vertica - ERROR 4286: Operator does not exist: date = int

Question

I get this error, what's wrong? this is the query:

dbvertica=> select Sum(dbvertica.LINEORDER.l_extendedprice*dbvertica.LINEORDER.l_discount) as revenue from  
dbvertica.LINEORDER, dbvertica.DATE where dbvertica.LINEORDER.l_orderdate = 
dbvertica.DATE.d_datekey and dbvertica.DATE.d_year = '1993' and 
dbvertica.LINEORDER.l_discount between 1 and 3 and dbvertica.LINEORDER.l_quantity < 25;

and those are tables:

Answer 1

Your problem is at this row :

dbvertica.LINEORDER.l_orderdate = dbvertica.DATE.d_datekey 

as dbvertica.LINEORDER.l_orderdate is of type date and dbvertica.DATE.d_datekey is of type int.

You will need something like this :

select 
Sum(dbvertica.LINEORDER.l_extendedprice*dbvertica.LINEORDER.l_discount) as revenue from  
dbvertica.LINEORDER,
dbvertica.DATE 
where 
**TO_CHAR(dbvertica.LINEORDER.l_orderdate) = dbvertica.DATE.d_datekey**
and dbvertica.DATE.d_year = '1993' 
and dbvertica.LINEORDER.l_discount between 1 and 3 
and dbvertica.LINEORDER.l_quantity < 25;
