOCUMENT_CATEGORIES_TL FDCT,
FND_ATTACHED_DOCUMENTS FAD,
FND_DOCUMENTS_LONG_TEXT FDLT
WHERE
FD.DOCUMENT_ID = FAD.DOCUMENT_ID
AND FDT.DOCUMENT_ID = FD.DOCUMENT_ID
AND FDCT.CATEGORY_ID = FD.CATEGORY_ID
AND FD.DATATYPE_ID = FDAT.DATATYPE_ID
AND FAD.ENTITY_NAME = FDET.DATA_OBJECT_CODE
AND FDLT.MEDIA_ID = FD.MEDIA_ID
AND FDAT.NAME = 'LONG_TEXT'
--2. 查询Short Text ：
SELECT
FAD.SEQ_NUM "Seq Number",
FDAT.USER_NAME "Data Type",
FDCT.USER_NAME "Category User Name",
FAD.ATTACHED_DOCUMENT_ID "Attached Document Id",
FDET.USER_ENTITY_NAME "User Entity",
FD.DOCUMENT_ID "Document Id",
FAD.ENTITY_NAME "Entity Name",
FD.MEDIA_ID "Media Id",
FD.URL "Url",
FDT.TITLE "Title",
FDST.SHORT_TEXT "Attachment Text"
FROM
FND_DOCUMENT_DATATYPES FDAT,
FND_DOCUMENT_ENTITIES_TL FDET,
FND_DOCUMENTS_TL FDT,
FND_DOCUMENTS FD,
FND_DOCUMENT_CATEGORIES_TL FDCT,
FND_ATTACHED_DOCUMENTS FAD,
FND_DOCUMENTS_SHORT_TEXT FDST
WHERE
FD.DOCUMENT_ID = FAD.DOCUMENT_ID
AND FDT.DOCUMENT_ID = FD.DOCUMENT_ID
AND FDCT.CATEGORY_ID = FD.CATEGORY_ID
AND FD.DATATYPE_ID = FDAT.DATATYPE_ID
AND FAD.ENTITY_NAME = FDET.DATA_OBJECT_CODE
AND FDST.MEDIA_ID = FD.MEDIA_ID
AND FDAT.NAME = 'SHORT_TEXT'
(插入的时候有函数，提取的时候应该也有函数,能批量提取，就基本不是问题了,都有对应的API的,
API : FND_ATTACHED_DOCUMENTS_PKG)
涉及到表如下：
1. FND_DOCUMENTS
2. FND_ATTACHED_DOCUMENTS
3. FND_DOCUMENTS_TL
4. FND_DOCUMENT_DATATYPES.
5. FND_DOCUMENT_CATEGORIES
6. FND_DOCUMENTS_LONG_TEXT (Long text type attachment).
7. FND_DOCUMENTS_SHORT_TEXT (Short text type attachment).
8. FND_DOCUMENTS_LONG_RAW
9. FND_LOBS (File type attachments).
