On the above is all my table query, try to use substitution variable to display data. Code below

SELECT u.user_name,l.location_name,b.usages,to_char(cast(b.timebooked as date),'DD-MM-YYYY')as "DATE"
FROM staffaccount s
JOIN bookingstaff b
ON b.staffaccount_id = s.staffaccount_id
LEFT OUTER JOIN users u
ON u.user_id= s.user_id
LEFT OUTER JOIN location l
ON l.location_id= b.location_id
WHERE l.location_name LIKE '%Staff%'
AND timebooked
BETWEEN date&
AND date&

with the code, here is the result for it. (first substitution variable: '2017-01-01' , second substitution variable:'2018-02-10')

http://prntscr.com/iztftx < 用 myOra 显示的结果

But when i tried to add ORDER by usages, it will show error.

错误：

Never allowing me to enter second substitution variable

Answer 1

应该是 &var 而不是 var&

WHERE l.location_name LIKE '%Staff%'
AND timebooked BETWEEN &date  AND &date    
ORDER BY  usages

为了更好的可读性

WHERE l.location_name LIKE '%Staff%'
AND timebooked BETWEEN &date1 AND &date2    
ORDER BY  usages
