Query Generator Funny error message

Question

Hello Experts, Not sure if you ever seen something like this, but be great if anyone can offer me some insight...
on a normal query with parameter I have something like thsi
/*select from ORDR t0*/
declare @begandate as datetime
/* where */
set @begandate = /* t0.docdate*/ '[%0]'
and it runs fine with just about any table, view...etc.. But as soon as you have a UDT in SBO... put in like
/*select from ORDR t0*/
declare @begandate as datetime
/* where */
set @begandate = /* t0.docdate*/ '[%0]'
select * from dbo.[@bos_del_pri] a inner join ordr b on b.u_prioritycode = a.code
where b.docdate = @begandate
it give me funny error messages, "Only one epxression can be specifed in the select list when the subquery is not intrudoced with Exist"
This is ran at a SBO 2005B PL35... when I ran a similar query in SBO 2005A PL45 I get soemthing like
"must specify table to select from".. I know this error message doesn't make sense, but not sure if anyone has encounter the same problem, and if yes possible solutions?
Thank You

Hello Friends,
This is in accordance to provide the information that Query Generator does not work with parameters and User defined tables together. As per my experience in SQL UDT tables start with "@" and variables declared in SQL are also prefixed with "@" so SQL does not make any difference between UDT of SAP and variable of SQL. Thus we are not able to use ([%0] parameters and UDT tables) together.
Please correct me if I am wrong.
Please forgive me if i have posted wrong information  
I look forward to your reply.
