Full outer join gives error in pl/sql procedure in 10G

[ram_jetwani]

Hi all,
I am using following version of oracle.

Oracle Database 10g Enterprise Edition Release 10.1.0.5.0 - 64bi
PL/SQL Release 10.1.0.5.0 - Production
CORE 10.1.0.5.0 Production
TNS for Solaris: Version 10.1.0.5.0 - Production
NLSRTL Version 10.1.0.5.0 - Production


I am using following construct query in a procedure.
The tables tab3,tab4,tab5 and tab6 are equijoined and an inline view is created (tview). Tables tab7 and tab6 are equijoined and an inline view is created (tview2). Tview is full outer joined with tview2 and an inline view is created (tview8). Tab1 is left joined with tview8 to get the desired output.
The query is shown below:

cursor c_test (p1 nummer, p2 nummer)
is
SELECT nummer nummer
, eancode
, begindatum
, einddatum
FROM tab1 t1
, tab2 t2
, (

the above cursor is used in a procedure to fetch data.

The cursor query is returning proper data when executed from sql prompt but while executing it from pl/sql
it gives error :

ORA-00923: FROM keyword not found where expected
The error is coming because of FULL OUTER JOIN used in the query. if i use left outer join or right outer join it runs successfully.but if I use full outer join, it gives above error.

Can any one help me out?

Thanks,
Ram

After raising a tar with oracle, it is confirmed that it is an oracle bug. If we use bind variable in a query which is using Full outer join then it gives the error of From keyword not found where expected. The workaround that I use to solve the problem is instead of using full outer join on the inline views I first left joined the internal view union right join on the same internal views and the expected output was available.
