14 rows selected.
and i have used used empno as user id and assigned it to
:global.u ,ename as password and assigned it to
:global.p
.
In a new_form i called a new emp_connect.fmx file
in that data block
i gave target data source type as :from query clause
source as (select * from emp start with empno=:global.u connect by prior empno=mgr order by deptno,level)
and created items and canvas.
I executed the form login.fmb and opened the form emp_connect.fmb
but when i tried to execute the form using [cntrl+F11].
it throws an error FRM-40505: ORACLE ERROR: unable to perform query.
but if i use the following query in from clause query of emp_connect's data block, then it works fine
(select * from emp start with empno=7566 connect by prior empno=mgr order by deptno,level)
please find the login .fmb file in the attachment . i will sent emp_connect.fmb file in next message.
Thanks In advance.
Regards,
Jay.
