Question

SET ECHO ON 
SET VERIFY ON 

ACCEPT CNUMBER CHAR PROMPT 'CUSTOMER NUMBER == ' 
ACCEPT PNUMBER CHAR PROMPT 'PART NUMBER == ' 
ACCEPT OD date format 'YYYYMMDD' PROMPT 'ORDER DATE == ' 


DELETE FROM ORDERS WHERE CNUM = &CNUMBER AND PNUM = &PNUMBER AND ORDERDATE = to_date(&OD,'YYYYMMDD'); 

PROMPT Done. 

--DELETE FROM ORDERS WHERE CNUM = 'C111' AND PNUM = 'M001' AND ORDERDATE = to_date(20130401,'YYYYMMDD'); 

OUTPUT：

SQL> DELETE FROM ORDERS 
    2 WHERE CNUM = &CNUMBER AND PNUM = &PNUMBER AND ORDERDATE = to_date(&OD,'YYYYMMDD'); 
old 2: WHERE CNUM = &CNUMBER AND PNUM = &PNUMBER AND ORDERDATE = to_date(&OD,'YYYYMMDD') 
new 2: WHERE CNUM = C111 AND PNUM = M001 AND ORDERDATE = to_date(20130404,'YYYYMMDD') 
WHERE CNUM = C111 AND PNUM = M001 AND ORDERDATE = to_date(20130404,'YYYYMMDD')

怎麼啦？

Answer 1

CNUM = '& CNUMBER' AND PNUM = '& PNUMBER'

不確定& OD，你需要引用的是嗎？
