Web Agent Error

Question

Hi
I get the following errors when trying to use the SQL query in the Web Agent URl
What's the problem?
The URL is: http://nandeep/intermedia/kewlminds/mediaget/?ord_sql=select+t.id+from+image+t+where+t.id%3d1
The page display the message as
"The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
The error is as follows:
MWM-00015: event logged at 25-Aug-2000 14:42:30 web agent 'interMedia'
MWM-00013: request: method='GET' path='/intermedia/kewlminds/mediaget/' client=10.1.2.34
MWM-00615: error binding a parameter or placeholder 'ID'
MWM-00756: the parameter mode for the request specific argument is not IN
MWM-00015: event logged at 25-Aug-2000 14:43:31 web agent 'interMedia'
MWM-00013: request: method='GET' path='/intermedia/kewlminds/mediaget/' client=10.1.2.34
MWM-00615: error binding a parameter or placeholder 'ID'
MWM-00756: the parameter mode for the request specific argument is not IN
The IMAGE table has the following fields
ID number(10) primary key
title varchar2(100),
image ordsys.ordimage
the application works fine with Clipboard though
Can anyone also let me know where I can get some detailed documentation regarding passing SQL queries a s a string to Web Agent?
It would be of great help if I can get some reply ASAP
thank you

Hi,
To use a SQL SELECT statement instead of a PL/SQL procedure, you must use the same reserved names for items in the select list as would be used for parameter names in a PL/SQL procedure. Try the following:
select t.image.getcontent() ord_content_blob,
t.image.getcontentlength() ord_content_length,
t.image.getmimetype() ord_content_type
from images t where t.id=1
Or as a query-string parameter:
?ord_sql=select+t.image.getcontent()+ord_content_blob,t.image.getcontentlength()+ord_content_length,t.image.getmimetype()+ord_content_type+from+images+t+where+t.id%3d1
Hope this helps,
Simon
