Hello everyone!
When using a parametric SQL View and trying to escape the viewparams
values with backslashes as described in
http://docs.geoserver.org/stable/en/user/data/database/sqlview.html#using-a-parametric-sql-view
it raises the following ServiceException:
*java.lang.IllegalStateException: The specified String ends with an
incomplete escape sequence.*
When looking closer at the documentation and delimiting the String with "
*\;*" the log entry shows that a "*;*" is added at the end of the
substituted parameter, thus resulting in an invalid SQL and in the
following exception:
*java.io.IOExceptionORA-00911: invalid character*
Am I doing anything wrong here?

I'm getting a bit confused here, you do have: viewparams=p_where:\NAME =
'ABC Inc'\;
That is, p_where is assigned the value \NAME = 'ABC Inc'\; or in other
terms, you have an
escaped capital N (which does not makes sense to me?) and a escaped ;,
which seems to be
correctly added to the output.
The escape char is applied only to the subsequent char, and it's needed
only for ; so "\;" becomes
";" in the query. The "\N" probably just becomes "N", but it seems you're
trying to escape a block
of chars, and that's not what escaping does...
