Different error messages from different env while fetching ref cursor

Question

Hi<br>
I have a package where i need to call one of the procedure.I this <br>
procedure i am returning a refcursor as out parameter.Before returning refcursor i <br>
am doing i am checking a condition if it is satisfied then I am saying return or else<br>
it will proceed and refcursor is assigned for out parameter.So i am speakig about <br>
the condition where i am exiting from procedure before refcursor parameter is <br>
assigned .And later i am tring to fetch from that cursor .So i am getting different <br>
kinds of errors which i described as follows <br>
<br>
<br>
So If execute that procedure from sqlplus uing <br>
<br>
<br>
var m ref cursor<br>
DECLARE<br>
Y NUMBER;<br>
Z NUMBER;<br>
A NUMBER;<br>
BEGIN<br>
A:=campa.dtl_inq(2,100070875,'R',Y,Z,:M);<br>
END;<br>
<br>
Then if say<br>
Print m<br>
It gives <br>
<br>
ORA-24338: statement handle not executed<br>
<br>
And if i execute this using vb application <br>
<br>
I am getting following error <br>
<br>
ORA-01023: Cursor context not found (Invalid cursor number)<br>
<br>
So i am serching the reason for different errors<br>
<br>

The error depends on exactly what OCI calls the client software makes in accessing this invalid (null) ref cursor variable.
It would seem that SQL*Plus makes different calls than what your code and Visual Basic does - thus the different error messages returned by the two applications.
