数据库SQL Developer

Question

使用SQL Developer需要项目帮助。我似乎无法让程序从表中检索信息。输出显示N / A＆＃39;而不是价值观。

DEFINE V_MESS = 'ORDER NOT FOUND!! Rerun the program!!!'
DEFINE V_PARTNUM = 'N/A'
DEFINE V_PARTDESCRIPTION = 'N/A'
DEFINE V_CURRQTY = 'N/A'
DEFINE V_SUPPCODE = 'N/A'
DEFINE V_SUPPNAME = 'N/A'
DEFINE V_ORDERED = 'N/A'
DEFINE V_RECEIVED = 'N/A'
DEFINE V_QTY = 'N/A'


ACCEPT V_ORDNUM NUMBER format 9999 PROMPT 'Enter Order Number to Receive      (format 9999): '
--input should be 1010

SET TERMOUT OFF
SPOOL \IS380\receive.sql

FROM PART P, SUPPLIER S, ORD O
WHERE O.SUPPLIER_CODE = S.SUPPLIER_CODE

AND O.ORD_NUM = &V_ORDNUM;

SPOOL OFF

PROMPT SP2-0137: DEFINE requires a value following equal sign
PROMPT
PROMPT Order Found. Verify the following:
PROMPT

PROMPT Part Number               : &V_PARTNUM
PROMPT Part Description          : &V_PARTDESCRIPTION
PROMPT Current Inventory Quantity: &V_CURRQTY
PROMPT
PROMPT Supplier Code: &V_SUPPCODE
PROMPT Supplier Name: &V_SUPPNAME
PROMPT
PROMPT Date Ordered    : &V_ORDERED
PROMPT Date Received   : &V_RECEIVED
PROMPT Quantity Ordered: &V_QTY

PROMPT ** Again, verify order information:                                           **
PROMPT ** In case of discrepancy (Order not found, Wrong quantity, etc.)          **
PROMPT **     Press [CRTRL] [C] twice to ABORT                                    **
PAUSE  ** If correct, press [ENTER] to continue
