Re: esql nested query not working - 1.8.2

do you get a different error message when you leave out the quotes?

I've tried it both with and without the single quote and it still doesn't
work.

Here is another clue - the nested query works if I run it against a MySQL
database, it just doesn't work against a Access database.

In a couple of months - we'll be converting the access database.  In the
meantime, is there a solution ( that will work with the access database )?

Try removing the single quotes around <esql:parameter  type
="string"><esql:get-string ancestor="1"  column="rid"/></esql:parameter>

I think by including the single quotes you are making a query that doesn't
use parameters (your where clause looks like "... Main.rid = '?' ", e.g.,
the literal string '?').

I would like to execute a nested query. When  I try to reference a
parameter from the ancestor query I get a  java.lang.RuntimeException:
Error setting parameter on statement : Select title  from Main where
Main.rid='?'

I would greatly appreciate any suggestions. I  have tried to emulate the
example esql - but I can not get it to pick up the  parameter. If I
hardcode the value - the nested query works.

In searching the list - I found a similar posting in January for this error
- but no suggestion/solution was posted.

I am running tomcat/cocoon 1.8.2 on Windows 98 and pointing to an access
database.

I am attaching the related code below:


<snip>

<!-- here is the problem line - if I hardcode the rid this works  -->

<esql:query>Select title from Main where Main.rid='<esql:parameter  type
="string"><esql:get-string ancestor="1"  column
="rid"/></esql:parameter>'</esql:query>
