# 2119 Using a Function with No Parameters in an SQL Join Causes Error

I'm converting our application from v3.24 to v4.21 build 10 and have found some unusual behaviour with left outer join clauses
In our 3.24 app the following sql works fine. However in 4.21 the current date comparisson seems to cause an error:

#11949 SQL Parsing Error - table correlation name j in JOIN clause experssion is invalid.

select
j.jb_JobNo,
MIN(b.CB_Date) as first_ccar, 
MAX(b.CB_Date) as last_ccar, 
b.CB_Reg as first_ccreg, 
a.CB_Reg as current_ccreg
from jobs j 
left outer join bookings b on (j.JB_JobNo=b.CB_JobNo) 
left outer join bookings a on (j.JB_JobNo=a.CB_JobNo) and (a.CB_Date =  Current_date) 
group by
j.JB_JobNo
