Hi,

Yes, you can use placeholders. Even dynamically created queries can use
placeholders.

As for SQL-2, you need to use single quotes, not double quotes. Example:

    SELECT * FROM [cq:PageContent]
    WHERE [aProperty] <> 'Joe''s Taxi'

You only need to escape single quotes, using a single quote escape
character:

    String aValue = "Joe's Taxi";
    String sql2Query = "SELECT * FROM [cq:PageContent] " +
        "WHERE [aProperty] <> '" + aValue.replaceAll("'", "''") + "'";


If you want to use XPath, you can use single quotes or double quotes, but
usually single quotes are used as well (the same as in SQL-2). XPath
queries don't support placeholders currently.


Regards,
Thomas
